All datasets were reconstructed in 5% steps of R-R interval. The optimum phases were chosen where the maximal and minimal diameters were shown. The degree of systolic compression of MCA was calculated. The correlation between length and depth of MB and the degree of systolic compression of MCA were analyzed by Pearson test.Results: The minimal diameters were found in 27 sites (90.0%) from 30% to 35% R-R interval, and the maximal diameters were found in 27 sites (90.0%) from 70% to 80% R-R interval. The correlation between systolic compression of MCA and length of MB was not significant (r=0.096, P=.613); however, the correlation between systolic compression of MCA and the depth of MB was significant (r=0.675, P<.01).Conclusion: The minimal and maximal diameters of MCA are usually demonstrated in 30–35% and 70–80% R-R reconstruction interval, respectively. The degree of systolic compression of MCA correlates well with the depth of MB.Myocardial bridging on dual-source computed tomography: degree of systolic compression of mural coronary artery correlating with length and depth of the myocardial bridgeShi-he Liu, Qing Yang, Jiu-hong Chen, Xi-ming Wang, Min Wang, Cheng Liu10.1016/j.clinimag.2009.05.010Clinical Imaging 34, 2 (2010)2009-08-28Clinical Imaging2009-08-28342S0899-7071(10)X0002-XOriginal Articles8388http://www.clinicalimaging.org/article/PIIS0899707109002332/abstract?rss=yesAbstract: Aim: To investigate the feasibility of using diffusion-weighted MR imaging (DWI) to accurately measure breast cancer extension.Materials and Methods: The extensions of 59 breast lesions were investigated on DW images and apparent diffusion coefficient (ADC) maps and compared to the pathological exams.Results: Three groups were observed: accurate, overdiagnosis, and false negative.

Due to the recent advances in cancer therapy, which include chemoradiation therapy pre- and postoperatively, survival has improved. Radiologist has become an integral part of the patient management team to diagnose and localize the area of recurrent rectal cancer. Although typical pathways of rectal cancer spread have been described, recurrence may occur in unexpected locations due to the currently available aggressive therapy being able to control local disease. Imaging surveillance should include careful evaluation of expected and unexpected anatomic sites where tumor may recur. This paper will describe the common and uncommon locations of recurrent rectal cancer.Multimodality imaging of usual and unusual sites of metastasis which occur after definitive therapy for rectal cancerPriya Bhosale, Janio Szklaruk, Revathy Iyer10.1016/j.clinimag.2007.12.012Clinical Imaging 34, 2 (2010)2010-01-15Clinical Imaging2010-01-15342S0899-7071(10)X0002-XOriginal Articles100108http://www.clinicalimaging.org/article/PIIS0899707109001156/abstract?rss=yesAbstract: Purpose: The aim of the study is to assess the relationship between serum liver enzyme level, hepatic virus infectious state, and standard uptake value of liver on 2-fluoro-2-deoxy-D-glucose (FDG)-positron emission tomography (PET).Material and Methods: It is the retrospective review study from September 2005 to September 2007. A total of 354 healthy subjects referred from the Department of Community Medicine and Health Examination Center of our hospital for health screening were reviewed retrospectively and recruited for analysis. Whole-body FDG-PET, serum liver enzyme levels [aspartate aminotransferase (AST) or SGOT and alanine aminotransferase (ALT) or SGPT], and hepatic B (HBV)/hepatic C virus (HCV) infectious states by checking serum antibodies were performed in all subjects. The mean and maximal values of standard uptake values (SUV) of liver were calculated. The relationships between serum liver enzyme levels, hepatic virus infectious states, and standard uptake values of liver on FDG-PET were evaluated.Result: There is statistically significant positive correlation between SGOT/SGPT and SUV of liver on FDG-PET. However, there are no significant differences in the SUV of liver on FDG-PET between HBV/HCV infection and nonhepatic virus infection subjects.Conclusion: High FDG uptake in the liver because of high level of SGOT/SGPT may lower the diagnostic sensitivity of hepatic malignant or infectious lesions on FDG-PET. For avoiding false-negative findings, careful evaluation of liver on FDG-PET and correlation with other clinical manifestations should be recommended in patients with high level of SGOT/SGPT. Nevertheless, neither HBV/HCV infectious states significantly influences on the SUV of liver on FDG-PET.Positive correlation between serum liver enzyme levels and standard uptake values of liver on FDG-PETChun Y.

Eight consecutive patients [age range, 19–46 years (mean, 28.6 years); M/F ratio=7:1] who underwent operation for FAI were analyzed. We analyzed bump, acetabular retroversion and protrusion, and osteoarthritis in the radiographs. In MR arthrography, we analyzed α-angle, anterolateral labral tear, cartilage abnormality, herniation pit, paralabral cyst, subchondral cyst, and marrow edema. We correlated the imaging findings with operative findings. In the radiographs, all eight patients showed bump and osteoarthritis (Kellgren–Lawrence score II–IV), and five (62.5%) patients showed acetabular retroversion. In MR arthrography, anterolateral labral tear and mild cartilage abnormality (Outerbridge grade I and II) were seen in all eight patients; increased α-angle was seen in six cases (75%). Anterolateral labral tear, bump, and mild cartilage abnormality were seen in all eight patients during operation. According to the above findings, we divided the patients into three cam-type and five mixed-type FAI. In the five mixed-type FAI, both bump and acetabular retroversion were seen. The mixed-type FAI is the most prevalent type in our study. The main imaging findings of mixed-type FAI were acetabular retroversion, bump, and early osteoarthritis in radiographs, and anterolateral labral tear, cartilage abnormality, and increased α-angle in MR arthrography.Imaging findings of femoroacetabular impingement syndrome: focusing on mixed-type impingementSuk-Joo Hong, Won Yong Shon, Chang Yoon Lee, Jae Sung Myung, Chang Ho Kang, Baek Hyun Kim10.1016/j.clinimag.2009.04.025Clinical Imaging 34, 2 (2010)2009-06-22Clinical Imaging2009-06-22342S0899-7071(10)X0002-XOriginal Articles116120http://www.clinicalimaging.org/article/PIIS0899707109000606/abstract?rss=yesAbstract: Objective: The purpose of this study is to investigate the characteristics of papillary thyroid carcinomas (PTCs) on color duplex sonography (CDUS).Methods: We retrospectively reviewed 115 nodules (104 patients) with PTC confirmed by pathology from February 1, 2005, to August 31, 2008. The size, border, calcification, echotexture, hemodynamics (peak systolic velocity and resistance index) of the thyroid nodules and cervical lymph nodes on CDUS were analyzed.Results: There was a close relationship between the size of the nodule and the vascularity of the thyroid carcinoma (P=.000). Microcalcification increased the suspicion for malignancy of the thyroid nodule. A hypoechoic thyroid nodule with abundant internal vascularity, ill-defined border and microcalcification was highly suggested PTC.Conclusion: CDUS plays an important role in the early detection of PTC and cervical lymph node metastasis, which would provide surgeons with valuable information for planning surgical intervention. Mastering manifestations of PTC on CDUS will improve the accuracy in the diagnosis of PTC.

Among these, pure cystic lesions and inadequate pathologic results were excluded. The remaining 530 solid thyroid nodules were analyzed by two radiologists. Each lesion was classified based on four sonographic features that suggested malignancy: microcalcifications; an irregular or microlobulated margin; marked hypoechogenicity; and a shape that was taller than wide. The sensitivity, specificity, positive predictive value, and negative predictive value of the each sonographic feature were calculated.Results: Final pathologic results showed that 97 (18.3%) of 530 nodules were malignant. The positive predictive values for malignancy in each sonographic feature were microcalcifications, 38.6% (39/101); an irregular or microlobulated margin, 28.2% (70/248); marked hypoechogenecity, 49.4% (38/77); taller than wide shape, 59.8% (49/82). In terms of relative risk, microcalcification [P<.01, relative risk (RR)=3.115, 95% CI: 1.724–5.628], hypoechogenecity (P<.01, RR=2.510, 95% CI: 1.290–4.881). The shape of nodule which was taller than wide (P<.01, RR=7.624, 95% CI: 4.156–13.986) revealed the highest predictive sonographic finding suggesting malignancy. However, margin is the least significant feature of detection of thyroid malignancy (P=.27, RR=1.395, 95% CI: 0.777–2.505).Conclusion: The three sonographic features of solid thyroid nodule, that is, microcalcifications, marked hypoechogenecity, and a taller than wide shape are meaningful findings in the diagnosis of thyroid malignancy. The shape that was taller than wide was the most reliable sonographic feature for predicting malignancy.Positive predictive values of sonographic features of solid thyroid noduleYoo Jin Hong, Eun Ju Son, Eun-Kyung Kim, Jin Young Kwak, Soon Won Hong, Hang-Seok Chang10.1016/j.clinimag.2008.10.034Clinical Imaging 34, 2 (2010)2009-09-14Clinical Imaging2009-09-14342S0899-7071(10)X0002-XOriginal Articles127133http://www.clinicalimaging.org/article/PIIS0899707109001247/abstract?rss=yesAbstract: Bilateral infarctions of the thalamus account for only a small fraction of ischemic strokes and carry a poor prognosis.

The aim of the “Dx-Direct” is not to present and describe all possible cardiovascular diseases but only the cases radiologists are most likely to see in their typical working day. All the books in the series discuss each condition or disease following the same format: Definitions (Epidemiology, Etiology), Imaging Signs, Clinical Aspects (Typical Presentation, Treatment Options, Course and Prognosis), Differential Diagnosis and key References. All sections are well balanced, easy and fast to read, with just the right level of detail. Since cardiac imaging has typically a multimodality approach, it is worthy of notice to begin each Imaging Sign section indicating the modality of choice which would allow the reader to reach the right diagnosis. Particularly valuable are the What Does the Clinician Want to Know and the Tips and Pitfalls Sections, presented at the end of each case, that discuss those aspects with simplicity, frequently introducing the main clinical data not to be forgotten by the radiologist. The key references are comprehensive and updated.Pietro Torricelli10.1016/j.clinimag.2009.12.006Clinical Imaging 34, 2 (2010)2010-01-25Clinical Imaging2010-01-25342S0899-7071(10)X0002-XBook Reviews158158http://www.clinicalimaging.org/article/PIIS0899707109003209/abstract?rss=yesIn the last decade, we have seen a diffusion and an exponential growth of diagnostic metabolic imaging by PET and PET/CT, particularly in oncology. This imaging modality has revolutionized and improved the management and sometimes the treatment of several pathologies, not only in oncology. The main reason for its success is that by PET we can image biological functions instead of anatomy. Consequently, nowadays, PET/CT in joining the morphological and functional imaging has, in many cases, replaced conventional CT as an essential diagnostic medium in managing patients with cancer, neurological diseases, and cardiovascular disorders.Eugenio Borsatti10.1016/j.clinimag.2009.12.004Clinical Imaging 34, 2 (2010)2010-01-25Clinical Imaging2010-01-25342S0899-7071(10)X0002-XBook Reviews158159http://www.clinicalimaging.org/article/PIIS0899707109003210/abstract?rss=yesIn this voluminous textbook, the objective of the authors is to help the readers, in particular the gastrointestinal radiologists facing problematic abdominal images, in reaching the correct diagnosis. The book is subdivided into five sections: the first one, “Advanced Modalities as Problem-Solving Tool,” discusses in four chapters the role of ultrasonography, multidetector computed tomography, magnetic resonance imaging, and positron emission tomography. The fifth chapter concludes this section with a very informative review of “A Multidimensional Approach to Abdominal Imaging.” Section 2, “Problem Solving: Disease Categories,” deals with localization and spread of disease; emphasizes the point that often the pathologic process is not localized to a specific organ and its origin may be removed from its present localization; and discusses the discovery by computed tomography of small incidentalomas, incidental asymptomatic lesions, and how to follow them. In “Imaging Evaluation of Acute Abdominal Pain,” the authors review the numerous possible causes and the related different diagnostic conclusions. The chapter “Imaging Evaluation of Trauma” presents the role of the different imaging procedures in the study of a trauma, wherever its location in the abdominal cavity. In “A Brief Guide to Cancer Imaging,” the staging and spread of malignant tumors involving the abdomen and pelvis are discussed. This section ends with a chapter dealing with common inherited and metabolic disorders.Antonio F.

The clinical presentation is that of a slowly progressive intra-orbital mass with variable degrees of exophthalmos. CT typically demonstrates the presence of a well-defined oval or rounded shaped mass but MRI provides superior evaluation of the orbit. The tumor is intra-conal in 80% of cases and usually shows TlW hypo-intensity, T2W hyperintensity and heterogeneous contrast enhancement that becomes more homogeneous on delayed imaging (5 minutes).Imaging features of cavernous hemangiomas of the orbit [in French]B.

This is magnified in the case of skin-sparing procedures where the margin is a much greater surface area and is the operation of choice in patients with diffuse microcalcifications and/or multifocal in situ disease. The objective of this study was to determine the efficacy of specimen radiographs of mastectomy in identifying occult carcinoma associated with microcalcifications and assessing the resection margins. We reviewed the histology and corresponding specimen radiographs of 16 patients with diffuse and widespread microcalcifications and who underwent skin-sparing mastectomy. After the specimens were serially sectioned, specimen radiographs of each section of the specimens were obtained with digital mammography equipment. Findings in the specimen radiographs were used to direct the histologic sampling of the specimens. On gross examination, two (12.5%) mastectomy specimens had identifiable discreet masses; the lesions were 4 and 7 mm, respectively. Histologic examination revealed the presence of carcinoma in 13 (81%) cases; seven with both infiltrating and in situ carcinoma and six with in situ carcinoma alone. The remaining three patients demonstrated only changes of biopsy site without any residual carcinoma. Microcalcifications were associated with in situ carcinoma in all malignant cases. Among the 12 cases with microcalcifications present at or within 2 mm of the margins, in situ carcinoma was present at the margins in three cases and located within 2 mm of the margins in two cases. All margins were negative in all cases with microcalcifications that were at least 1 cm away from the resection margins. The average number of tissue blocks examined was 16.6±5.4. The average number of tissue blocks sampled among randomly selected mastectomy specimens was 15.2±5.4. There was no statistically significant difference in the number of blocks between mastectomy cases with specimen radiographs taken and those without (t-test). Our study suggests that specimen radiographs may assist in identifying occult breast carcinoma associated with microcalcifications and assessing the resection margins without increased sampling.Specimen radiographs assist in identifying and assessing resection margins of occult breast carcinomasE.S.

CT-examinations of 1010 consecutive patients, all examined by 16-row MDCT of the abdomen over a time period of 20 months were retrospectively analyzed. All study patients were examined by triple phase CT (native, arterial and portal venous CT scan) of the abdomen and all received positive oral contrast prior to the examination. Thirty-three patients showed a juxtapapillary duodenal diverticulum, which could be seen on all CT scans, but usually was depicted most clearly on the thin collimated arterial phase CT images. Size of diverticula range from 4 mm to 4.5 cm (mean 1.7 cm). In 17 cases the diverticulum was located ventrally to the vaterian sphincter complex, extending less or more into the pancreas at the site where the dorsal and the ventral anlage of the pancreas have fused (type I). 12 diverticula were located dorsally to the sphincter complex (type II).Three patients presented with a bilobated juxtapapillary diverticulum extending to both sides, ventrally and dorsally (type III) and one patient showed a little diverticulum ventrally to the minor papilla (type IV).Three patients presented with food impaction in the diverticulum but only one of these patients with a large IPDD showed a Lemmel-syndrome, whereas the other three patients with non-calculous extrahepatic cholostasis showed larger diverticula without food impaction. MDCT allows to identify four different types of juxtapapillary duodenal diverticula and using the proposed classification may be helpful for a more exact, anatomy based radiological description of this CT finding.Juxtapapillary duodenal diverticula: MDCT findings in 1010 patients and proposal of a new classificationW.

We reviewed the sonographic findings of 21 patients with a final diagnosis of acute mesenteric ischemia (12 acute arterial forms and 9 acute venous forms). These examinations included identification of non peristaltic thin-walled fluid-filled intestinal loops (with or without pneumatosis), thickened intestinal wall (>3 mm) (noted as stratified or not), and preserved or absent mural flow assessed with color Doppler. Sonographic findings were compared with the surgical data (n=16) or with the clinical outcome (n=5).Color Doppler sonography of small bowel wall changes in 21 consecutive cases of acute mesenteric ischemiaE.M.
