Forty-two consecutive patients who underwent abdominal CT without obvious renal abnormality at plain scanning were enrolled in this study. The renal perfusion scan was carried out using 16-slice spiral CT. The Pearson correlation coefficient was used to examine the correlation between perfusion parameter changes with aging.Results: In both the cortex and medulla, blood flow (BF) and blood volume (BV) were negatively correlated with age, while time-to-peak (TTP) value and mean transit time (MTT) showed a positive correlation with age. Changes in BF, TTP, and MTT were found to have a statistically significant correlation with age in both the cortex and medulla, while the correlation between BV and age showed no statistical significance.Conclusion: It is feasible to assess renal hemodynamics changes with aging in the elderly using the current clinically available CT perfusion imaging technology in vivo. It may be helpful in the management of aged patients to familiarize with the renal hemodynamics changes in clinical work-up.Renal hemodynamic changes with aging: a preliminary study using CT perfusion in the healthy elderlyHong Zhao, Jingshan Gong, Yan Wang, Zuoquan Zhang, Peixin Qin10.1016/j.clinimag.2009.06.031Clinical Imaging 34, 4 (2010)2009-11-09Clinical Imaging2009-11-09344S0899-7071(10)X0004-3Original Articles247250http://www.clinicalimaging.org/article/PIIS0899707108003689/abstract?rss=yesAbstract: In this paper, we describe two cases of anomalous origin of the left coronary artery and two cases of aneurysm on the left coronary artery.

It is critical to accurately fit the size and shape of the stent graft to the target region on the aorta. Proper sizing and shaping require the measurement of the orthogonal diameter of the target region from medical images. The present study aimed to acquire an accurate three-dimensional (3D) reconstruction of the aorta to determine the shape of the cross-sectional area where the stent graft would be implanted. A conventional geometric-active contour model was enhanced to prevent blurring and to improve edge detection with high noise resistivity. After the segmentation of two-dimensional (2D) images using the model, a 3D-reconstructed configuration of the aorta was achieved using a surface-rendering technique. The model could segment several selected synthetic images more accurately than conventional methods. Also, a 3D-reconstructed configuration of the abdominal aorta could be achieved using boundary coordinates extracted from 2D image segmentation. This preliminary study indicates the utility of the approach in optimizing stent graft configuration for AAA patients, thus enhancing stent graft healing.Determination of accurate stent graft configuration in abdominal aortic aneurysm using computed tomography: a preliminary studyHo Chul Kim, Sang Woo Park, Kyoung Won Nam, Hyuk Choi, Eun Jeong Choi, Seungoh Jin, Min Gi Kim, Kyung Sun10.1016/j.clinimag.2009.06.023Clinical Imaging 34, 4 (2010)2009-07-23Clinical Imaging2009-07-23344S0899-7071(10)X0004-3Original Articles255262http://www.clinicalimaging.org/article/PIIS0899707109001752/abstract?rss=yesAbstract: Purpose: The purpose of this study was to retrospectively evaluate the effect of various factors, including overall patient size, weight, and individual lesion characteristics, on the radiation dose and procedure time required to successfully perform computed tomography (CT)-guided liver lesion biopsies.Materials and Methods: This Institutional-Review-Board-approved study included 209 patients (average age, 59 years; range, 19–86 years; 105 males, 104 females) who underwent CT-guided liver lesion biopsy on a four-slice multidetector row CT scanner (LightSpeed Qx/i; GE Healthcare, Milwaukee, WI). Medical records and images were retrospectively reviewed to obtain the following data: (a) patient weight, (b) patient size, (c) lesion volume, (d) lesion depth, (e) CT dose index (CTDI) and effective radiation dose, and (f) procedure time. Statistical analysis was performed with multiple linear regression to assess the effect of various parameters on radiation dose and procedure time.Results: CTDI was significantly correlated with patient weight (P<.01), size (P=.03), and lesion volume (P<.01). The total effective radiation dose was significantly correlated with patient size (P<.01) and lesion depth (P<.01). Total procedure time was significantly correlated with lesion volume (P<.01) and depth (P<.01). There was a positive correlation between procedure time and effective radiation dose (r2=.57).Conclusion: In the current study, CT-guided liver lesion biopsy patient radiation dose was associated with both overall patient-specific features (weight and size) and specific lesion characteristics; however, the procedure duration was determined by lesion characteristics (lesion volume and depth) alone.CT-guided liver biopsy: correlation of procedure time and radiation dose with patient size, weight, and lesion volume and depthJianhai Li, Unni K.

Unfortunately, metastatic disease constitutes an absolute contraindication for surgery. Therefore, the detection of metastatic disease is a critical component of preoperative imaging of pancreatic adenocarcinoma. Computed tomography and magnetic resonance imaging are currently used for the preoperative evaluation of these patients. Positron emission tomography/computed tomography and ultrasonography may also be helpful in the detection of metastatic disease. This pictorial essay reviews the imaging findings of common and uncommon metastases from pancreatic adenocarcinoma.Pictorial essay: multimodality imaging of metastases from pancreatic ductal adenocarcinomaEfe Ozkan, Aparna Balachandran, Priya R.

Contrast-enhanced ultrasonography was performed on normal rabbit liver to observe the duration and intensity of enhancement.Results: The nanoscale ultrasound contrast agent had a good shape and uniform distribution by light microscope and transmission electron microscope, with average diameters of 623.4 nm and average zeta potential of 1.3 mV. The contrast imaging study in vivo showed that the nanoscale ultrasound contrast agent could significantly enhance the duration and echo intensity of the vessels and parenchyma in rabbit livers, and there were no obvious difference with micro-scale microbubbles.Conclusions: The nanoscale ultrasound contrast agent is stable and effective for the enhancement of ultrasound imaging. This study provides an important platform for miniaturizing and improving the targeting performance of ultrasound contrast agents.Preparation and characterization of a nanoscale ultrasound contrast agentDong Wang, Ke Yang, Yun-Hua Gao, Kai-Bin Tan, Zheng Liu10.1016/j.clinimag.2010.02.009Clinical Imaging 34, 4 (2010)2010-03-17Clinical Imaging2010-03-17344S0899-7071(10)X0004-3Original Articles288292http://www.clinicalimaging.org/article/PIIS0899707109001727/abstract?rss=yesAbstract: Nuclear magnetic resonance imaging has become a standard diagnostic procedure in clinical medicine and is well known to have hazards for patients with pacemaker or metallic foreign bodies. Compared to CT, the frequency of MRI examinations is increasing due to the missing exposure of the patients by X-rays. Furthermore, high-field magnetic resonance tomograph (MRT) with 3 T has entered clinical practice, and 7-T systems are installed in multiple scientific institutions. On the other hand, the possibility of burn injuries has been reported only in very few cases.Based on a clinical finding of a burn injury in a 31-year-old male patient during a routine MRI of the lumbar spine with standard protocol, the MR scanner was checked and the examination was simulated in an animal model.The patient received a third-degree burn injury of the skin of the right hand and pelvis in a small region of skin contact. The subsequent control of the MRI scanner indicated no abnormal values for radiofrequency (RF) and power. In the subsequent animal experiment, comparable injuries could only be obtained by high RF power in a microwave stove.It is concluded that ‘tissue loops’ resulting from a contact between hand and pelvis must be avoided. With regard to forensic aspects, the need to inform patients of such a minimal risk can be avoided if the patients are adequately positioned using an isolating material between the hands and pelvis. These facts must be emphasized more in the future, if high-field MRI with stronger RF gradients is available in routine imaging.Burn injury by nuclear magnetic resonance imagingErnst G.

Although a rib contusion could be depicted at (fat-suppressed) T2-weighted MRI, anatomical localization and assessment of lesion extent were superior and more straightforward at DWIBS. Thus, this report shows the utility of adding DWIBS to an MRI protocol for anterior chest wall evaluation.Diffusion-weighted whole-body imaging with background body signal suppression facilitates detection and evaluation of an anterior rib contusionThomas C.

Only three neonatal cases have been reported in the English-language literature. We present the clinical and multimodality imaging findings of a newborn with laceration and hemorrhage of a wandering spleen. The course was complicated by the concurrent diagnosis of glucose-6-phosphate dehydrogenase deficiency, which confused the clinical picture when a falling hematocrit raised the question of rebleeding several days after presentation.Multimodality imaging of a neonatal wandering spleenElizabeth Kagan Arleo, Arzu Kovanlikaya, Kevin Mennitt, Suchitra Acharya, Paula W.

However, plain films are still essential in the initial presentation and the follow up of these patients after corrective surgery. This book, authored by Drs. Yoo, MacDonald, and Babyn, provides a systematic approach to the interpretation of plain films in pediatric cardiac patients. It contains three main sections. The first section “Getting Started” covers the normal cardiovascular anatomy, a sequential segmental approach to congenital heart diseases and current surgical procedures with outstanding illustrations which are also accompanied by morphological photographs and state of the art cross sectional magnetic resonance images. There is also a chapter on how to obtain best chest radiographs with an emphasis on radiation protection.Arzu Kovanlikaya10.1016/j.clinimag.2010.04.011Clinical Imaging 34, 4 (2010)2010-05-31Clinical Imaging2010-05-31344S0899-7071(10)X0004-3Book Reviews320320http://www.clinicalimaging.org/article/PIIS0899707110000896/abstract?rss=yesThe book is primarily aimed at the cardiologists and radiologists, both in training and in practice. However, it will also be useful for cardiac surgeons and general practitioners as a reference text. The contributing authors represent a multidisciplinary group including cardiologists and radiologists. As the title suggests, the book reviews the various imaging modalities for diagnostic assessment of cardiovascular diseases with particular emphasis on computed tomography and magnetic resonance imaging. It elegantly combines the clinical aspects of cardiovascular disease with state of the art radiological methods of investigating them.Aamer Chugtal10.1016/j.clinimag.2010.04.012Clinical Imaging 34, 4 (2010)2010-05-31Clinical Imaging2010-05-31344S0899-7071(10)X0004-3Book Reviews320321http://www.clinicalimaging.org/article/PIIS0899707110000823/abstract?rss=yesThe title “Novel Techniques for Imaging the Heart: Cardiac MR and CT” belies the wealth of information in this book.

Current applications for liver pathology include two main directions. First, oncologic imaging, with detection; characterization and follow-up of lesions. Second, evaluation of diffuse liver diseases, including hepatic fibrosis. The diagnostic impact and role of diffusion-weighted MR imaging remain under investigation, but appear promising. Because of its short acquisition time, sensitivity, and additional information it provides, diffusion-weighted MR imaging should be included in routine liver imaging protocols.Difffusion-weighted MR imaging of liver pathology: principles and clinical applications [in French]M.

However, the presence of fat is not pathognomonic for dermoid cyst, and it may also be identified in immature teratomas, whose prognosis and treatment are different. Some imaging features are helpful to differentiate between both, rumors, including the presence of enhancement on CT and MRI.

This review article describes the clinicopathological features and imaging findings in patients with GCTTS. GCTTS usually presents as a soft tissue mass with pressure erosion of the underlying bone. Magnetic resonance (MR) imaging of GCTTS typically shows low to intermediate signal on T1- and T2-weighted spin-echo sequences due to the presence of haemosiderin, which exerts a paramagnetic effect. On gradient-echo sequences, the paramagnetic effect of haemosiderin is further exaggerated, resulting in areas of very low signal due to the blooming artefact. Ultrasonography shows a soft mass related to the tendon sheath that is hypervascular on colour or power Doppler imaging.Imaging of giant cell tumor of the tendon sheathJ.M.C. Wan, N.

CT findings of thymoma were analysed in 58 patients who had undergone surgery between January 2002 and September 2007. All cases were classified according to the Masaoka staging system. The presence of various CT findings was correlated with tumour invasiveness and recurrence. In statistical analysis, P<.05 was interpreted as significant.Computed tomography and thymoma: distinctive findings in invasive and noninvasive thymoma and predictive features of recurrenceA.M.
