Abstract
Objective
To investigate value of magnetic resonance cholangiopancreatography (MRCP) using oral
diluted gadolinium (Gd)-diethylenetriamine penta-acetic acid (DTPA) as negative contrast
materials in diagnosis of juxtapapillary duodenal diverticulum with atypical imaging
features.
Methods
Nineteen patients with juxtapapillary duodenal diverticula of which imaging findings
were atypical underwent MRCP using oral diluted Gd-DTPA as negative contrast materials
after conventional MRCP without any oral contrast materials.
Results
Twenty diverticula were revealed in the 19 patients. At conventional MRCP, the diverticula
appeared as rounded lesion with high signal intensity. After oral administration of
diluted Gd-DTPA, they disappeared at MRCP. These entities were diagnosed as duodenal
diverticula for they communicate with duodenal lumen.
Conclusion
MRCP using oral Gd-DTPA as negative contrast materials can be helpful in obtaining
definitive diagnosis of those juxtapapillary duodenal diverticula without typical
imaging features.
