Abstract
Different sequences of MRCP protocol have been introduced over the years. MRCP is currently replacing the ERCP so we can avoid this invasive technique. Many studies were done on the MRCP study using different sequences. Many studies also used different scoring systems to evaluate the ducts and the motion artifacts. Few of the studies used the 3D isotropic T2 sequence in their evaluation and none of them were done on the MRCP.
Our aim was to evaluate the role and the added value of this sequence in the accurate diagnosis, so we started adding it to the MRCP protocol.
Our study was done including 100 patients complaining of biliary manifestations as biliary obstruction as jaundice, itching and changes in the color of the stools who were sent to the department of radiodiagnosis to do MRCP study.
We used a scoring system for the motion artifacts where 1 stands for image is not diagnostic due to artifacts, 2 for image has major artifacts 3 for image has minor artifacts and 4 for image has no artifacts.
Another scoring system was also used, which was done by examining and dividing the biliary tree into segments; IHD, CHD, CD, proximal and distal CBD as well as examining the pancreatic duct. Based on 4 points’ scoring system, the evaluation was done where 0 stands for non-visualized duct, 1 for visible but not diagnostic, 2 for visible and diagnostic and 3 for excellent visualization
The image artifacts in the 3D isotropic sequence images were statistically lower than the 3D heavily weighted images (P<0.01, statistically significant if the P<0.05). Also, the ducts visibility on the 3D isotropic sequence was statistically better than the other sequence (P<0.01, statistically significant if the P<0.05).
