Abstract:Objective To compare the application effects of 3 dimensional sampling perfertion with
application optimized contrasts using different flip angle evolutions (3D-SPACE) sequence under the
status of high-resolution and low-resolution in Magnetic Resonance Cholangiopancreatography (MRCP)
examination. Methods Fortyfour
examinees were conducted MRCP scanning with Siemens Avanto 1.5T
magnetic resonance imaging (MRI) scanner. In such examination, examinees were scanned by adopting
3DSPACE
sequence with highresolution
and lowresolution
mode respectively. Then the imaging
effects in the two resolution models were evaluated and scored by two senior radiologists separately.
Later, the scoring results were analyzed statistically with the Wilcoxon rank sum test. Results Minimal
changes were displayed more clearly in original image with highresolution
3DSPACE
sequence, whilst
imaging time of lowresolution
3DSPACE
sequence was less. There was no significant difference
in image quality with Maximum Intensity Projection (MIP) reconstruction technology between the
two resolution models (score difference in delineating common bile duct: P=0.899, score difference
in delineating right and left hepatic duct as well as main pancreatic duct: P=0.623). Conclusion For
examinees with poor cooperation, low-resolution 3D-SPACE sequence was easier to get qualified images.
