Fig 2 shows normal volunteer's image obtained by using turbo-spin echo. Non-dilated intra and extrahepatic bile duct are well documented, also normal pancreatic duct can be seen. Turbo spin echo technique is good for the visualization of normal bile duct and pancreatic duct. However bowel fluid is also displayed simultanechsly which overlap the biliary images. On the other hard, PSIF sequence does not display bowel fluid, because of the peristatic movement.
PSIF sequence is very sensitive for movemnt.
On PSIF sequence, bowel fluid does not disturb for the visualization of biliary and pancreatic duct. Fig3A shows the 3D-MRC of patient with reuvwence of bile duct cancer after operation. Fig4 shows the image of pancreatic head cancer. Presenting the dilatation of biliary and pancreatic duct. Strictures of bile duct and pancreatic duct are documented well.
