Abstract

AIM: To compare the efficiency of the different MR sequences i n the diagnosis of pancreatic adenocarcinomas and to assess the MRI findings.

METHODS: 70 patients with pancreatic adenocarcinoma proved by surgically or clinically underwent MR imaging with a 1.5 T superconducting unit. MR imaging sequences included T1WI, T2WI, fat-suppressed T1WI, dynamic FMPSPGR and delayed contrast-enhanced T1WI. The MR images were viewed. We analyzed of the quality and quanty MR sequences.

RESULTS: The tumors could be seen more clearly on FT1WI and 72 .22% appeared as obvious hypointense. FT1WI was the most effective sequence in the detection of small non-contour-deforming pancreatic carcinoma. Dynamic FMPSPGR and delayed contrast-enhanced T1WI were more sensitive sequences in the demonstration of dilated biliary ducts. Blood vessels around pancreas could be shown distinctly on dynamic FMPSPGR. Metastasis of retroperitoneal lymph no des could be defined clearly on T1WI. T2WI was the most sensitive sequence in the display of liver metastasis. MRCP was very useful for obstructive jaundice.

CONCLUSION: MR images are useful in the diagnosis of pancreatic adenocarcinomas.
