Abstract Objective: To evaluate the value of MR dynamic Gadolinium-enhanced fast multiplanar spoiled gradient-echo (FMPSPGR) and spin-echo (SE) T1-weighted fat-suppressed techniques in the diagnosis of pancreatic carcinoma.
Methods: Eighteen cases of pancreatic carcinoma veri-fied by surgical and pathologic results were examined by MR, and the MR sequences included SE T1WI, FSE T2WI, SE T1-weighted fat-suppressed and dynamic Gadolinium-enhanced FMPSPGR.
Results: Of 18 pancreatic carcinomas, 10, 6, and 2 tumors showed respectively hypo-intensity, iso-intensity and hyper-intensity on SE T1WI, meanwhile, 8, 6, and 4 tumors displayed hyper-intensity, iso-intensity and hypo-intensity on FSE T2WI in comparison with the normal pancreatic tissue. All of the tumors showed hypo-intensity on SE T1-weighted fat-suppressed and also obvious non-enhancement or slight enhancement on MR dynamic Gadolinium-enhanced FMPSPGR images during the arterial dominant phase scanning.
Conclusion: SE T1-weighted fat-suppressed and MR dynamic Gadolinium-enhanced FMPSPGR sequences could evidently improve the sensitivity and specificity in the diagnosis of pancreatic carcinoma.
