Objectives: To assess the efficacy of MR imaging, with MR Cholangiography and MR Angiography in pre operative evaluation of pancreatic tumors.
Materials and Methods: 30 patients suspected of having pancreatic tumors underwent MR imaging with a 1.5T unit. Images were prospectively analyzed results correlated with surgery and biopsy.
Results: Of the total 30 patients, 24 were histologically proven to be malignant of which 21 underwent surgery. MR characterization - benign from malignant lesions resulted in 27 correct diagnosis (accuracy 90%). 2 patients with histologically confirmed chronic pancreatitis were wrongly considered malignant. Among patients with histologically proven malignancy (n=24), MR imaging yielded correct diagnosis in 23 of 24 patients a sensitivity of 96 %. Overall accuracy for determining vascular involvement in patients who underwent surgery (n=21) was 86% (18 out of 21) a sensitivity of 75% (6 of 8). Sensitivity for detection of lymphadenopathy and liver metastasis was only 50% and 60% respectively. Among patients with final diagnosis of malignancy (n=24) who underwent surgery (n=21), overall accuracy for determining tumor nonresectabilty was 81 % (17 out of 21).
Conclusion: A comprehensive combination of MR imaging sequences with MRCP and MR Angiography offers excellent potential to depict, characterize and preoperatively determine the resectability of pancreatic masses. |
