Abstract In summary, MRI plays an important role in the diagnosis of different pancreatic lesions, MRI is a good image quality for soft tissue contrast and has a higher safety profile of intravascular contrast media. Diffusion weighted image (DWI) is an imaging technique that is sensitive to water diffusion in living tissue, we can measure the apparent diffusion coefficient (ADC) in a given tissue to differentiate between benign and malignant pancreatic tumors. This study was designed to assess the role of MRI study including diffusion weighted imaging (DWI) & dynamic contrast enhancement in the evaluation of different pancreatic lesions. Twenty patients with 23 pancreatic lesions were examined in our study by MRI. The results of imaging techniques were compared to laboratory investigations and pathological data. Our study included 5 pancreatitis lesions, 8 pancreatic cystic lesions, one case of focal pancreatitis & 9 patients had adenocarcinoma. MRI enabled us to assess the neoplastic pancreatic lesions with accurate detection of extension, vascular encasement, nodal involvement and hepatic metastatic lesions. DWI and ADC values were significant methods to differentiate between our study subgroups and control group; (p<0.001). Dynamic contrast study and time intensity curve enable us to differentiate between focal pancreatitis and adenocarcinoma. Summary & Conclusions . |
