The purpose of the study was to show the value of combination of conventional MRI with DWI to raise the sensitivity and specificity considering the differentiation between pancreatic benign and malignant lesions.
Patients and Methods
Study included 30 patients performed in the radiology department, Cairo University, as well as in a private center: 21 males and 9 females. Age of patients ranged between 27 and 76 years.
The study was performed between August 2012 and April 2014. Patients were subjected to proper history taking, conventional MRI and DWI.
In our study using combined qualitative analysis of diffusion weighted imaging and quantitative analysis of ADC values we found that results of diffusion weighted MRI are approaching that of contrast enhanced MRI not only in detecting pancreatic tumors but also in detection of tumor necrosis and liver metastasis which are essential information to reflect disease prognosis and treatment strategies.

Combined qualitative and quantitative analysis of DWIs and ADC values respectively made the results of DW MRI approach that of contrast enhanced MRI not only in detection of pancreatic neoplasms but also in detection of tumor necrosis and liver metastasis. Using DWI in conjunction with conventional imaging as a useful modality aids in assessment of pancreatic neoplasms. In cases with contraindication to contrast administration DWI can be used as an alternative technique to contrast-enhanced imaging.
Assess sensitivity and specificity of DWI in differentiating benign from malignant lesions.
