Abstract

Background: Despite the fact that many fortuitous lesions have little metastatic potential, cross-sectional imaging is improving the diagnosis of renal tumors.
Purpose: To assess the role of multiparametric magnetic resonance imaging (mpMRI) in the assessment of different renal masses.
Patients and Methods: This was a cross-sectional study performed in in Benha university hospitals and was conducted on thirty eight patients having renal masses previously diagnosed with ultrasound and/or computed tomography, referred to the radiology, urology and oncology departments. All patients were subjected to full history taking, radiological examination including contrast enhanced MRI of the abdomen & pelvis and histopathological correlation of surgical specimens.
Results: The percentage of benign and malignant cystic masses was 37%, whereas the percentage of benign and malignant solid masses was 63%. At b0 and b1000 s/mm2, there was a significant statistical difference (p > 0.05) between the mean Analog to Digital Conversion (ADC) values of benign and malignant solid renal masses. Furthermore, at b0 s/mm2, there was a statistically significant difference (p >0.01) between the mean ADC values of benign and malignant cystic renal masses, and a statistically significant difference (p >0.05) between the mean ADC values of benign and malignant cystic renal masses at b1000 s/mm2.
Conclusion: We confirmed the optimal diagnostic performance of mpMRI to identify benign and RCC in all clinical stages.
