| Abstract Background: In the last decade, the incidence of renal cell carcinoma (RCC) has been rising, with the greatest increase observed for solid tumors. Magnetic resonance imaging (MRI) protocols and algorithms have recently been available for classifying RCC subtypes and benign subtypes. Purpose: To assess the role of multi-parametric magnetic resonance imaging (mpMRI) in differentiation of different types of solid renal masses. Patients and Methods: This is a cross-sectional prospective study performed in Al- Imamian Al- Kadhmain medical city and was conducted on 41 patients having renal masses previously diagnosed with ultrasound and/or computed tomography, referred to the radiology department. All patients were subjected to full history taking, radiological examination inform of mpMRI of the upper abdomen and histopathological correlation of surgical specimens. Results: malignant solid renal mass lesion are commoner than benign masses. Lesions that shows low signal intensity on T2WI (lipid poor AML and papillary RCC), high to intermediate T2WI seen in other types of solid renal masses, in phase opposed phase T1WI was very helpful in identifying the fat content of different types of solid renal masses. The mean ADC value of malignant lesions was very helpful in this study it was significantly lower than that of benign. Dynamic contrast MRI showed three types of curves: progressive, plateau and washout dynamic curves. Conclusion: Multiparametric MR imaging as a noninvasive imaging method provides critical information that can help in differentiation of the most common solid renal masses, T2WI play an important role in differentiation between different types of solid renal masses and narrow the differential diagnosis. | ||
