Abstract
Utilization of mp-MRI Bosniak classification increases specificity and sensitivity for malignancy detection rate and results in category migrations which potentially affecting patient’s management and outcome. Our study demonstrated that mp-MRI can be utilized to confidently evaluate complex cystic renal masses, overcoming the traditional limitations of overlapping morphological imaging features. This prospective study was conducted on 94 patients with 113 cystic renal masses. Multiparametric MRI was successfully performed in all patients, revealing 30 cystic lesions to be Bosniak I, 25 cystic lesions to be Bosniak II, 22 cystic lesions be Bosniak IIf, 16 cystic lesions to be Bosniak III and 20 cystic lesions to be Bosniak IV. Pathological correlation that was accessible for 30 lesions, detected 28 malignant (12 clear cell RCC and 16 papillary RCC) and 2 benign lesions. Overall, in 11 lesions (18.96%) out of 58 cystic lesions (Bosniak IIF, III & IV), there were discrepancies in Bosniak category with mp-MRI compared to conventional MRI. This led to a superior category of classification of 10 lesions (17.2%) at mp-MRI in comparison to classification at Conventional MRI. However there was only one lesion downgraded from category IV to IIF. In all these lesions, the differences affect both classification and surgical outcome. This was probably because of its high contrast resolution. On the other hand, the mp-MR Imaging effect on diagnosing the complex cysts detected in the kidneys (and its clinical importance) still necessitates more evaluation MRI provided better evaluation of the inner characterization of the cyst due to its high-contrast resolution. The quantitative parameters derived from diffusion-weighted imaging, and contrast enhancement, can
