Abstract
Recently, a growing number of renal masses detected is noted, a lot of which as an incidental finding due to the increase in the use of cross-sectional imaging. This increased detection needed the development of a tool for the differentiation of neoplastic from non-neoplastic lesions as well as for the differentiation between benign and malignant lesions.
The development of new reliable imaging criteria, capable of accurately differentiating between the different types of renal tumors as well as differentiating between indolent and more aggressive malignant lesions, would be beneficial in reducing the number of unnecessary biopsies, in considering the most suitable treatment strategy for a tumor, and in promoting active surveillance in eligible patients using imaging follow-up.
Over the last two decades, marked advances in MRI techniques have been made with resultant improvement in the quality of the images and spatial coverage. Multiparametric MRI could potentially offer histological and anatomical information before the therapeutic intervention, negating the need for biopsy or more imaging; this is due to its excellent soft-tissue contrast as well as a combination of qualitative, semi-quantitative, and quantitative features. Adding exogenous contrast, in addition to the magnetic resonance inherent soft tissue contrast properties, can allow for additional tissue characterization refinements.
This work aimed to study the role of Multiparametric Magnetic Resonance Imaging (mpMRI) in the characterization of solid renal masses.
