WebReninoma is a tumor of the renal juxtaglomerular cell apparatus that causes hypertension and hypokalemia via hypersecretion of renin. 27 It is a single, well-defined, poorly enhanced ovoid mass on CT scan, and its typical clinical manifestations contribute to the final diagnosis. Conclusion WebDiffusion weighted imaging (DWI) constitutes a major functional parameter performed in Magnetic Resonance Imaging (MRI). The DW sequence is performed by acquiring a set of native images described by their b-values, each b-value representing the strength of the diffusion MR gradients specific to that sequence. By fitting the data with models …
