Comprehension: Kidney MRI with Contrast
Study the coronal and axial MRI sections of the kidneys following the injection of intravenous contrast material. The renal cortices as well as columns are opacified. The renal pyramids stand out between these structures. In the axial section, the left renal vein is seen between the aorta and proximal superior mesenteric artery. Note the prominent retroperitoneal fat around the kidneys in the coronal section. The left kidney appears smaller than the right because the kidneys were not in the same antero-posterior position in this plane.
