Protocol: Dynamic images are acquired by placing the detector Posteriorly over KUB region, immediately after the injection of 5mCi of 99m Tc EC. Patient is injected with Inj. Lasix just before the Radiopharmaceutical administration. Perfusion Images: Left Kidney: There is evidence of delayed and reduced perfusion in this kidney. Right Kidney: There is evidence of normal perfusion in this kidney. Dynamic Images: Left Kidney: Left kidney is enlarged in size. It shows delayed and reduced cortical radiotracer uptake. There is delayed intra-renal cortico-calyceal transit noted through this kidney. There is evidence of a large photopenic area medially which corresponds to dilated pelvi-calyceal system. It shows progressive radiotracer accumulation with no further drainage Right Kidney: Right kidney is normal in size, shape and location. It shows normal cortical radiotracer uptake. There is normal intra-renal cortico-calyceal transit noted through this kidney. There is evidence of normal and progressive radiotracer drainage through this kidney.
