Lasix renal scan washout time. loss of filtration function in left kidney, 20% loss of filtration function in right kidney. Lasix wash-out half time - right kidney: 24 minutes, left kidney: 46 min. (Abnormal atrophic left kidney with decreased flow and function, fairly normal right renal blood flow and function.) kidney(abnormal 2) image 1 image 2 image 3 image 4 Clinical Indication: 55 year old white female - dynamic renal scan. Dose: 10mCi Tc-99m-glucoheptonate given i.v. Results: decreased blood flow to both kidneys, decreased function both kidneys. Excretion images: revealed multiple photopenic areas within the kidneys that filled w radiotracer. Lasix wash-out slow - 37 minutes.
