This is the routine right (%) versus left (%) renal function study. It is the preferred general function study in patients with serum creatinine value < 4 mgm %. These conditions include: vascular, renal, and collecting system diseases of many etiologies

This examination is most commonly performed for patients with suspected reflux of urine from the bladder into the ureters. The sensitivity of this examination and the identification of ureteral reflux is equal to the radiographic equivalent with far less (about one-one hundredth) of the radiation burden of the radiologic evaluation

The scan is designed to differentiate dilated renal collecting systems (calyces, pelves, or ureters) from obstructed collecting systems. The site and side of the questioned obstruction must be provided prior to scheduling the study. Without it the test cannot be performed. The test might also be invalid if there is impaired renal function on the affected side, or if there is vesicoureteric reflux. In these patients, a decision must be made to increase furosemide or place an indwelling catheter

This test is to determine the presence of normal functioning renal tissue. Use static pinhole protocol for children and adults. Additional SPECT images may be requested after planars. Usual indications include

Nuclear Medicine Lasix Renal Scan should be scheduled before other CT or MRI studies if using contrast.
