About the Test
Your doctor has ordered a renal scan with lasix. The renal scan portion of the test shows the size, shape, and function of your kidneys. Sometimes when kidney function is decreased, the doctor wants to know if the kidneys respond to a diuretic. The lasix portion of the test measures this response.
Your total test time is about 2 hours. The amount of radiation used in this test is small, and well within limits that are safe.
Preparation for the Test
There is no preparation for the test.
Please come to the Nuclear Medicine Reception Desk, Room 8-148 in the Galter Pavilion, 201 E. Huron at your scheduled appointment time.
If you have any questions about this test, please call the Nuclear Medicine Department at 312-926-2514, Monday-Friday, 7:30 am-5:00 pm.
During the Test
When you arrive in the Nuclear Medicine Department, a doctor will ask you questions about your medical history. You will then be asked to lie on a table and will be given an intravenous (into the vein) injection of a radioactive tracer. If you think you might be pregnant, please inform the technologist (tech) before you are given any injection.
Pictures of your kidneys and bladder will be taken continuously for 30 minutes. At the end of 30 minutes the tech will ask you to empty your bladder. You will be asked to sit in front of the camera and one more picture of your kidneys and bladder will be taken. After this picture, a doctor will give you an injection of lasix. Pictures of your kidneys and bladder will again be taken continuously for 30 minutes.
At the end of 30 minutes the tech will ask you to empty your bladder. You will be asked to sit in front of the camera and one more picture of your kidneys and bladder will be taken. Before you leave the department, the doctor will review your renal scan.
