Description
You are scheduled for a nuclear scan which involves the injection of a special material that contains minute amounts of radioactivity. The amount of radioactivity to which you will be exposed is less than for a chest X-ray. The radiologist in charge will take pictures (not X-rays) of the area under study. In your case we will be studying the kidneys. This test will help determine overall kidney function, especially comparing the right kidney to the left kidney, and will also show signs of blockage. At some time during the examination you will be given an injection of Lasix (a potent diuretic). This will cause the kidneys to make more urine and may, in some cases, cause a kidney to ache if there is obstruction. If this happens please let the radiologist know at the time and remind us on your return visit.
Possible risks
Other than minute amounts of radiation there are minimal risks with this procedure. With the dye injection there is a very small chance of an allergic reaction. A physician will be in attendance and will administer therapy if a reaction occurs.
Preparation
No restrictions of diet, fluids or medications exist for this examination.
