Information and Preparation Instructions
Please arrive in the Radiology department for the admissions process. A nuclear medicine technologist will greet you for the appointment. A small intravenous (I.V.) line will be started by the technologist for the exam. You will be lying on your back for 40 minutes for the images. Please wear loose, warm, comfortable clothing. The technologist will inject a radioactive tracer through the I.V. and images begin immediately. The radiotracer will not cause any allergic reaction or discomfort. At 20 minutes, the technologist will administer a diuretic (lasix) to flush out the kidneys (unless otherwise requested by the physician). Images will continue for 20 more minutes or until you can no longer tolerate a full bladder.
Before Your Renogram
- Drink 500 mL or 16 oz. of fluid prior to the exam
