Nuclear Medicine Scan

GI Bleed


This test detects and localizes bleeding sites in the stomach and bowels.

The Procedure:

  1. You will receive an injection in your hand or arm by the Nuclear Medicine Technologist. The injection is not a dye or contrast. The injection is a low level radioactive material and patients rarely have a reaction. If you are an inpatient, you may be injected through your existing INT or IV.
  2. The scan take approximately 2 hours to complete. You will be required to lie on your back for this scan.

Inpatient and Outpatient Preparation Instructions:

  1. If you are breastfeeding, pregnant or think you are pregnant you must inform your doctor.
  2. You are not to eat anything 4 hours before the test.
  3. Your stomach must be free of barium.


For your convenience we may schedule more than one test on the same day. This can be confusing because the test may have different preparation instructions. If you are an outpatient and don’t understand the instructions, please call Radiology. If you are an inpatient the nursing staff will correlate your test with the preparation.

For Your Information:

The Radiologist (x-ray) doctor will read the scan and send the results to your doctor.


There is a charge for the isotope injection, which must be ordered before the scan. If it is necessary to cancel the scan, please call the Radiology Department at (419) 394-3335, extension 3528 as soon as possible.
