Lymphoscintigraphy (Sentinel Node Study)

Your physician has requested that you have a lymphoscintigraphy (Sentinel Node Study). This is a safe, simple way to evaluate the lymphatic drainage within your body. The material injected consists of Technetium-99m-Sulfur Colloid (Tc99m-SC). The radioactivity associated with the injection of Technetium-99m - (Sulfur Colloid) is negligible. The injection will not make you feel dizzy, nauseated, hot or cold. All injections for these examinations are performed by a Radiologist.

Extremity Lymphoscintigraphy

When evaluating the lymphatic system of an extremity, injections are made within the skin web between the digits of the upper/lower extremities, as required. Images are taken over the following few hours to determine the lymphatic drainage pattern of the area affected. Local anesthesia is not required, since the injections are made using very small needles and the radiopharmaceutical is administered just under the skin (subcutaneous), similar to when a tuberculin (TB) skin test is administered. Images may take a few hours.

Breast Lymphoscintigraphy

When evaluating the breast lymphatic drainage prior to surgery, injections are made just under the skin (subcutaneous) around the affected breast's areola and/or within the breast tumor itself, as directed by your surgeon. This will be done on the morning, prior to your surgery or the afternoon for next day surgery. Local anesthesia is not required, since the injections are made using very small needles and the radiopharmaceutical is administered just under the skin (subcutaneous), similar to when a tuberculin (TB) skin test is administered. A single 10 minute image of your chest will be obtained 30 minutes after injection.

Melanoma Lymphoscintigraphy

When evaluating the lymphatic drainage prior to surgery, an injection(s) is made just under the skin (subcutaneous) around the affected part of the body where the melanoma is located, as directed by your surgeon. This will be done prior to your surgery. Local anesthesia is not required, since the injections are made using very small needles and the radiopharmaceutical is administered just under the skin (subcutaneous), similar to when a tuberculin (TB) skin test is administered. Images of the affected part of the body may be obtained for up to 4 hours after the injection.

To outline our requirements, you will:

  1. After registration report to Medical Imaging and check in with our receptionist.
  2. You will then be escorted to an imaging room where the injection will be performed by a Radiologist.
  3. After the injection you will be escorted to Nuclear Medicine, where you will be positioned on the Nuclear Medicine camera.
  4. The required images will be obtained, as outlined above.
  5. The Radiologist will review the images before you may be released from the department.

Note: Inpatients will be transported to Nuclear Medicine.

If your surgery is the day of this study you will report to ambulatory surgery to check-in. From ambulatory surgery you will be transported to medical imaging for this test. Once the injection and subsequent imaging is complete you will be transported back to ambulatory surgery.
