Lymphoscintigraphy/Sentinel Node Imaging
Lymphoscintigraphy or Sentinel Node imaging allows lymphatic drainage pathways from the site of primary tumors to be seen. It also aids in finding out which lymph nodes may have metastatic cancer involvement.
What to Expect
- The patient will come in and be situated on the table comfortably and the site of the tumor will be exposed.
- The radiologist or surgeon will inject small amounts of radioactive isotope around the tumor.
- If the tumor is melanoma, we will take pictures for up to 1 hour and then the patient will go to surgery.
- If the tumor is breast cancer, after the injections the patient will go to surgery.
- This test may take up to 2 hours.
