Sentinel Lymph Node Mapping

Since 1998, IntraMedical Imaging has provided cancer detecting imaging tools to operating rooms. It all started with sentinel lymph node mapping; a surgical technique used to determine the stage of cancers. It also shows whether cancer has spread to determine the patient's best treatment options. A radiopharmaceutical is injected near the tumor, to help find where it is draining from sentinel lymph nodes. The sentinel lymph nodes are removed by the surgeon and sent to a pathologist for cancer screening.


Our node seeker gamma probe is two times more sensitive than the NeoProbe and does a superior job of identifying unhealthy tissues. IntraMedical Imaging offers two probes that can be employed in the node seeker; sentinel lymph node biopsy and node biopsy/mapping in cervical, prostate, and gastric cancer. Sentinel lymph node mapping is what started the use of molecular imaging to detect the onset and spread of cancer. It is 90% accurate in detecting cancerous lymph nodes.


Sentinel lymph node mapping can be done the day before, or the day of your biopsy. You sit in a recliner for about twenty minutes or so, while a doctor or nurse injects a small amount of radioactive liquid below the skin. The injection is just for tracing. The probe is capable of measuring how much of the liquid was absorbed. The final test results are usually given within five working days. The main job of the lymphatic system is to help the body fight infection. Sentinel lymph node mapping is not harmful to the immune system.


Sentinel lymph node mapping is done on patients who have already been diagnosed with cancer, usually breast cancer, or melanoma. It can also determine the stage of penile cancer and endometrial cancer. Sentinel lymph node mapping helps doctors avoid removing too many lymph nodes at once, which can cause some pretty serious side effects. A patient typically has one to five sentinel lymph nodes, all of which should be identified and removed. Melanoma patients who undergo sentinel lymph node mapping can avoid more surgery if test results come back negative.


After the procedure, you might have pain around the site for about two weeks; mild painkillers can help. You may also feel tight and stiff in the area for about six weeks. Sometimes blood collects in the surrounding tissues. It can go away on its own in a few months or be drained by your doctor or nurse. Sentinel lymph node mapping is a generally safe procedure with very mild side effects.


Products like ours help doctors quickly and effectively find the location and extent of certain cancers in real-time. They are based on positron emission topography power. Tumors appear as 'hot spots' if they retain fluorodeoxyglucose, the radiopharmaceutical used during sentinel lymph node mapping. In breast cancer, sentinel lymph nodes are usually found under the arm. Other lymph nodes can be found elsewhere in the lymphatic system of the breast.
