Sentinel Scintigraphy in Chennai
What is this study?
Sentinel scintigraphy is a nuclear medicine imaging technique used to identify sentinel lymph nodes, which are the first lymph nodes to receive drainage from a tumor site.
What is the need for the study?
The study is needed to assist in the staging and treatment planning of certain cancers, particularly breast cancer and melanoma, by identifying sentinel lymph nodes for biopsy or surgical removal.
How do I prepare?
Preparation for sentinel scintigraphy may involve injection of a radioactive tracer and waiting for a period before imaging. Your healthcare provider will provide specific instructions based on your individual circumstances.
How is this scan performed?
During the scan, a radioactive tracer is injected near the tumor site. The tracer travels through the lymphatic system to the sentinel lymph nodes, which are then visualized using a gamma camera.
What should I do after the scan?
After the scan, you can resume normal activities. Your healthcare provider will discuss the results of the scan with you and any further steps, such as biopsy or surgery, during a follow-up appointment.
Are there any risks in the study?
Sentinel scintigraphy is generally considered safe, with minimal risk associated with the radioactive tracer. Your healthcare provider will discuss any potential risks with you before the procedure.
