What is Octreotide Scan?
An Octreotide Scan, also known as a Somatostatin Receptor Scintigraphy (SRS), is a diagnostic imaging procedure used to detect certain types of tumors in the body.
It works by employing a radioactive substance combined with a synthetic hormone called Octreotide, which attaches to receptors on tumor cells.
This allows healthcare providers to visualize and locate abnormal growths that express these receptors, such as neuroendocrine tumors (NETs).
Side Effects of Octreotide Scan
Octreotide Scans are generally safe, but like any medical procedure involving radiation, there are minimal risks. Some patients may experience mild discomfort or a temporary metallic taste in the mouth from the injection of the radioactive tracer.
Allergic reactions are rare but possible. Your healthcare team will discuss any specific concerns or considerations with you before the procedure.
How is Octreotide Scan Diagnosed?
Before the scan, you will receive an injection of Octreotide combined with a small amount of radioactive material. This tracer circulates through your bloodstream and binds to the receptors on tumor cells over a period of time (typically a few hours).
Once the tracer has had sufficient time to accumulate in the targeted areas, you will undergo imaging using a special camera that detects the radioactive signals emitted by the tracer. The procedure itself is painless, though you will need to lie still during the imaging process.
Potential Benefits of Octreotide Scan*
Octreotide Scans are valuable in diagnosing and staging neuroendocrine tumors, including those that may be difficult to detect using other imaging techniques. By identifying the location and extent of tumors, doctors can develop personalized treatment plans tailored to your specific condition. This scan plays a crucial role in managing and monitoring the progress of neuroendocrine tumors, helping to optimize treatment outcomes and improve patient care.
