25. Somatostatin Receptor Scintigraphy (SRS)
If your doctor finds your tests concerning, he or she may perform a test called somatostatin receptor scintigraphy (SRS), which shows where the cancerous cells are hiding out in your body. While it doesn’t work for all tumors, it can be extremely helpful in identifying some of them. You doctor will inject a mixture of octreotide and a radioactive material into the blood stream. After a few hours, your doctor can see the cancerous cells using a specially designed camera. This helps your doctor determine the progression of the cancer as well as the next course of action.
