Sometimes an ultrasound probe is put on the end of the endoscope to perform what is called an endoscopic ultrasound (EUS), which can be particularly useful for looking at gut-adjacent organs like the pancreas. Endoscopy can be used to visualize tumors in the lungs and gastrointestinal tract (stomach, small and large intestine and rectum). An endoscope is a flexible or rigid tube that has imaging capabilities and can enable small surgical procedures. EndoscopyĮndoscopy is a medical procedure that uses an endoscope to view the lining of multiple organs and tracts of the body. The scan detects neuroendocrine tumor cells that take up MIBG. A very small amount of a radioactive substance called MIBG is injected into a vein and travels through the bloodstream. MIBG scanĪn MIBG scan is used to find certain neuroendocrine tumors, such as pheochromocytoma and paraganglioma. FDG is most commonly used to detect tumors that are high grade and/or poorly differentiated. Cancer cells show up brighter in the picture because they are more active and take up more glucose than normal cells do. The PET scanner rotates around the body and makes a picture of where the body is using glucose. A small amount of FDG, a type of radioactive glucose (sugar), is injected into a vein.
FDG-PET scan (fluorodeoxyglucose-positron emission tomography scan)įDG-PET can find fast-growing neuroendocrine cancer cells for aggressive tumors. It’s 12.7-hour half-life allows Detectnet to be shipped throughout the US. In addition, less than 2% of study participants in clinical trials experienced adverse reactions to the agent, which typically included nausea, vomiting, and flushing.Īfter FDA approval, the CU 64 dotatate injection was immediately made available through nuclear pharmacies. and its commercial partner Curium, Detectnet is the first commercially available Cu 64 diagnostic agent on the U.S market.Īccording to phase 3 trials, Detectnet demonstrated clinical sensitivity to allow clinicians to develop more precise treatment approaches for their patients who have NETs. Diagnostic tracers like Cu 64 dotatate are used with PET scans and other functional imaging scans to improve how NETs are detected and staged.Īvailable under the commercial name Detectnet TM, the copper Cu 64 dotatate agent is a radiopharmaceutical tracer agent used in the localization of somatostatin receptor positive NETs in adults. Food and Drug Administration approved a copper Cu 64 dotatate injection for use in positron emission tomography (PET) scans for certain kinds of neuroendocrine tumors (NETs). The images clearly show NETs anywhere in the body. Following the injection of Ga-68 dotatate, patients undergo a PET scan.
PET with Ga-68 dotatate is a newer SRS test that uses a radioactive tracer called Ga-68 dotatate to bind to a tumor’s somatostatin receptors. Positron Emission Tomography (PET) is another type of scan that uses radioactive material and a special scanning device to detect neuroendocrine tumors. Octreotide attaches to the tumor, and a special camera that detects radioactivity shows where the tumors are in the body. Octreotide scanĪ very small amount of radioactive octreotide is injected into a vein and travels through the bloodstream. SRS can also help predict response to somatostatin analogs therapy as well as peptide receptor radionuclide therapy (PRRT).
NETSPOT PET HOW TO
Talk to your doctor about how to adjust your somatostatin analog before testing. Patients who take somatostatin analogs should discuss with their doctor the best timing for their exam as treatment can interfere with the test. Not all tumors have somatostatin receptors. Somatostatin Receptor Scintigraphy (SRS) is a type of radionuclide scan that uses a radioactive substance that can bind to a tumor’s somatostatin receptors and illuminate them. These images are very useful in contrasting different types of tissue as well as detecting abnormal growths such as tumors within the body. MRI uses radio waves, a powerful magnetic field, and a computer to generate detailed (2 or 3 dimensional) images of the body. A dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly. CT can generate images of different body tissues as well as help detect tumors. Computed Tomography (CT)ĬT is an imaging technique that uses a highly specialized X-Ray machine and computers to create multiple cross-sectional images of the body. Your doctor may use different scans than those used for other cancer types. It can sometimes be difficult to image NETs. Imaging tests are used to diagnose and assess neuroendocrine tumors.
