An octreotide scan is a type of SPECT scintigraphy used to find carcinoid, pancreatic neuroendocrine tumors, and to localize sarcoidosis. It is also called somatostatin receptor scintigraphy (SRS). Octreotide , a drug similar to somatostatin , is radiolabeled with indium-111 , [ 1 ] and is injected into a vein and travels through the bloodstream.
The Krenning score [1] is used to grade the uptake intensity of neuroendocrine tumors on somatostatin receptor imaging such as octreotide scan. [further explanation needed] Typically, peptide receptor radionuclide therapy (PRRT) is considered when the Krenning score is greater than 2.

Octreotide is a synthetic modification of somatostatin with a longer half-life. [ citation needed ] OctreoScan, also called somatostatin receptor scintigraphy (SRS or SSRS), utilizes intravenously administered octreotide that is chemically bound to a radioactive substance, often indium -111, to detect larger lesions with tumor cells that are ...
An imaging phantom for determining CT performance Imaging phantom as seen on a medical ultrasound machine.. Imaging phantom, or simply phantom, is a specially designed object that is scanned or imaged in the field of medical imaging to evaluate, analyze, and tune the performance of various imaging devices.

Molecular imaging is a field of medical imaging that focuses on imaging molecules of medical interest within living patients. This is in contrast to conventional methods for obtaining molecular information from preserved tissue samples, such as histology.
Medical optical imaging is the use of light as an investigational imaging technique for medical applications, pioneered by American Physical Chemist Britton Chance.Examples include optical microscopy, spectroscopy, endoscopy, scanning laser ophthalmoscopy, laser Doppler imaging, and optical coherence tomography.
