Throat (Laryngeal/Pharyngeal) Cancers

What is Gamma Camera/SPECT?
SPECT scan is used to analyse the functions of the internal organs. A SPECT scan is a type of nuclear imaging test, which uses a radioactive substance and a special camera to create 2D/3D images. For instance, CT scan can give information on percentage blockages of different vessels supplying the heart, and a SPECT scan can show how blood flows to the heart.
SPECT SCAN
A single photon emission computed tomography (SPECT) scan is an imaging test that shows how blood flows to tissues and organs. It may be used to help diagnose seizures, stroke, stress fractures, infections, and tumors in the spine.

Cardiology:	The functioning of the heart muscle is examined in cardiology - myocardial perfusion imaging (mpi; ischemic heart disease), metabolism of the myocardium. The examination has two parts - before and after physical exercise. The lungs or the venous system can be examined, too.
Neurology:	The blood circulation in the brain is examined in neurology. It can localize the afflicted area and help diagnose the disease (dementia, Alzheimer’s disease, Parkinson’s disease). It can also find the exact place where an operation of the brain could be done (epilepsy - double examination - before and during the seizure)
Oncology:	SPECT helps with the localization of tumors. It is used during lymphoscintigraphy, examination of the sentinel nodes, etc. Other changes of metabolism Localization of inflammation, injury or joint disease.
