What is single photon emission computed tomography imaging of dopamine transporter is useful for?

Dopamine transporter (DAT) single-photon emission computed tomography (SPECT) contributes to the diagnosis of PD and Lewy body dementia by providing a SPECT image reflecting the DAT distribution density in the striatum..

What is SPET in radiography?

Single-photon emission computed tomography (SPECT, or less commonly, SPET) is a nuclear medicine tomographic imaging technique using gamma rays.
It is very similar to conventional nuclear medicine planar imaging using a gamma camera (that is, scintigraphy), but is able to provide true .

What is the mechanism of single photon emission computed tomography?

How does a SPECT scan work? A small amount of radioactive tracer is injected into your bloodstream.
Inside your body, the tracer produces a type of energy called gamma rays.
A gamma camera picks up signals from the tracer, and a computer converts them into pictures of blood flow through your heart..

What is the SPECT scan used for?

A single-photon emission computerized tomography (SPECT) scan lets your doctor analyze your body's organs, tissue and bones.
