How does single photon emission computed tomography work?
At its most basic level, SPECT produces a 3-dimensional image of the distribution of a radioactive tracer (sometimes called a probe) injected into the bloodstream and subsequently taken up by certain tissues. [1] This is accomplished via the use of specialized nuclear medicine cameras..
What is the basic principle of SPECT?
SPECT takes conventional two-dimensional nuclear medicine images acquired at different views around the patient and provides an estimate of the three-dimensional radioactivity distribution using methods of image reconstruction from multiple projections..
What is the difference between a CT scan and a SPECT CT scan?
A SPECT scan is a type of nuclear medicine test that uses a radiotracer (a special contrast agent), that is injected through your vein.
A CT scan uses X-ray radiation to provide thorough images of the structures inside your body (anatomy)..
What is the purpose of a 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..
What is the purpose of single photon emission computerized tomography?
A single-photon emission computerized tomography (SPECT) scan lets your doctor analyze your body's organs, tissue and bones.
A SPECT scan is a type of nuclear imaging test, which means it uses a radioactive substance and a special camera to create .

Why single photon is used in SPECT?
Single-photon emission computed tomography (SPECT) is a nuclear imaging modality used frequently in diagnostic medicine.
It allows the clinician to assess the perfusion and functionality of specific tissues..
- 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 .- D information
- The main advantage of SPECT is the ability to view the reconstructed image in multiple planes and to separate overlapping structures.
As much as a sixfold increase in image contrast can be obtained with SPECT.
