What is the use of spect (single-photon emission computed tomography) in nuclear medicine?

3D imaging: Spect is a technique that allows 3d imaging of nuclear medicine scans, giving better spatial resolution (ie, smaller things can be seen and identified).

Better resolution: Spect technology allows the radiologist to see abnormal findings more accurately.

Multiple : Spect is a modality of nuclear medicine imaging that allows for 3d imaging, therefore better for diagnostic purposes. Uses include scans of the bones, lungs, heart.

Tomography: The nuclear medicine gamma camera moves 360 degrees around patient stopping for information at 64 stops. This allows reconstruction of images in three different planes similar to ct, coronal, sagittal, and transaxial. Some times abnormalities less than centimeter can be detected. Can see abnormality in all three planes. Spect is used for imaging heart, bone, brain, and certain tumors.

SPECT...: In spect, a camera rotates around the patient and allows reconstruction of data so the body can be viewed similar to ct scan. One can scroll through axial, sagittal, or coronal slices to examine tracer distribution in the body. Spatial resolution of spect is worse than planar imaging however contrast resolution is much better, allowing us to distinguish count differences in adjacent tissues.
