Due to its widespread use, there are more trained technologists available too. It is very similar to conventional nuclear medicine planar imaging using a gamma camera (that is, scintigraphy), but is able to provide true 3d information. The main difference between spect and pet scans is the type of radiotracers used. The presence of an intermediate positronium in pet.

It’s also much more affordable, with the average camera costing between $400,000 and $600,000. This is a common feature of gamma cameras that are to be used for spect because it allows two different projection images to be acquired simultaneously. Spect (single.

Because the detection techniques of gamma cameras and spect are based on the same concept, the same radioisotopes can be used for both techniques. While spect scans measure gamma rays, the decay of the radiotracers used with pet scans produce small particles called positrons. Spect (single photon emission computed tomography) imaging, as used in nuclear cardiac stress testing, is performed.

Broadly, components of a gamma camera and spect imaging device consist of a detector (collimator, detector, photomultiplier tube, and preamplifier), processing (position logic circuit, amplifier, correction circuit, pulse height analyzer), and display (monitor) units (cherry et al., 2003). This advantage can be put to use in one of three ways. Quality control of gamma camera with spect system is highly.
