WebSingle-photon emission computed tomography ( SPECT, or less commonly, SPET) is a nuclear medicine tomographic imaging technique using gamma rays. [1] It is very similar to conventional nuclear medicine planar imaging using a gamma camera (that is, scintigraphy ), [2] but is able to provide true 3D information. WebApr 11, 2024 · PD was first described in 1817 by James Parkinson in his “Essay on the Shaking Palsy”, and the major motor signs identified then still remain the hallmarks of PD: bradykinesia, rigidity, and tremor [3]. Additionally, other common motor symptoms like stiffness, speech difficulty and poor balance and coordination are prevalent whilst …
What is SPECT imaging and how does it work?
WebThere is currently a large variety of technology available, ranging from analog planar NaI-crystal cameras to digital circular geometry solid-state cadmium-zinc-telluride (CZT) designs. These technologies differ in sensitivity, energy resolution, spatial resolution [ 47, 48 ]. WebSep 1, 2024 · There has been an evolutionary leap in SPECT imaging with the advent of camera systems that use solid-state crystals and novel collimator designs configured specifically for cardiac imaging. Solid-state SPECT camera systems have facilitated dramatic reductions in both imaging time and radiation dose while maintaining high … software contable a2
