SPECT & Gamma Camera
SPECT (Single-Photon Emission Computed Tomography) is a diagnostic imaging technique used in nuclear medicine which studies PHYSIOLOGICAL (FUNCTIONAL) processes in the body. Gamma cameras are used to construct an image of the distribution of radiopharmaceuticals spread out in the body of a patient. Principle [edit | edit source]
SPECT – Wikipédia
A SPECT vagy SPET (Single photon emission computed tomography: egyfoton-kibocsátásos, számítógépes metszeti képalkotás) gamma-sugarakat használó non-invazív, vagyis beavatkozást nem igényelő orvosi képalkotó eljárás. A funkcionális képalkotó eljárások körébe tartozik, vagyis nem az anatómiai viszonyokat, hanem a ...
