TECHNETIUM RADIOPHARMACEUTICALS: APPLICATIONS IN NUCLEAR CARDIOLOGY

摘要

Single photon emission computed tomography (SPECT) with technetium labelled perfusion tracers is a consolidated tool for coronary artery disease diagnosis and for risk stratification. Technetium-99m labelled myocardial perfusion tracers have allowed a significant evolution in myocardial perfusion scintigraphy. Technical improvements in scintigraphic data acquisition, processing and analysis, such as SPECT and gated-SPECT, can be applied in current clinical practice as a consequence of the availability of perfusion tracers with optimal physical characteristics for gamma camera technology. The principal properties of commercially available tracers are analysed.
