Does SPECT imaging with (99m)Tc-HL91 and (99m)Tc-MIBI accurately detect ischaemic viable myocardium in patients with coronary artery disease?
SPECT imaging with (99m)Tc-HL91 and (99m)Tc-MIBI demonstrates high sensitivity and specificity for detecting ischaemic viable myocardium in patients with coronary artery disease.
Liu et al. (2011) conducted an observational in coronary artery disease (n=41). (99m)Tc-HL91 and (99m)Tc-MIBI SPECT imaging vs. Resting (99m)Tc-MIBI myocardial perfusion imaging after revascularization was evaluated on Detection of ischaemic viable myocardium. (99m)Tc-HL91 and (99m)Tc-MIBI SPECT imaging detected ischaemic viable myocardium with 90.9% sensitivity, 100% specificity, and 92.3% accuracy.
