Imaging Performance of Stress/Delayed Tl-201 ECG-Gated SPECT (GSPECT) in an Asian Population: A Comparative Study of Rest/Stress Tc-99m Sestamibi (MIBI) GSPECT

摘要

Background: We investigated the differences of perfusion and functional parameters obtained from Tl-201 and Tc-99m sestamibi (MIBI) myocardial perfusion electrocardiogram (ECG)-gated single photon emission computed tomography (GSPECT) in an Asian population. Methods: Two matched groups of 60 low-likelihood coronary artery disease (CAD) patients (LL group) (male = 56, female = 64; age = 46.0 ± 8.8 years; body mass index (BMI) = 25.9 ± 3.2 kg/m2) and a group of 60 known CAD patients (CAD group) (male = 47, female = 13; age = 62.2 ± 11.7 years; BMI = 26.1 ± 3.3 kg/m2) were recruited. The LL groups underwent either Tl-201 or MIBI myocardial perfusion GSPECT while the CAD group received both examinations within 10 days.
