    Abstract:
    We evaluated the diagnostic value of 123I-metaiodobenzylguanidine (MIBG) and 123I-labeled beta-methyliodophenyl pentadecanoic acid (BMIPP) myocardial SPECTs for evaluating coronary artery disease and left ventricular function, in comparison with the diagnostic value of 201Tl (Tl) SPECT. For forty-nine patients with coronary artery disease, resting MIBG and BMIPP SPECTs were performed to detect coronary artery stenosis, compared with the diagnostic value of exercise Tl. Left ventricular ejection fraction and regional wall motion were compared with the total US (TUS) and regional US (RUS) of resting MIBG and BMIPP SPECTs, and in turn, compared with resting Tl SPECT. The sensitivity of resting BMIPP SPECT for detecting coronary artery stenosis was lower, and the specificity of resting MIBG SPECT was lower than the other two methods. The accuracy of resting MIBG SPECT for evaluating coronary lesions was nearly the same as the accuracy of exercise Tl, but higher than that of BMIPP SPECT. Left ventricular ejection fraction was well correlated with TUS of resting MIBG SPECT (r = 0.80), resting BMIPP SPECT (r = 0.77), and resting Tl SPECT (r = 0.68). Regional wall motion was most correlated with RUS of resting BMIPP SPECT, compared with that of resting Tl and MIBG SPECTs. These data suggest that resting MIBG SPECT is useful for detecting coronary artery disease and that resting BMIPP SPECT is valuable in evaluating regional left ventricular function.
