title: [Comparison between myocardial perfusion scintigraphy with thallium-201 and technetium-99m-Sestamibi (methoxy isobutyl isonitrile) for the detection of coronary atherosclerotic disease].
abstract: 99mTc-SESTAMIBI is a new myocardial perfusion agent used in the detection of atherosclerotic coronary artery disease. In the present study, myocardial scintiscanning (on treadmill) with 99mTc-SESTAMIBI and 201-Thallium were compared, and both were compared with coronary angiography. Some 130 consecutive patients were evaluated within an interval of a few weeks with scintiscans of both 99mTc-SESTAMIBI and 201-Thallium: 82 of them were also examined by coronary angiography. Segmental analysis of the two series of scans revealed some correlation in 89.2% of the segments, while correlation of the final diagnosis showed agreement in 92% of cases. Compared to coronary angiography, sensitivity in the detection of CAD was found to be 75.8% for 201-Thallium and 72.5% for 99mTc-SESTAMIBI. The authors conclude that 99mTc-SESTAMIBI is a promising myocardial perfusion agent which displays an excellent correlation with 201-Thallium.
