Exercise myocardial SPECT using 99mTc-Teboroxime was performed and the regions of ischemic area were compared with 201Tl myocardial SPECT in 8 patients with coronary artery disease. All patients had no evidence of previous myocardial infarction, and underwent bicycle ergometer exercise according to a standardized multistage exercise protocol. At peak exercise, 555 MBq 99mTc-Teboroxime or 75 MBq 201Tl was injected intravenously. After termination of exercise, images were obtained with a gamma camera rotating through a 180 degrees arc from 45 degrees right anterior oblique to 45 degrees left posterior oblique. The concordance of 99mTc-Teboroxime SPECT and 201Tl SPECT was 63% in ischemic region and 83% in normal region. Furthermore, one patient underwent dipyridamole infusion and 99mTc-Teboroxime SPECT was carried out. The images obtained by dipyridamole 99mTc-Teboroxime SPECT were equivalent to the images of exercise 201Tl SPECT. 99mTc-Teboroxime SPECT seems useful for the detection of the coronary artery disease. It was suggested that evaluation of the myocardial viability in acute phase of myocardial infarction can be possible by using 99mTc-Teboroxime SPECT.

D011237 Predictive Value of Tests In screening and diagnostic tests, the probability that a person with a positive test is a true positive (i.e., has the disease), is referred to as the predictive value of a positive test; whereas, the predictive value of a negative test is the probability that the person with a negative test does not have the disease. Predictive value is related to the sensitivity and specificity of the test.
