To the Editor: In their study of the accuracy of 16-row multidetector computed tomography (MDCT) for assessment of coronary artery stenosis, Dr Garcia and colleagues1 conclude that MDCT angiography may be useful to exclude coronary artery disease in selected patients in whom a false-positive stress test result is suspected. We have a number of questions about this conclusion and the study.
First, to establish such a role, there must be an assessment of the correlation between clinical pretest probability (55% [132/238] at high risk and 45% [106/238] at intermediate risk), stress test results (abnormal in 117 [74%] of the 158 patients in whom it had been performed), and angiographic outcomes as evaluated by MDCT and quantitative coronary angiography. It would be helpful to know if such an analysis was performed.
Second, the study demonstrated poor accuracy of 16-row MDCT due to a high false-positive rate and a significant false-negative rate. . . . [Full Text of this Article]
