Cost-effectiveness of Electron-Beam Computed Tomography in the Diagnosis of Coronary Artery Disease

Arch Intern Med. 2001;161(21):2624. doi:

I read with interest the article on electron-beam computed tomography (EBCT) in the diagnosis of coronary artery disease (CAD) by Nallamothu et al.1 I was particularly amused by the authors' concluding remark that "EBCT appears to be reasonably accurate at detecting obstructive CAD in patients undergoing coronary angiography, with sensitivity and specificity comparable to those reported for traditional exercise stress testing"1 (italics mine). But the authors did not mention the relative costs of EBCT and traditional exercise stress testing; EBCT costs much more than the traditional exercise stress testing.
