TO THE EDITOR:
We read with great interest the meta-analysis by Schuetz and colleagues (1), which aims to compare the diagnostic accuracy of coronary angiography with computed tomography (CT) and magnetic resonance imaging (MRI) against invasive radiographic coronary angiography. The main result was that CT coronary angiography was more accurate than MRI coronary angiography.
We completely agree that CT is the more accurate of the 2 tests for noninvasive coronary angiography. This is generally accepted within the field, which is why, as noted by the authors, relatively few articles have been published in recent years on MRI coronary angiography. However, whereas the study title correctly refers to “noninvasive coronary angiography” by CT and MRI, the remainder of the text and its conclusions refer less specifically only to “CT” and “MRI.” This generalization opens the study to potential misinterpretation.
