Head-to-head comparison of non-invasive coronary artery imaging

For patients presenting for the first time with suspected coronary artery disease (CAD), clinicians have had a number of non-invasive diagnostic tests to choose from, but little evidence for which is best. Now, findings from the PACIFIC trial may offer some guidance.

The first head-to-head comparison of the most commonly used non-invasive techniques to evaluate myocardial perfusion or coronary artery stenosis severity found that positron emission tomography (PET) had more diagnostic accuracy than either single photon emission computed tomography (SPECT) or coronary computed tomography angiography (CCTA), researchers reported.
