Myocardial perfusion CT closes in on cardiac fMRI

June 3, 2008 Diagnostic Imaging. Myocardial perfusion CT closes in on cardiac fMRI MRI still generates better contrast and less noise than perfusion CT on delayed enhancement images -------------------------------------------------------------------------------- With piles of accumulated evidence demonstrating the ability of multislice CT to diagnose coronary artery disease, researchers are expanding clinical application of the modality to the measurement of myocardial viability following infarction. Clinicians are increasingly calling for first-pass and delayed-enhancement myocardial MRI to assess post-MI myocardial damage and gauge the potential value of coronary revascularization. Now, a preliminary study shows that first-pass and delayed-enhancement CT can also play those roles.
