Quantification of Myocardial Perfusion Utilizing Computed Tomography

Research output: Contribution to journalReview articlepeer-review


The advancement in computed tomography has permitted the evaluation of coronary arteries using noninvasive means. However, the modality is somewhat limited in arteries with 30 % to 70 % stenosis in the determination of a physiologic impact on perfusion. Improvements in hardware and software now allow for the evaluation of myocardial perfusion with CT. This in conjunction with the CTA has resulted in improvement in sensitivity, specificity, and accuracy in the diagnosis of ischemia. While still a modality in development, it shows promise to be utilized in the low to intermediate risk groups. Even though this is a minimally invasive modality clinicians must be cognizant of the potential overuse resulting in excess radiation dose to patients.
