Yu M, et al. - Using cardiac MRI as a reference standard, researchers studied the diagnostic performance of quantitative parameters generated from dynamic myocardial perfusion CT for evaluation of acute myocardial infarction (AMI) and microvascular obstruction (MVO). They prospectively involved patients who had successful reperfusion treatment within 1 week after AMI between January 1, 2018, and May 31, 2018. At the end of the analysis, 27 patients with 442 vascular segments were involved. According to findings, myocardial blood flow (MBF) is precise and outperforms other quantitative parameters and late iodine enhancement in the diagnosis of AMI and MVO. It is also possible to correctly estimate the AMI and MVO area using MBF.
