Article Synopsis
- Myocardial blood flow (MBF) and myocardial perfusion reserve (MPR) from stress cardiovascular magnetic resonance (CMR) effectively identify obstructive coronary artery disease (obCAD) and may outperform conventional qualitative assessments by experienced physicians.
- In a study of 127 individuals, lower global sMBF and MPR were observed in patients with obCAD compared to those without, indicating a significant correlation with disease presence.
- The statistical analysis showed that the area under the curve (AUC) for quantitative sMBF and MPR was at 0.90 and 0.86, respectively, which is higher than the AUCs ranging from 0.69 to 0.88 found in traditional qualitative assessments
Comprehensive review of artifacts in cardiac MRI and their mitigation.

Cardiac magnetic resonance imaging (CMR) is an important clinical tool that obtains high-quality images for assessment of cardiac morphology, function, and tissue characteristics. However, the technique may be prone to artifacts that may limit the diagnostic interpretation of images. This article reviews common artifacts which may appear in CMR exams by describing their appearance, the challenges they mitigate true pathology, and offering possible solutions to reduce their impact.

Background: Quantitative stress cardiac magnetic resonance (CMR) can be performed using the dual-sequence (DS) technique or dual-bolus (DB) method. It is unknown if DS and DB produce similar results for myocardial blood flow (MBF) and myocardial perfusion reserve (MPR). The study objective is to investigate if there are any differences between DB- and DS-derived MBF and MPR.

- The study aimed to validate cardiac magnetic resonance (CMR) for assessing left ventricular (LV) diastolic dysfunction (DD) by comparing it with transthoracic echocardiography (TTE) in patients with suspected cardiomyopathy and healthy volunteers.
- The results showed a high concordance of 78.1% between CMR and TTE classifications of LV diastolic function, indicating that both methods are largely in agreement with each other.
- CMR could be potentially integrated into routine clinical practice for evaluating LV diastolic function, as it correlates well with established TTE parameters.
This study clinically implemented a ready-to-use quantitative perfusion (QP) cardiovascular magnetic resonance (QP CMR) workflow, encompassing a simplified dual-bolus gadolinium-based contrast agent (GBCA) administration scheme and fully automated QP image post-processing. Twenty-five patients with suspected obstructive coronary artery disease (CAD) underwent both adenosine stress perfusion CMR and an invasive coronary angiography or coronary computed tomography angiography. The dual-bolus protocol consisted of a pre-bolus (0.
