ISMRM: Adding dobutamine stress imaging to CMR feasible
By Amerigo Allegretto
Adding dobutamine stress imaging during clinical cardiovascular MR exams is feasible for separating athletic hearts from hearts with early DCM.
May 14, 2025
Research presented at ISMRM 2025 found that adding dobutamine stress imaging to CMR can separate athletic hearts from hearts with early DCM. The stress CMR findings correlated well with CPET results, highlighting the feasability of adding dobutamine stress imaging to CMR exams.
ISMRM: AI spots ischemic heart disease on low GBCA dose images
By Erik L. Ridley
An AI-based framework was highly accurate for detecting myocardial ischemia, even on images acquired with 90% less gadolinium.

Representative stress perfusion CMR case with 80% contrast dose reduction. Pixel-wise MBF maps and AHA 16-segment bull's eye plots are shown for full-dose and reduced-dose acquisitions. When analyzed using the proposed MST deep learning method, the reduced-dose data closely matches the full-dose data across basal, mid, and apical slices. In contrast, Fermi-deconvolution shows good agreement in apical and mid slices but overestimates MBF in some basal segments, indicating reduced accuracy under low-dose conditions.

ISMRM: 4D MRI reveals heart impairments in patients with COPD
By Will Morton
Research presented at ISMRM 2025 highlighted how 4D flow MRI reveals cardiopulmonary hemodynamic interaction in patients with COPD.
May 12, 2025
Examples of hemodynamic parameter maps superimposed on their corresponding anatomic data for two participants. Participant A represents an example of good flow with lower right ventricle stasis, increased right atrium kinetic energy, and increased mean velocity when compared to the sample’s average calculations. Opposite findings are highlighted by the visualizations of participant B representing an example of poor flow.
