ISMRM: 4D MRI reveals heart impairments in patients with COPD
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.

ISMRM: Brain’s waste-clearing system accelerates brain aging after stroke
The brain’s glymphatic system appears to accelerate brain aging in patients after ischemic stroke.
May 10, 2025
Representative T2-FLAIR, CBF maps, choroid plexus segment, free-water maps, ALPS ROI, and 3D T1BRAVO from a stroke patient, and a healthy control. Both individuals are 64 years old in chronological age. The patient displays an evident ischemic lesion in the basal ganglia region on T2-FLAIR imaging. The distinctions between the patient and the healthy control are as follows: CBF (32.22 ml/100g/min vs. 47.70 ml/100g/min), CPVF (1.47 vs. 0.84), VCSFVF (32.50 vs. 11.00), MSFW (0.0455 vs. 0.0313), ALPS (1.04 vs. 1.54), and BPAD (13.21 vs. -1.60).

DL model can aid in diagnosing myocardial ischemia
A deep-learning (DL) model can automatically measure myocardial blood flow on CT scans to help diagnose myocardial ischemia.
April 29, 2025
Representative images from diagnostic analysis of deep learning (DL)-based CT myocardial perfusion imaging (MPI). (A-D) Representative images in a 51-year-old woman with stable angina at presentation. (A) Curved planar reformation and (B) three-dimensional maximum intensity projection images show severe stenosis of the opening left anterior descending artery (arrow). (C) Fractional flow reserve (FFR) determined with invasive coronary angiography helps confirm that there was no hemodynamic significance of the opening left anterior descending artery lesion (arrow). (D) Dynamic CT MPI provided functional information to identify hemodynamically significant stenosis with reference to invasive FFR. Myocardial blood flow (MBF) derived from DL-based CT MPI revealed the absence of decreased myocardial perfusion of the left anterior descending artery territory (the areas outlined in black represent the myocardium subtended by the left anterior descending stenosis, and the color bar is a graphical scale that maps MBF ranges). (E-H) Representative images in a 62-year-old man with exertional chest pain at presentation. (E) Curved planar reformation and (F) three-dimensional maximum intensity projection images show moderate stenosis of the middle left anterior descending artery (arrow). (G) FFR determined at invasive coronary angiography helps confirm that the middle left anterior descending lesion was hemodynamically significant (arrow). (H) Dynamic CT MPI provided functional information to identify hemodynamically significant stenosis with reference to invasive FFR. DL-based CT MPI showed a reduction in MBF within the middle and basal anterior wall of the left anterior descending artery territory (the areas outlined in black represent the myocardium with decreased perfusion, and the color bar is a graphical scale that maps MBF ranges). MBFDL = MBF derived from the DL model.
