Axial (A) and Coronal (B) CTPA show multiple partial intraluminal filling defects along the course of the right middle lobar segmental branches (medial segment) (yellow arrow) and lower lobar and postero-medial segmental branches (green arrow). Note the low-signal filling defects on the axial and coronal 0.55T MRI sequence.

Associations between insulin resistance and MWF. (A) Distribution of insulin resistance, stratified by sex. (B) Regression analysis of whole-brain MWF vs. log (HOMA-IR), adjusted for age and age². Shaded regions indicate 95% confidence intervals. (C) Regression analysis of whole-brain MWF vs. log (HOMA-IR), adjusted for age, age², sex, and log (HOMA-IR) sex.

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).
ISMRM: Brain’s waste-clearing system accelerates brain aging after stroke
May 10, 2025
Researchers at ISMRM highlighted the success of a trimodal MR-PET-FUS system built around a low-field MRI scanner. MR (top) and PET (bottom) images were acquired simultaneously before and after FUS heating.

Protocol time and recall bounds as a function of AI specificity and sensitivity. On the top, the bounds are shown as a function of the specificity of the AI algorithm, for a fixed value of the sensitivity of that same AI model. On the bottom, the bounds are shown as a function of the sensitivity, for a fixed specificity. Graphics and caption courtesy of the ISMRM.
