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.
ISMRM: Synthetic MRI feasible for breast cancer screening
By Kate Madden Yee
Synthetically generated "postcontrast" screening breast MR images show promise as an alternative to contrast MRI exams in women with contrast-related contraindications.

ISMRM: fMRI identifies key brain regions in superagers
By Will Morton
Functional MRI (fMRI) has shed new light on brain areas that differentiate superagers from cognitively average older adults.
May 11, 2025
A lollipop plots showing the most important nodes by RF-MLA selected by Mean decrease in Gini for a 7 tesla fMRI dataset, with longer sticks meaning greater importance. Each group of networks’ nodes has its own color matching the same network’s color in the brain map. Nodes' names preceded by a red asterisk are repeated among different networks, matching the red nodes in the brain map, which appear in multiple networks.

ISMRM: Novel MRI technique identifies changes in brain entropy
By Kate Madden Yee
A novel MRI technique called quantitative magnetization transfer (qMT) identifies changes in brain entropy due to normal aging.
May 11, 2025
Regions of interest depicted in colors: cerebrospinal fluid (blue), cortical gray matter (dark green), and white matter (yellow). Scatter plots present significant correlations between (b) [semi-solid spin pool size, or ms0m0s] entropy and age in cerebrospinal fluid and cortical gray matter, and (c) [longitudinal relaxation rates, or Rf1R1f] entropy and age in cortical gray matter and white matter (p < 0.05).

ISMRM: Exercise may reduce structural brain changes
By Liz Carey
Researchers examine the relationship between exercise intensity, brain volume changes, and depression.
May 11, 2025
Boxplot showing significantly larger brain volumes in individuals engaging in vigorous daily exercise compared to those with sedentary or moderate activity levels. The exercise intensity-brain volume pattern is similar across both depressed and nondepressed individuals.
ISMRM: Contrast-free MR angiography comparable to CT for PE detection
By Liz Carey
University of Michigan researchers investigate detectability of pulmonary embolism by noncontrast MR angiography at 0.55 tesla.
May 10, 2025
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.
ISMRM: Insulin resistance in women associated with less myelin, changes in brain
By Maryam Payne
ISMRM research indicates that higher insulin resistance is associated with less myelin in women.
May 10, 2025
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.
