Can MRI Predict Perforator Stroke Progression?

Investigators evaluate multisequence imaging for its ability to identify patients at risk for neurologic progression.

1

A radiomics model using multiparameter MRI can predict neurologic deterioration in subacute ischemic perforator artery infarction.
2

The model achieved an area under the curve of 0.844 in the training cohort and 0.824 in the validation cohort.
3

The study included 188 patients with single-lesion subacute ischemic perforator artery cerebral infarction.
4

Combined radiomic features from multiple MRI sequences outperformed single-sequence models in predicting progression.
5

The study faced limitations including modest sample size, lack of external validation, and retrospective design.
