Overview

Randomized trial evaluates MRI for predicting lesion patterns in glioblastoma using non-thermal ultrasound, suggesting enhanced treatment monitoring potential.

Key Points

The aim is to quantitatively assess MRI's effectiveness in evaluating lesions post non-thermal focused ultrasound ablation for glioblastoma.
Using seven male Fischer rats, including five healthy and two with glioma tumors, MRI assessments were performed post non-thermal focused ultrasound.
Hemorrhage-related hypointensities in T2*-weighted MRI were characterized across various echo times, with ground-truth derived from histology using H&E staining.
A learning-based framework was introduced to improve lesion prediction accuracy by fusing multi-parametric MRI data.
The optimal echo time for MRI assessment was TE = 26 ms, showing high spatial agreement with histology (soft Dice coefficient).
The multi-parametric fusion achieved 45% higher accuracy (soft Dice 0.51) in predicting hemorrhage patterns compared to T2* imaging alone (soft Dice 0.35 at TE=26 ms).
Analysis demonstrated robustness in the treatment region, indicating the potential for improved monitoring of non-thermal ultrasound therapies.
