The goal of this study was to compare AI-based volumetric GBM MRI response assessment with standardized radiologist response assessments. The AI-based volumetric response assessment yielded overall moderate performance for recapitulating most human response assessment categories (BT-RADS 1, 2, and 4) but demonstrated the lowest performance for predicting BT-RADS 3, which is likely related to the high variability of this assessment. In comparison to radiologist assessment, the AI-based volumetric GBM MRI response assessment showed comparable performance for overall survival.

The purpose of this retrospective cohort study was to assess the quantity and distribution pattern of WMH in patients with suspected SIH who underwent subsequent dynamic CTM. Patients with CVF had significantly higher Bern scores and significantly fewer WMH than those without CVF. Also, the migraine-type pattern of WMH was present at a nearly 4-fold greater frequency in the CVF- group versus the CVF+ group. Additionally, the symptom data demonstrated distinct clinical phenotypes between patients with CVF (eg, higher occurrence of a pressure-type or throbbing headache, symptoms worsening with the Valsalva maneuver) and those without CVF (eg, neck pain, fatigue, photophobia, and phonophobia).

This retrospective single-center cohort study investigated the discrepancy of 2 widely used postprocessing tools (Syngo.via and RapidAI) for CTP in patients with medium/distal vessel occlusion (MDVO) stroke. The 2 postprocessing tools were discordant on the volume and the location of perfusion deficit in isolated MDVO as well as the volume of potentially salvageable penumbra. As such, this questions whether infarct core size or penumbra volume should routinely be used to identify candidates for MDVO thrombectomy.

This meta-analysis evaluated randomized clinical trial results to provide more definitive guidance on the role of EVT for patients with stroke with large infarcts based on perfusion metrics. The results showed that the effectiveness of thrombectomy is uncertain regarding the safety and efficacy of thrombectomy for patients with limited areas of at-risk tissue. EVT may be beneficial for those with intermediate perfusion mismatch (ratio of 1.2-1.8 or volume of 10-15 mL) but not for those with low perfusion mismatch (ratio <1.2 or volume <10 mL).
