- Change in Emergency Department Length of Stay following Routine Adoption of Dual-Energy CT to Differentiate Intracranial Hemorrhage from Calcification
This retrospective study compared ED LOS over a 1-year period before and after implementing automated DECT processing in the evaluation of indeterminate intracranial hyperdensities. The authors showed that with intracranial indeterminate hyperdensities, there was a larger statistically significant difference in pre-DECT versus post-DECT ED LOS. The pre-DECT ED LOS correlated with increased frequency of neurosurgical consultation and repeat head CT.
- Development and Evaluation of Automated Artificial Intelligence–Based Brain Tumor Response Assessment in Patients with Glioblastoma
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.
