Open AccessUncertainty-aware deep-learning model for prediction of supratentorial hematoma expansion from admission non-contrast head computed tomography scan
Hematoma expansion (HE) is a modifiable risk factor and a potential treatment target in patients with intracerebral hemorrhage (ICH). We aimed to train and validate deep-learning models for high-confidence pre...

Monitoring the effects of BCNU chemotherapy Wafers (Gliadel®) in glioblastoma multiforme with proton magnetic resonance spectroscopic imaging at 3.0 Tesla
Carmustine wafers (Gliadel® Wafer) are implanted at resection in some patients with high-grade gliomas. Studies suggest that proton magnetic resonance spectroscopic imaging (1H MRSI) demonstrates early changes pr...
