Utility and limitations of 18F-fluciclovine PET for biopsy targeting in a nonenhancing diffuse glioma with a gliomatosis cerebri–like growth pattern: illustrative case

Contrast-enhanced MRI reflects blood-brain barrier (BBB) disruption rather than tumor biological activity, whereas 18 F-fluciclovine ( 18 F-FACBC) PET reflects amino acid metabolism independent of BBB integrity. The authors compared regional 18 F-FACBC uptake with histopathological and molecular findings in...

Clinical characteristics of postoperative anterior arch fracture of the atlas following C1 laminectomy: 14-year experience of a single neurosurgical center

ABSTRACT Objective: Postoperative anterior arch fracture of the atlas (PAFA) is a rare but increasingly recognized complication of C1 laminectomy. However, the pathophysiology remains poorly understood. We retrospectively investigated the incidence of PAFA and associated risk factors. Methods: We retrospectively review...

Glioma Segmentation on Multicenter 2D-Based Magnetic Resonance Imaging Using Low-Rank Adaptation Tuning of a Foundation Model: An External Test Evaluation.

Evaluating SAM, MedSAM, and their LoRA-tuned variants (SAM-LoRA and MedSAM-LoRA) using brain magnetic resonance images of gliomas from five centers in Japan and to compare their performance suggested potential utility.
