- Ecchordosis Physaliphora: Does It Even Exist?
Notochordal lesions span a spectrum of disease ranging from benign notochordal remnant (ecchordosis physaliphora) to low-grade to aggressively malignant. Benign notochordal remnant cannot be reliably distinguished from low-grade chordoma as they may have overlapping imaging features. Repeat imaging, beginning at 6-month intervals, is a more clinically relevant method for evaluating the malignant potential of these lesions.
- Performance of Automated ASPECTS Software and Value as a Computer-Aided Detection Tool
This retrospective study compared the agreement of automated ASPECTS and raters with a different experience level in scoring patients with acute ischemic stroke with large-vessel occlusion undergoing thrombectomy. The agreement of all raters individually versus the criterion standard and interrater agreement improved with software assistance.
- T2-FLAIR Mismatch Sign in Pediatric Low-Grade Glioma
The T2-FLAIR mismatch sign was not observed in pediatric low-grade gliomas with the common molecular alterations BRAF p.V600E–mutated and KIAA1549-BRAF fused, while it was encountered in low-grade gliomas with rare pediatric molecular alterations.
