- Newly Recognized Genetic Tumor Syndromes of the CNS in the 5th WHO Classification: Imaging Overview with Genetic Updates
In this review of the new 5th edition of the WHO classification, the authors focus on imaging and genetic characteristics of 8 new syndromes: Elongator protein complex-medulloblastoma syndrome, BRCA1-associated protein 1 tumor-predisposition syndrome, DICER1 syndrome, familial paraganglioma syndrome, melanoma-astrocytoma syndrome, Carney complex, Fanconi anemia, and familial retinoblastoma.
- Clinical and Imaging Findings in Children with Myelin Oligodendrocyte Glycoprotein Antibody Associated Disease (MOGAD): From Presentation to Relapse
This study characterizes the CNS imaging manifestations of pediatric MOGAD. The authors also identify the clinical and imaging variables associated with relapse. There is an age-dependent imaging phenotype at presentation and first relapse, and older age at presentation is associated with shorter time to relapse.
- Frequency of Coexistent Spinal Segment Variants: Retrospective Analysis in Asymptomatic Young Adults
Spinal segment variants are highly prevalent and can potentially lead to incorrect spinal enumeration. The objective of this study was to assess the prevalence of spinal segment variants and to study the potential association among these variants in an asymptomatic population. The results showed that the spinal segment variants are highly prevalent, ranging from 4.2% (cervical rib) to 26.4% (LSTV), and that these variants are associated with each other. The authors recommend further imaging for spine enumeration before interventions or operations when a spinal segment variant is identified.
- CTA and CTP for Detecting Distal Medium Vessel Occlusions: A Systematic Review and Meta-analysis
This systematic review and meta-analysis aimed to compare the diagnostic test accuracy for CTA and CTP in the detection of distal medium vessel occlusion. The study found consistent evidence for a higher sensitivity in detecting distal medium vessel occlusion, particularly in arteries beyond the M2 segment of MCA, with multiphase CTA or CTP compared with single-phase CTA.
- Temporal Characteristics of CSF-Venous Fistulas on Dynamic Decubitus CT Myelography: A Retrospective Multi-Institution Cohort Study
This retrospective multi-institution cohort study analyzed the temporal features of CSF-venous fistula (CVF) visualization on dynamic decubitus CT myelography (dCTM) in 48 patients. The results showed that most CVFs were visible on first or subsequent phases of dCTM, but approximately 1 in 8 were only visible on either the early or delayed phase. The authors conclude that acquiring greater than 1 phase of imaging increases the sensitivity of dCTM by increasing its temporal resolution.
