- 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.
