- 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.
- T1-Weighted, Dynamic Contrast-Enhanced MR Perfusion Imaging Can Differentiate between Treatment Success and Failure in Spine Metastases Undergoing Radiation Therapy
Routine MRI techniques are rather limited in assessing treatment response versus disease progression following radiation therapy as lesion size often fluctuates after both successful and unsuccessful treatment. In this study, dynamic contrast-enhanced MRI perfusion parameters were used to predict treatment success or failure regarding spinal osseous metastases and to show the concordance with lesion-size measurements in the determination of treatment success or failure. The authors found there were significant differences in the change in plasma volume following radiation treatment between their clinical response and persistent disease groups. Additionally, they demonstrated that plasma volume had a higher specificity than size measurements.
- Factors Predictive of Treatment Success in CT-Guided Fibrin Occlusion of CSF-Venous Fistulas: A Multicenter Retrospective Cross-Sectional Study
Multi-institutional retrospective evaluation of patients with CSF-to-venous fistulas treated with CT-guided fibrin glue treatment showed that treatment success may be in part driven by whether the spread of fibrin injectate matches the target drainage pathway of the CVF.
