- 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.
- Prevalence and Characteristics of Intracranial Aneurysms in Hereditary Hemorrhagic Telangiectasia
In this retrospective study, the authors evaluated the prevalence and characteristics of intracranial aneurysms in patients with hereditary hemorrhagic telangiectasia with brain vascular malformations. In their study cohort of 180 patients with HHT and brain vascular malformations, the authors demonstrated that the prevalence of intracranial aneurysm in hereditary hemorrhagic telangiectasia is comparable with that in the general population without clear association with shunting brain vascular malformations.
- Cervical Osteomyelitis and Diskitis as a Complication of Neopharyngeal Breakdown: A Multisite Case Series Review
This case series of 11 patients status post laryngectomy/pharyngectomy describes the imaging findings of pharyngoesophageal wall breakdown with subsequent cervical spine infection. The authors show that MRI is more sensitive for spine infection in these patients presenting with neck, fever, and serologic evidence of infection.
