- β-Trace Protein as a Potential Biomarker for CSF-Venous Fistulas
This prospective study of patients with CVF compared the levels of β-trace protein (BTP) in paraspinal veins near the CVF with those in the peripheral blood and in the peripheral blood of controls. Venous blood at the site of the CVF was shown to have higher BTP values compared with peripheral blood in most patients with CVF. It was also found that patients with CVF had a lower peripheral blood BTP level compared with controls.
- Safety and Technical Performance of Bilateral Decubitus CT Myelography Using Standard versus Increased Intrathecal Iodinated Contrast Volume
In this retrospective study, the authors assessed the tolerability and technical performance of increased intrathecal doses (20 mL) of myelographic contrast compared with standard doses (10 mL). They found that the increased volume of intrathecal contrast was well-tolerated and improved the technical performance of LDCTM.
- Dynamic Expansion and Contraction of Multiple Sclerosis T2-Weighted Hyperintense Lesions Are Present below the Threshold of Visual Perception
Recognition of longitudinal imaging changes of MS lesions has substantial implications for clinical management, but changes may remain below the resolution of human perception. In this study, the authors demonstrated that T2-weighted hyperintense lesions undergo dynamic change on MRI, with predominantly enlarging or contracting characteristics, more frequently seen in untreated individuals.
- Assessment of Attenuation in Pericarotid Fat among Patients with Carotid Plaque and Spontaneous Carotid Dissection
This cross-sectional retrospective study assessed the PFD in patients with spontaneous internal carotid artery dissection or carotid atherosclerotic plaque, with and without IPH. The results showed that the average PFDs in patients with SICAD and carotid atherosclerosis plaque with IPH were similar and higher than those in patients with carotid plaque without IPH, suggesting a shared pathologic inflammatory mechanism in these 2 conditions.
