- Plaque-Reporting and Data System Related to Cerebrovascular Event Risk with Mild/Moderate Stenosis: A Chinese Atherosclerosis Risk Evaluation II Study
This prospectively acquired multicenter study evaluated carotid Plaque-RADS and its relationship to clinical risk factors and ipsilateral cerebrovascular symptoms. Plaque-RADS=3 was associated with ipsilateral ischemic cerebrovascular events, particularly in patients with mild-to-moderate stenosis, though it was not an independent predictor after adjusting for stenosis or maximum normalized wall index. Higher Plaque-RADS scores on the symptomatic side correlated with advanced age, male sex, and a history of smoking.
- Baseline Gadolinium Enhancement of the Intracranial Aneurysm Wall and 3D Morphologic Change during Long-Term Follow-Up
Intracranial aneurysm wall enhancement at baseline was shown to be associated with an increase in 3D quantified curvedness during long-term follow-up. The study results reinforce previous findings that aneurysm wall enhancement is associated with aneurysm instability, in particular curvedness increase, and suggest that curvedness could be a suitable parameter to capture aneurysm instability.
- Are Deep White Matter Hyperintensities Associated with Amyloid-Related Imaging Abnormalities in Patients with Alzheimer Disease Treated with Lecanemab?
In this retrospective cohort study, it was found that higher baseline burden of deep white matter hyperintensities, as quantified by the Fazekas score, is significantly associated with an increased risk of amyloid-related imaging abnormalities (ARIA) in patients with Alzheimer disease receiving antiamyloid immunotherapy (lecanemab).
- Retrospective Review of MR Findings in Sudden Sensorineural Hearing Loss and Associated Clinical Features
Most cases of sudden sensorineural hearing loss (SSNHL) are idiopathic. In this large cohort study, the incidence of a relevant retrocochlear lesion was 2.7%. Patients with pure tone average values above 49.5 dB or who had tinnitus had higher odds of having a tumor or MR findings of labyrinthitis. All tumors were visible on noncontrast cisternographic images.
- Risk Factors for Epidural Hematoma Expansion and the Need for Surgery
This retrospective study found that the factors associated with larger epidural hematoma size are arterial bleeding sources, mixed attenuation, and the presence of the spot sign. These factors plus midline shift predicted the need for surgery. The epidural hematomas associated with concurrent subarachnoid hemorrhage were more likely to grow with time.
- Reporting the Degree of Certainty of CSF-Venous Fistulas in Patients with Spontaneous Intracranial Hypotension: The Duke CSF-Venous Fistula Confidence Score
The authors of this retrospective study describe a novel structured reporting system based on objective imaging findings that communicates the degree of certainty about the presence of CSF-venous fistula on CT myelography.
