- Radiogenomics Provides Insights into Gliomas Demonstrating Single-Arm 1p or 19q Deletion
The results of this study show that imaging and survival data of tumors with single-arm 1p or 19q deletion are equivalent to IDH-mutant astrocytomas rather than oligodendrogliomas. Not only does this support our understanding of the neurobiologic underpinnings, but it also provides reassurance in the management of these tumors with 1p- or 19q-unideletion as astrocytomas, in keeping with the WHO classification.
- Specificity of Quantitative Functional Brain Mapping with Arterial Spin-Labeling for Preoperative Assessment
This study assessed the performance of ASL compared with BOLD imaging for localization specificity of functional cortex during motor and somatosensory tasks in a cohort of healthy subjects, using TMS hand somatotopy depicted as the ground truth.
- Prevalence of Cochlear-Facial and Other Non-Superior Semicircular Canal Third Window Dehiscence on High-Resolution Temporal Bone CT
This study of 500 patients found the prevalence of non-SSCD on high-resolution CT in asymptomatic individuals to be 1.6% for CFD and 8.0% for JVD as compared with the rate in patients with audiologic or vestibular symptoms (2.9% for CFD and 7.8% for JVD). There was no statistically significant difference in the rates of radiologic findings between patients with reported symptoms suggestive of a possible third window syndrome and those without auditory or vestibular symptoms.
- MR Imaging Appearance of Ruptured Rathke Cleft Cyst and Associated Bone Marrow Enhancement
This clinical case series of 7 patients illustrates the imaging finding of enhancing basisphenoid bone marrow below the sella in cases of ruptured RCC. The mucin leaking out of the ruptured RCC can trigger a cascade of surrounding inflammation, which manifests as abnormal bone marrow enhancement.
