- Skull Base CSF Leaks: Potential Underlying Pathophysiology and Evaluation of Brain MR Imaging Findings Associated with Spontaneous Intracranial Hypotension
The purpose of this study was to use a validated brain MRI scoring system (Bern score) to evaluate patients with confirmed skull base CSF leaks for findings associated with SIH. The authors found that patients with skull base CSF leaks did not have brain MRI findings that are associated with SIH and likely have distinct pathophysiology from spinal CSF leaks.
- Retrolabyrinthine Bone Thickness as a Radiologic Marker for the Hypoplastic Endotype in Menière Disease
There are 2 major endotypes of Menière disease: one with a hypoplastic, underdeveloped endolymphatic sac and one with a normally developed sac that degenerates over time. This study explored the link between angular trajectory of the vestibular aqueduct and the thickness of the retrolabyrinthine bone to provide differentiation between MD endotypes using CT and MRI. The average retrolabyrinthine bone thickness was statistically significantly different between endotypes with retrolabyrinthine bone thickness >=1.2 mm, effectively ruling out hypoplastic Menière disease.
- Photon-Counting CT in the Head and Neck: Current Applications and Future Prospects
This article reviews the current clinical application of PCD-CT in head and neck imaging, specifically the temporal bones, facial bones, and paranasal sinuses. PCD-CT offers improved spatial resolution, better iodine contrast-to-noise ratio, reduced artifact, and lower radiation dose.
