- Comprehensive Review of Inner Ear Anatomy on Photon-Counting CT
Compared to traditional energy-integrating CT detectors, photon-counting CT allows greater spatial and contrast resolution of small channels containing nerves, arteries, and normal anatomy such as the cochlear cleft and cochlear and vestibular aqueducts. This review article updates the existing literature by redefining these structures in greater resolution.
- Involvement Beyond Peripheral Nerves in Pure Neuritic Leprosy: An MR Imaging Study
Many patients with pure neuritic leprosy may have involvement of dorsal root ganglion, brachial plexus (thickening of trunks and cords), lumbar plexus, and spinal cord (intramedullary T2 hyperintensity). Patients may present with ganglionitis, plexitis, or myelitis.
- Vestibular Schwannoma–Related Increased Labyrinthine Postgadolinium 3D-FLAIR Signal Intensity and Association with Hearing Impairment
Increased 3D-FLAIR postgadolinium signal intensity of the ipsilateral labyrinth associated with vestibular schwannoma was shown to be correlated with sensorineural hearing loss. The study found that measured intralabyrinthine signal is associated with greater degrees of sensorineural hearing loss on audiometry.
