- Does CISS MRI Reliably Depict the Endolymphatic Duct in Children with and without Vestibular Aqueduct Enlargement?
In this retrospective review of temporal bone high-resolution CT and CISS MR imaging of 98 hearing-impaired children, the authors found that the CISS MR imaging technique commonly used for inner ear evaluation performs poorly overall at resolving the endolymphatic duct and underdiagnoses enlarged vestibular aqueduct. If the endolymphatic duct is easily seen on CISS imaging, there is a .99% probability that the vestibular aqueduct is enlarged.
- Hemorrhage Volume Drives Early Brain Injury and Outcome in Poor-Grade Aneurysmal SAH
Early brain injury (radiologically defined by global cerebral edema) is a major determinant of clinical outcome in poor-grade aneurysmal SAH. In this retrospective study of 400 patients with poor-grade aneurysmal SAH, it was shown that intracerebral hemorrhage volume independently predicted global cerebral edema and long-term outcome, intraventricular hemorrhage volume predicted mortality and long-term outcome, and SAH volume predicted long-term clinical outcome.
- Expanding the Imaging Spectrum of Polymorphous Low-Grade Neuroepithelial Tumor of the Young in Children
The imaging spectrum of neuroimaging features in a series of pediatric patients with a histologically and molecularly proven polymorphous low-grade neuroepithelial tumor of the young is described, including the transmantle-like sign and adjacent cortical dysplasia.
- Efficacy of MR Neurography of Peripheral Trigeminal Nerves: Correlation of Sunderland Grade versus Neurosensory Testing
The current diagnostic reference standard for peripheral trigeminal nerve injuries is neurosensory testing in combination with clinical findings to determine treatment. MRN provides an alternative method for the diagnosis and staging of patients with PTN because of its ability to delineate anatomy and the exact location of injury. This study correlates injury grading based on NST and MRN, demonstrating similar rates of agreement with surgical findings in lower-grade injuries but higher rates of agreement between MRN and surgical findings than NST in higher-grade injuries.
