- 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.
- Comparison of a Whole-Brain Contrast-Enhanced 3D TSE T1WI versus Orbits Contrast-Enhanced 2D Coronal T1WI at 3T MRI for the Detection of Optic Nerve Enhancement in Patients with Acute Loss of Visual Acuity
This retrospective, single-center study of 1023 patients presenting with acute loss of vision compared orbits contrast-enhanced 2D coronal T1WI with a whole-brain contrast-enhanced 3D TSE T1WI at 3T for the detection of optic nerve enhancement. The latter (WBCE-3D T1WI) demonstrated higher sensitivity and specificity in diagnosing optic neuritis, particularly in cases involving the canalicular segments.
