Metamaterial Antennas Enhance MRI of the Eye and Occipital Brain

Advanced Materials, EarlyView.
A radiofrequency antenna platform comprising planar and bend configurations is developed, incorporating structurally integrated epsilon‐negative metamaterial unit cells to enhance MRI. These antennas enable high‐resolution in vivo human MRI of the eye, orbit, and occipital brain. Comprehensive validation, including simulations, phantom experiments, SAR,

Microvascular tissue transfer in reconstruction of anterior skull base defects secondary to sinonasal malignancies: a case series and proposed reconstructive framework

Egyptian Journal of Neurosurgery
Sinonasal malignancies such as lymphoepithelial carcinoma (LEC) and esthesioneuroblastoma (ENB) are rare but aggressive neoplasms that frequently necessitate extensive resection of anterior skull base structures, creating complex defects.
