Abstract
En 中文
Photon-counting detector CT is an emerging technology that has the promise to dramatically transform clinical practice. It largely overcomes the limitations of traditional CT, offering ultra-high spatial resolution, suppression of metallic artifact, and reduced radiation dose. We report the case of a 44-year-old patient presenting with gaze-evoked vision loss and history of a retained orbital foreign body. Localization of the foreign body on conventional CT was limited by metallic artifacts, and magnetic resonance imaging was contraindicated. Photon-counting detector CT effectively localized the foreign body and guided management. The potential applications of this newer technology in neuro-ophthalmology are still being explored.
