摘要

摘要：光子计数检测器CT是一项新兴技术，有望极大地改变临床实践。它在很大程度上克服了传统CT的局限性，具有超高空间分辨率、抑制金属伪影、降低辐射剂量等优点。我们报告一个44岁的病人的情况下，提出了目光引起的视力丧失和历史保留的眼眶异物。传统CT对异物的定位受到金属伪影的限制，磁共振成像是禁忌。光子计数检测器CT能有效定位异物，指导处理。这项新技术在神经眼科的潜在应用仍在探索中。

Photon-Counting Detector CT: Promise of a New Era.

Abstract: 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.
