A case of an intraorbital wooden foreign body mimicking air on standard CT window setting and on MR is presented. Its higher attenuation with higher CT window setting as well as its elongated and well-delineated shape on both CT and MR helped to distinguish it from air.
本文报告一例眼眶内木质异物病例,该异物在标准CT窗宽设置及磁共振成像(MR)上表现类似空气。在较高CT窗宽设置下其衰减值较高,以及在CT和MR上均呈细长且边界清晰的形态,有助于将其与空气区分开来。
