Radiologic Differentiation of Intraocular Glass

摘要: OBJECTIVE. The accurate detection of intraocular foreign bodies is critically important in treating ocular trauma. purpose this study was to evaluate the efficacy CT, MR imaging, and sonography detecting seven types glass varying size placed three locations globe, examine effect hemorrhage.MATERIALS AND METHODS. Glass pieces were cut into 1.5-, 1.0-, 0.5-mm implanted on corneal surface anterior posterior chambers 42 fresh porcine eyes. Twenty-one eyes scanned comparing axial helical imaging. remaining 21 using CT after implantation a simulated human skull before placement blood chamber (hyphema).RESULTS. Detection rates 57.1% for 41.3% 11.1% T1-weighted imaging (n = 63 fragments). Results significant (p < 0.0001). Sonography detected 43% fragments posterior...
