Abstract:
Silicone oil is used as an intravitreal injection to treat retinal detachment. This material can spread into the subarachnoid space, where it may be mistaken for acute hemorrhage on single-energy computed tomography. This report describes the appearance of intravitreal silicone oil on dual-energy computed tomography, emphasizing unique virtual monoenergetic imaging characteristics that allow for confident differentiation of silicone oil from hemorrhage as well as from other potential single-energy mimics, such as calcium and iodine.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
