10 окт. 2018 г. · Hyperdense left vitreous corresponds to intra-ocular injection of silicone oil used as a means of tamponading the left retina, ... |
The appearance of intraocular silicone oil on CT can potentially mimic orbital pathology, such as vitreous haemorrhage. |
Results: Silicone oil is relatively radiodense; its CT attenuation is approximately 130 HU. On spectroscopy, silicone oil gave a single peak at 0.33 ppm. |
PURPOSE: To describe the CT and MR characteristics of intraocular silicone oil (polydimethylsi- loxane), which is used with increasing frequency to treat ... |
Silicone oil is hyperdense relative to the extraocular muscles but hypodense relative to orbital bone, as seen in a CT scan with the patient in the supine ... |
The high attenuation value of silicone oil on CT and its hyperintensity on T1 weighted MR images may cause diagnostic confusion with haemorrhage. These entities ... |
