Is ureteral calculi detection using low dose computerized tomography protocols compromised in overweight and underweight patients?
The sensitivity and specificity for the detection of ureteral calculi on computerized tomography were decreased for underweight and overweight subjects when using extremely low dose radiation settings (less than 1 mSv). Low dose protocols of 15 mAs (2 mSv) can still be used for these subjects without jeopardizing the ability to identify ureteral stones.
Satisfactory results may be obtained after late repair of orbital floor blow-out fractures. Silicone implant has the potential to be used successfully in orbital floor fractures.
