Abstract
Diagnosing and monitoring of Graves' Orbitopathy (GO) can be supported by use of Ultrasonography (USG) and Computerized Tomography (CT); they provide supplementary information. In this retrospective study we describe 107 clinical GO patients evaluated by B-scan USG and 27 clinical GO patients evaluated by CT scan. Analysis of 236 B-scan USG included measurements of medial, inferior and lateral rectus muscles. The presence of muscle enlargement and increased orbital fat were noted by the radiologist on 27 CT scans. Sensitivity of both B-scan USG and CT scan were calculated. We suggest that B-scan USG has a high sensitivity, which is equal or better than CT scan sensitivity in diagnosing GO. Furthermore USG A and B scan combination is an effective, accurate tool in diagnosing GO, and optic neuropathy, but it also provides essential information about the GO disease activity.
