Purpose: To compare diagnostic efficiency of USG and MR in orbital diseases.
Material and methods: The clinical material comprised 25 cases of various orbital changes, mostly tumor-like, examined between January 1994 and March 1995 using USG and MR. The value of both methods was compared as well as the results of histopathological studies performed in 15 eyes. Four selected cases are presented in details.
Results: In most cases proper diagnosis was state basing both on USG and MR examinations. In 2 cases of USG examination and in 2 of MR misdiagnosis was state as compared with histopathological results. In small tumors and those localised in the anterior part or apex of the orbit MR gives better images.
Conclusion: USG and MR are complementary diagnostic methods of orbital soft tissue changes, very efficient if made by an experienced examiner.
