Abstract:
A comparative study of MRI, CT and ultrasound of orbital tumors revealed that only for malignant melanomas and orbital pseudotumors MRI had the most diagnostic relevance. Malignant melanomas could be differentiated from a haematoma due to their characteristic T1 and T2 signal intensity. MRI is impaired by its long examination time and the danger of quality reduction caused by motion artifacts.
