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.
摘要
一项关于眼眶肿瘤的磁共振成像（MRI）、计算机断层扫描（CT）和超声检查的对比研究表明，仅对于恶性黑色素瘤和眼眶假瘤，MRI具有最大的诊断相关性。恶性黑色素瘤因其特征性的T1和T2信号强度可与血肿相鉴别。MRI受检查时间长以及运动伪影导致图像质量下降的风险影响。
