通过对56例鼻源性眼球突出的CT及MRI检查表现分析，认为CT在揭示钙化及骨皮质上优于MRI，但对密度差别不大者如炎症与肿瘤、复发性病变与疤痕组织等不易区分。MRI从多方位显示病变，并可良好揭示软组织结构成分，对炎症、血管瘤、粘液性囊肿、纤维疤痕等可有较特异表现，CT对揭示骨结构明显优于磁共振。确定诊断必须结合临床表现，必要时两者联合应用，提高诊断正确率。
Through the CT and MRI examination of 56 cases of nasal exophthalmos, it is considered that CT is superior to MRI in revealing calcification and cortical bone, but it is not easy to distinguish between low density such as inflammation and tumor, recurrent lesion and scar tissue distinguish. MRI showed lesions from multiple directions and could well reveal the structural components of soft tissue. Inflammation, hemangiomas, mucinous cysts and fibrous scars may be more specific manifestations of MRI. CT revealed that bone structure was superior to MRI. Determine the diagnosis must be combined with clinical manifestations, if necessary, the two jointly applied to improve the diagnostic accuracy.
