Abstract

81 patients with masses in the nasopharynx were examined by MRI and CT. In cases of primary lesions of the nasopharynx (such as carcinomas and fibromas), MRI with Gd-DTPA was superior to CT. Secondary tumors involving the nasopharynx were visualized equally well with MRI with Gd-DTPA and CT. The results show that MRI should be the primary method of examination in lesions of the nasopharynx. CT is a secondary procedure useful for showing small areas of bone erosion. MRI with the paramagnetic contrast medium Gd-DTPA permits differentiation between inflammatory, cystic and neoplastic masses.

摘要

81例鼻咽部有肿物的患者接受了MRI和CT检查。对于鼻咽部原发性病变（如癌和纤维瘤），使用钆喷酸葡胺（Gd-DTPA）的MRI优于CT。对于累及鼻咽部的继发性肿瘤，使用钆喷酸葡胺（Gd-DTPA）的MRI和CT显示效果相当。结果表明，MRI应作为鼻咽部病变的主要检查方法。CT是一种辅助检查方法，有助于显示小面积的骨质侵蚀。使用顺磁性造影剂钆喷酸葡胺（Gd-DTPA）的MRI可区分炎性、囊性和肿瘤性肿物。
