本文将 MRI 与 CT 进行比较,探讨其在肺癌病期诊断方面的价值。47名肺癌患者经 CT 及 MRI 诊断,鳞癌18例,腺癌11例,小细胞癌7例,大细胞癌6例,未分化癌5例。原发灶皆经细胞学、组织学确诊。应用第三代 CT 装置,静脉注射造影剂前后间隔 8mm 连续扫描。MRI 机为西蒙斯公司Magnetom(0.5特斯拉超电导型)。 This article compares MRI with CT and discusses its value in the diagnosis of lung cancer. 47 lung cancer patients were diagnosed by CT and MRI. There were 18 squamous cell carcinomas, 11 adenocarcinomas, 7 small cell carcinomas, 6 large cell carcinomas, and 5 undifferentiated carcinomas. The primary lesions were confirmed by cytology and histology. With the third-generation CT device, continuous contrast scans were performed at intervals of 8 mm before and after intravenous contrast administration. The MRI machine was Simmons Magnetom (0.5 Tesla superconductivity type).
