【摘要】 目的:对比观察常规CT与螺旋CT在肺癌诊断中的CT表现特征。方法:经病理证实的肺癌患者134例,中心型肺癌56例,周围型肺癌78例。所有病例均经常规CT或螺旋CT扫描,观察其CT表现特征,并对其进行比较。结果:56例中心型肺癌中,病变发生于右侧支气管30例,左侧支气管26例;螺旋CT扫描对肺癌阻塞性改变及纵隔内大血管受侵情况的显示率高于常规CT扫描,对病灶密度、肺门及纵隔淋巴结转移等方面的观察与常规CT扫描相比无明显差别。78例周围型肺癌中,发生于右肺者34例,左肺者44例;螺旋CT扫描对病灶内钙化、空泡、空气支气管、空洞及病灶局部胸膜凹陷等征象均优于常规CT。结论:螺旋CT对中心型肺癌所引起的继发性改变及病变对肺门、纵隔大血管侵犯的发现率较高,对周围型肺癌病灶内各征象均有较高的检出率明显优于常规CT扫描。更多还原

【Abstract】 Objective:To observe and compare the findings of lung cancer with conventional CT and spiral CT. Methods:One hundred and thrity-four cases of pathologically confimed lung cancer, including 56 centrally located and 78 peripherally located lung cancer, were examined by conventional CT and spiral CT, and their findings compared. In 30 of the 56 cases with central lung cancer, the leaon was located in the right bronchus and in 26 cf them the leaon was in the left bronchus. On spiral CT, the display rate of obstructive findings and invasion to tug vessels in the mediastinum was higher than that on conventional CT. There was noremarliable difference in density of the leaon and detection of metastasis in hilar and mediasdnal lymph nodes between conventional and spiral CT. In 34 cf the 78 cases with peripheral lung cancer, the leaon was in the right lung and in 44 was the lesion in the left lung. Calcification, airlmonchogram, cavity and pleural indentation cf the lesion in the peripheral lung cancer were better delayed by spini than by conventional CT. Conclusion:Spiral CT is superior to conventional CT in the observation of agns characteristic of central and peripheral lung cancers.更多还原
