目的通过收集病理学证实为中央型肺癌的病例,分析其在双排螺旋CT平扫的表现特点,以期提高CT平扫对该病的诊断准确率.方法回顾性分析57例经支气管纤维镜检查或CT引导下肺活检病理证实为中央型肺癌的CT表现,其中,男41例,女16例,年龄44～86岁,平均(65±3)岁.全部病例均为双排螺旋CT平扫,再对局部兴趣区进行薄层重建.结果病理学诊断的57例病例中,腺癌24例,鳞癌27例,透明细胞癌6例.经CT扫描诊断后,肿瘤最大径≤3 cm者11例,＞3cm者46例.支气管管腔狭窄者29例,支气管闭塞者24例.54例确诊为肺癌,3例误诊为其他疾病,双排螺旋CT方法与病理学诊断符合率为95％.结论双排螺旋CT平扫后再对局部兴趣区进行薄层重建,对于提高中央型肺癌诊断准确率具有较高的临床价值.

Objective To improve the diagnosis accuracy rate of CT scan for central type carcinoma of lung analyzing the features of double row spiral CT scan in the patients pathologically confirmed with central type carcinoma.Methods The CT features of 57 patient with central type carcinoma of lung pathologically confirmed via bronchofiberscope examination or CT guided lung biopsy were retrospectively analyzed.Among the 57 patients,32 were male and 25 female;they were 44-86 years old,with a mean age of (65 ± 3) years.All cases were scanned with double row spiral CT.Thin slice reconstruction was carried out on the some interested regions.Results Among the 57 cases,24 got adenocarcinoma,27 squamous cell carcinoma,and 6 clear cell carcinoma.The CT scan showed that 11 cases' tumor maximum diameters were less than or equal to 3 cm and 46 cases' more than 3 cm;29 got bronchial stenosis and 24 bronchial obstruction;54 were diagnosed with lung cancer and 3 misdiagnosed with other diseases,with an accordance rate of 95％.Conclusion Thin slice reconstruction of some interested regions after double spiral CT scan can improve the clinical diagnostic accuracy of central type carcinoma of lung.
