摘要
目的: 探讨肺结核球的高分辨率CT(HRCT)表现特征及诊断价值.方法:分析21例共24个肺部球形结核灶的HRCT平扫及强化表现,病灶部位用层厚1.5~2.0mm扫描.结果:24个病灶中右肺上叶13个(54.2%),下叶5个(20.8%),左肺上叶6个(25.0%).最大者3.8cm,最小者1.0cm.边缘清楚者18个,不清楚可见毛刺或分叶者6个.周围有卫星灶者16个.密度不均可见钙化者8个.增强扫描无强化者15个,有强化包膜者8个,广泛强化者1个.结论:HRCT能较好的显示结核球的边缘形态及内部密度,增强扫描后密度的变化有助于对该病的正确诊断及鉴别诊断.
Objective To assess the features and the value of diagnosing of HRCT with Pulmonary Spheral Tuberculosis(PST) Methods The 24 foci in 21 patients with PST were analyzed. Thin-sections at 1.5cm to 3.0cm thickness through the nodular center were obtained with plain and enhanced. Results The 13 foci (54.2%) were located in the lobus superior of pulom dexter, 5 foci (20.8%) in lobus inferior. The 6 foci were located (25.0%) in the lobus superior of pulmo sinister. The size of PST was 1.0cm to 3.8cm. The 18 foci were clear of verge and 6 foci were dim. The 16 foci had statllite focus. The 8 foci had calcification. No enhancement had 15 foci. The capsular enhancement had 8 foci. 1 focus showed extensive enhancement. Conclusion HRCT may show the verge and density of preferable. The change of density after enhancement was helpful in diagnosing and differential diagnosis of the PST.
