CT值在老年性胸膜疾病诊断中的意义

THE CT SCAN VALUE FOR PLEURAL DISEASES IN THE ELDERLYS

目的 探讨CT值评价胸膜疾病的实用性.方法 50例胸膜疾病患者作CT检查时屏气,连续动态从肺尖至肺底作扫描,每层厚1cm,在5秒内完成.50例健康老人对照.结果 胸腔积液;漏出液<18±2Hu、渗出液>18±2Hu、血性液 30～50Hu、乳糜液28Hu、脓胸20～40Hu、气胸-100--200Hu,肺部肿块30～70Hu、结核钙化90～110Hu,胸膜增厚20～30Hu,胸膜肿瘤30～50Hu,胸膜结节40～6OHu.结论 临床应用CT值对胸膜疾病的诊断有一定的实用价值.

ve To evaluate the value of CT scan in diagnosing pleural diseases. Methods There were 50 elderly cases with Pleural disease and 50 healthy cases as control. Patient hold his or her breath for 5 sec-onds while the CT scanning of lung was taken from top to bottom at 1.0 cm. interval. Results The values of CT scan were: pleural transudate < 18±2 Hu, pleueal exudate > 18±2 Hu, pleural effusion, blood stained 30 - 50 Hu, chylothorax 28 Hu, pyothorax 20 - 40 Hu, pneumothorax - 200 - -100 Hu, pulmonary solitary mass 30-70 Hu, tuberculous calcification 90 - 110 Hu, pleural thickening 20-30 Hu, pleueal nodule 40-60 Hu, and pleural neoplasm 30 - 50 Hu. Conclusions CT scan has certain practical value for clinical use on diagnosing el-derly pleural diseases.
