超声与CT经皮穿刺在超声可视性胸部病变定性诊断中的对比研究

目的 比较彩色超声(彩超)与CT经皮穿刺在超声可视性胸部病变定性诊断中的病灶刺中率、病理诊断阳性率以及并发症发生率.方法 回顾2015年1月至2016年6月影像学资料提示超声可视性胸部病变患者112例,病变与皮肤之间无骨骼及肺气遮挡,其中经超声引导下穿刺52例(超声组),经CT引导下穿刺60例(CT组),比较两组的病灶刺中率、病理诊断阳性率及并发症发生率.结果 超声组刺中率100％ (52/52),高于CT组91.7％ (55/60),超声组病理诊断阳性率为96.2％ (50/52),高于CT组80.0％ (48/60),超声组并发症发生率3.8％(2/52),低于CT组18.3％(11/60).结论 对于超声可视性胸部病变,超声引导下的穿刺活检较CT更加可靠.

Ultrasound-guided versus CT-guided percutaneous biopsy for the qualitative diagnosis of ultrasonic-visual chest lesions: a comparison study

Objective To compare the puncturing hit rate,positive rate of pathological diagnosis and the incidence of complications between color Doppler ultrasound-guided and CT-guided percutaneous biopsy for the qualitative diagnosis of ultrasonic-visual chest lesions.Methods A total of 112 patients,who were encountered from January 2015 to June 2016 in authors' hospital and whose imaging materials suggested the presence of ultrasonic-visual chest lesions,were enrolled in this study.There were no bones or lung air between the thoracic skin and chest lesion to hinder imaging observation.Ultrasound-guided puncturing was employed in 52 patients (ultrasound-guided group) and CT-guided puncturing was adopted in 60 patients (CT-guided group).The puncturing hit rate,positive rate of pathological diagnosis and the incidence of complications were compared between the two groups.Results The puncturing hit rate in ultrasound-guided group was 100％ (52/52),which was higher than 91.7％ (55/60) in CT-guided group.The positive rate of pathological diagnosis in ultrasound-guided group was 96.2％ (50/52),which was higher than 80.0％ (48/60)in CT-guided group.The incidence of complications in ultrasound-guided group was 3.8％ (2/52),which was lower than 18.3％(11/60) in CT-guided group.Conclusion For the qualitative diagnosis of ultrasonic-visual chest lesions,ultrasound-guided percutaneous biopsy is more reliable than CT-guided percutaneous biopsy.
