摘要
目的评价增强技术在胸部病变CT引导经皮切割针穿刺活检中的应用价值。方法收集河南省胸科医院2011年1月—2014年5月资料完整的671例行CT引导经皮切割针穿刺活检术病例,其中524例术前行CT平扫(A组),147例术前行CT增强(B组),总结平扫和增强技术分别在胸部病变CT引导下经皮切割穿刺活检术对的取材成功率、诊断准确性、肿瘤灵敏性、阳性预测值、假阴性率及主要并发症的发生率,并进行对照。结果二者取材成功率(P<0.01)、诊断准确性(P<0.01)、肿瘤灵敏度(P<0.01)、出血发生率(P<0.05)有统计学差异,阳性预测值、假阴性和气胸发生率无统计学差异(P>0.05)。结论增强技术有助于提高CT引导经皮切割针胸部活检的取材成功率,肿瘤诊断准确率、灵敏性,同时并降低出血并发症的发生率。
Objective To explore the value of contrast - enhanced scan technique in guiding percutaneous chest biopsy Puncture. Methods Retrospective analysis of 671 patients with complete clinical data , who underwent CT - guided percutaneous chest biopsy Puncture since the Jan 2011 to the May 2014. These biopies were guided either by non -contrast CT（ group A） , or Contrast -enhanced CT in 114 patients （group B）, and the success rate of biopsy , the diagnostic accuracy, tumor sensitivity, positive predictive value, false - negative rate and incidence of complication were compared. Results Statistics shows that the positive predictive value, false - negative rate of tumor and pneumothorax rate have no significant difference ,while the success rate of puncture（ P 〈 0. 01 ） , diagnostic accuracy（ P 〈 0. 01 ） , sensitivi- ty of tumor（P 〈 0. 01 ）, hemorrhage rate （P 〈 0. 05 ） between the two groups are significantly different. Conclusion Contrastenhanced scan can increase the success rate of puncture, diagnostic accuracy and sensitivity of tumor with lower risk of hemorrhage in CT - guided pereutaneous chest biopsy puncture.
