摘　　要：目的探讨局部病灶团注增强CT引导下经皮肺穿刺活检术的临床应用价值。方法回顾性分析160例接受CT引导下经皮肺穿刺活检患者的临床资料,比较局部病灶团注增强CT组与平扫CT在标本获取的满意率、病理阳性率、并发症、平均活检次数、更换穿刺点者所占比例的差异。结果增强CT组和平扫CT组的平均活检次数及更换穿刺点差异有统计学意义(P<0.05)。增强CT组和平扫CT组弹簧针取材满意率及病理的阳性率差异有统计学意义(P<0.05)。增强CT组和平扫CT组气胸和出血的发生率差异有统计学意义(P<0.05)。结论局部病灶团注增强CT能够提高穿刺的准确性与安全性,更容易取得病理阳性结果,具有较高的临床应用价值。ObjectiveTo investigate the clinical value of the bolus triggered technique with CT-guided injection in percutaneous biopsy of lungs. MethodsWe retrospectively analyzed the clinical data of 160 cases of patients undergoing CT guided percutaneous lung biopsy. The difference between the bolus triggered technique with CT-guided injection and plain CT scan in the rate of satisfaction with sampling, the positive rate of pathology, complications, the average times of biopsy and in the percentage of patients with changed puncture points was compared. ResultsThere was statistically significant difference between the two approaches in terms of average times of biopsy and locations of puncture points（P〈0.05）. The difference in the rate of satisfaction with sampling via spring needles and the positive rate of pathology was statistically significant between the two CT scan methods（P〈0.05）, so was the difference in the incidence of pneumothorax and bleeding（P〈0.05）. Conclusion The bolus triggered technique with CT-guided injection in percutaneous biopsy of lungs can improve the accuracy and safety of puncture, make pathological positive results more accessible, and is of high clinical value.
