【摘要】 目的 分析双输入模型 CT 灌注成像(dual-input body CT perfusion imaging,DI-CTP)在肺结节经皮CT穿刺活检中的临床应用价值。方法 收集94例接受DI-CTP引导经皮穿刺活检肺结节患者的临床资料,分析DI-CTP引导肺结节穿刺阳性率及病理诊断准确率,比较DI-CTP引导穿刺活检与肺动脉灌注指数(PI)对肺结节的诊断效能。结果 94例患者中,良性结节30例,恶性结节(周围型肺癌)64例。DI-CTP引导穿刺活检病理诊断准确率为89.36%(84/94),穿刺活检阳性率为96.80%(91/94);DI-CTP引导穿刺活检诊断肺结节的敏感度和特异度均高于PI,差异有统计学意义( χ2=5.83、4.02,均P<0.01)。结论 DI-CTP灌注伪彩图及定量参数分析为肺结节穿刺活检提供了直观影像学依据,提高了肺结节穿刺活检阳性率、病理诊断准确性及鉴别诊断效能。
