摘要 目的探讨低剂量胸部CT扫描在艾滋病并发卡氏肺囊虫肺炎(PCP)患者应用的可行性和防护价值。方法对234例艾滋病并发PCP胸部CT检查病例,根据患者体质量指数分组,分别进行常规剂量(自动毫安秒)、低剂量(20—50mAs)扫描,盲式阅片评判两种扫描剂量图像对病变诊断、图片质量的差异,结果进行统计学分析。结果当毫安秒从常规剂量减低后,辐射剂量显著降低,CTDIvol从4.27—12.84mGy降低到1.03~2.57rnGy,为原来剂量的12.08%~26.51%。对照常规剂量组的诊断结果,低剂量组均能明确诊断,无一例漏诊或误诊。图像质量在常规剂量以优质片为主,低剂量以优和良为主。结论对近期收治的234例艾滋病并发PCP患者,进行常规剂量胸部CT扫描和低剂量胸部CT扫描.比较成像效果,得出低剂量胸部CT扫描既不影响PCP的诊断,又能显著降低扫描剂量,具有显著的防护价值。
