摘要目的通过对上海市所有辖区内公立医疗机构CT设备常见扫描部位的剂量参数调查，分析上海地区成人CT扫描剂量分布，为建立上海市CT扫描诊断参考水平提供依据。方法在上海所有辖区（共16个区）分别选取至少1家开展CT放射诊疗的医疗机构，每家医疗机构抽取1台年度状态检测合格的CT设备开展头颅、胸部、腹部、腰椎扫描受检者进行剂量调查，收集受检者基本信息、CT扫描参数、容积CT剂量指数(CTDI_vol)和剂量长度乘积（DLP）等剂量指标。结果共收集1475例CT受检者扫描数据，头颅、胸部、腹部和腰椎的CTDI_vol的75%位数分别为57 mGy、11 mGy、16 mGy和23 mGy；DLP的75%位数分别为862 mGy·cm、361 mGy·cm、593 mGy·cm和550 mGy·cm。结论不同扫描部位的CTDI_vol和DLP存在显著差别，相同部位扫描的CTDI_vol和DLP也存在较大差异，男性DLP略高于女性。
