This audit describes ionizing and non-ionizing diagnostic imaging at a regional trauma centre. All 144 patients (males 79.2%, median age 31 years) met with trauma team activation from 1 January 2015 to 31 December 2015 were included. We used data from electronic health records to identify all diagnostic imaging and report radiation exposure as dose area product (DAP) for conventional radiography (X-ray) and dose length product (DLP) and effective dose for CT. During hospitalization, 134 (93.1%) underwent X-ray, 122 (84.7%) CT, 92 (63.9%) focused assessment with sonography for trauma (FAST), 14 (9.7%) ultrasound (FAST excluded) and 32 (22.2%) magnetic resonance imaging. One hundred and sixteen (80.5%) underwent CT examinations during trauma admissions, and 73 of 144 (50.7%) standardized whole body CT (SWBCT). DAP values were below national reference levels. Median DLP and effective dose were 2396 mGycm and 20.42 mSv for all CT examinations, and 2461 mGycm (national diagnostic reference level 2400) and 22.29 mSv for a SWBCT.

1 级创伤中心人群中的诊断成像和电离辐射暴露与创伤团队激活：为期一年的患者记录审核。

该审核描述了区域创伤中心的电离和非电离诊断成像。2015 年 1 月 1 日至 2015 年 12 月 31 日期间，所有 144 名患者（男性 79.2%，中位年龄 31 岁）都参加了创伤小组活动。我们使用来自电子健康记录的数据来识别所有诊断成像，并将辐射暴露报告为常规射线照相 (X 射线) 的剂量面积乘积 (DAP) 和 CT 的剂量长度乘积 (DLP) 和有效剂量。住院期间，134 人（93.1%）接受了 X 光检查，122 人（84.7%）CT，92 人（63.9%）外伤超声聚焦评估（FAST），14 人（9.7%）超声（排除 FAST）和 32 人（22.2%） ) 磁共振成像。116 人（80.5%）在创伤入院期间接受了 CT 检查，144 人中有 73 人（50.7%）进行了标准化全身 CT（SWBCT）检查。DAP 值低于国家参考水平。所有 CT 检查的中位 DLP 和有效剂量为 2396 mGycm 和 20.42 mSv，SWBCT 为 2461 mGycm（国家诊断参考水平 2400）和 22.29 mSv。
