PLoS Med:胸部创伤,CT扫描区域可以减小

2015-10-09 赵洲 译 MedSci原创

 在过去的二十年中,CT技术已经越来越多地用于成年人钝性创伤评价诊断,许多创伤中心采用常规的从头到骨盆的CT扫描。许多研究已经表明CT使用的延长和癌症风险有关。目前,许多专业机构已经呼吁对创伤CT诊断进行评价。对于有效的放射剂量,胸部CT的致癌风险相当大。此外,不必要的创伤胸部CT也可能会导致不必要的医疗花费。此前研究表明,在进行X光检查后进行胸部CT是一项低产出的事情,这导致了超过20

在过去的二十年中,CT技术已经越来越多地用于成年人钝性创伤评价诊断,许多创伤中心采用常规的从头到骨盆的CT扫描。许多研究已经表明CT使用的延长和癌症风险有关。目前,许多专业机构已经呼吁对创伤CT诊断进行评价。对于有效的放射剂量,胸部CT的致癌风险相当大。此外,不必要的创伤胸部CT也可能会导致不必要的医疗花费。此前研究表明,在进行X光检查后进行胸部CT是一项低产出的事情,这导致了超过20万美元的浪费并且每23个创伤诊断患者中可能有一个会被诱发癌症。


为了引出和确证钝性创伤诊断中的选择性胸部CT的两种决策仪器(DI),研究人员进行了为期三年的多中心、前瞻性观测试验。受试者都是年龄在14岁以上。在第一阶段,医生记录了在查看胸部成像结果前的14项临床条件存在与否。研究人员通过CT放射学和根据临床分类指标对受伤程度进行分类,从而确定最终的受伤结果。采用两种递归分区导出两种DI:胸部全CT和胸部主要CT。在随后的确证阶段,使用类似的方法对两种方法进行前瞻性检测。不过有的医生认为这项工作仍有局限性,比如创伤分类和检测的敏感度阈值。

通过此项研究,引出并且确证了两种DI,这减少了不必要胸部CT的使用。既节省了患者的医疗花费,又使得患者患癌风险降低,可谓是一举两得。

JCO:又一早期肺癌生物学标志物---diacetylspermine被发现

Science Daily:又一早期肺癌生物标志物的发现尽管几十年以来一直在宣传吸烟的害处,但是肺癌仍是美国第二大常见的癌症,同时也是因癌死亡的最常见病因。通常患者确诊肺癌时,病情已处于晚期,治疗十分困难。来自加州大学戴维斯分校代谢组学中心的研究人员正尝试通过确定肺癌早期的生物学标志物以改变这一状况。早期诊断是肺癌治疗的关键,对高危人群进行定期的低剂量CT扫描可早期诊断肺癌,但是行这些检查所需的费

GE医疗近日宣布,该公司开发的低剂量计算机断层扫描(LDCT)肺癌筛查方案(LCS)获得美国FDA批准,这也是FDA批准用于肺癌高危群体筛查的首个低剂量CT解决方案。此次批准同时也标志着FDA首次批准将CT设备用于疾病的筛查。此前,美国预防服务工作组(USPSTF)和医疗保险及医疗补助服务中心(CMS)已推荐符合条件的人群每年进行低剂量CT筛查,同时低剂量CT应作为常规肺癌筛查项目。此外,美国Me

腰椎间盘突出CT和MRI读片技巧
