新型高性能CT全身扫描只需要40秒

 
高性能计算机断层扫描(CT)能够在40秒之内即可完成整个机体的扫描，能够显示任何病变。这些总体扫描具有广泛的应用范围，从快速完整地检查事故受害者，检测肿瘤转移和关节炎，甚至虚拟尸体解剖，而这对死者家属在感情上更容易接受。

这种新进展令人鼓舞，开拓了新型诊断方法的可能，但是专家警告不可滥用。10年以前，患者接受完整的CT或者核磁共振(MRI)需要数小时之多。那时候扫描时间十分漫长，而且在CT检查时高暴露于放射线。

Total Body Scans Produced in Only 40 seconds
 
High-performance computed tomography (CT) can scan an entire human body in just 40 seconds and is able to show anything that is problematic. These total body scans have a range of applications, from quick, complete examinations of accident victims and the detection of cancerous metastases and arthritis, to new methods of virtual autopsy that are emotionally easier on surviving family members.

This new development is generating excitement and opening up new diagnostic possibilities, yet specialists warn of abuse. Less than 10 years ago, it took several hours to complete a scan on a patient with CT or magnetic resonance imaging (MRI). That was an unreasonably long scan time and in the case of CT entailed very high exposure to radiation.
