摘要
对活体肌肉非侵入性量化方法比较研究表明:CT有使人体暴露在粒子辐射下的风险;超声波仪便宜,对于肌肉动态影像具有较好的效果,但精度较差,且耗时较长;生物电阻抗仪精度有待提高;MRI技术虽费用高、耗时长,但仍被认为是目前肌肉影像学中一个"金标准"。随着技术的发展,三维超声、全景超声、实时超声等新技术在近几年出现,其图像清晰度接近MRI,应用更广,而CT技术亦被认为是超声和MRI的中和。非侵入性肌肉测量方法是相互补充的。
Comparing for non-invasive quantification methods in vivo muscle by using the method of literature review , com-parative analysis and so on, it shows that CT has the body exposed to particle radiation risks; ultrasonic instrument is cheap and with good results for muscle dynamic image, but has poor accuracy and time consuming;the accuracy of bioelectrical impedance is to be improved.Although the high cost and time-consuming of MRI technology, but it is still considered to be a “gold standard”. With the development, ultrasound has a wider application and appeared close to MRI.New technologies applications of three-di-mensional ultrasound, panoramic ultrasound, real-time ultrasound are still evolving.Yet CT can be viewed as a compromise be-tween these ultrasound （ echocardiography） and MRI.The authors would like to emphasize that Non-invasive Measurement Tech-niques can complement each other.
