简要总结
1-standardization of semi quantitative muscle ultrasonographic parameters ( muscle thickness (MT) and echo intensity (EI) ) in healthy adults and to obtain a set of normal values of all accessible muscle in both upper and lower limbs.
2.standardizaition of quantitative muscle ultrasonographic parameters (Gray scale level (GSL), Calibrated muscle backscatter values (cMBs), Optical Density (OD), 2D Textu1) in healthy adults and to obtain a set of normal values of all accessible muscle in both upper and lower limbs.
详细描述
. Ultrasound is a widely used imaging technique in many different medical specialties. It is a non-invasive, safe and relatively cheap investigation method.
Ultrasound is a non-invasive method to quantitatively measure various muscle parameters.
Ultrasound imaging (US) has shown to be capable of visualizing normal and pathological skeletal muscles.(1) By measuring muscle thickness (MT) and echo intensity (EI) (=grey-value) of the muscle, structural changes caused by neuromuscular disorders can be detected. (2, 3, 4) Quantitative evaluation of US images is preferable over visual evaluation, because it is more sensitive and objective and offers the possibility to perform statistical analysis.(5) A prerequisite for the diagnostic use of quantitative muscle US is the availability of normal reference values.
Ultrasonography can detect structural muscle changes caused by neuromuscular disease. Quantitative analysis is the preferred method to determine if ultrasound findings are within normal limits, but normative data are incomplete.(6)
