腰椎软骨终板的MR三维超短回波时间T2*mapping定量评价
UTE-T2*mapping quantitative evaluation of lumbar cartilage endplate
摘要
Abstract
Objective:To explore the feasibility of quantitative evaluation of lumbar intervertebral cartilage endplate using 3 dimensional multi-echo ultrashort echo time pulse sequence MR imaging. Materials and Methods:The images of lumbar cartilage endplate (CEP) were obtained from twenty one young volunteers by using multi-echo ultrashort echo time pulse sequence, and the image quality were evaluated from grade I to grade III in the order from poor to excellent. The T2*values of both upper and lower CEPs were measured at the lumbar artiifcial color maps from L1/L2 to L5/S1. Results:The 210 CEP images were graded as grade III. The average T2*value of upper and lower CEP was (19.76±8.41) ms, and (30.17±17.25) ms, respectively. The difference of CEP T2*value between upper and lower was statistically signiifcant (t=-5.56, P<0.01). Conclusion:Three dimensional multi-echo ultrashort echo time pulse sequence MR imaging provides an effective approach for the quantitative study of lumbar CEP.关键词
