【摘要】：目的探討MRS技術(shù)定量評價腰椎間盤退變程度的價值。方法對82例腰痛患者行腰椎MR常規(guī)掃描,采用T2WI矢狀位圖像進(jìn)行Pfirrmann分級;采用MRS技術(shù)檢測腰椎間盤髓核的氮-乙酰氨基(N-acetyl)峰下面積、水(Water)峰下面積及二者峰下面積比值,分析MRS測量值與Pfirrmann退變分級、患者年齡間的相關(guān)性。結(jié)果 82例患者中,204個椎間盤可獲得MRS測量值,其中Ⅱ、Ⅲ、Ⅳ、Ⅴ級椎間盤數(shù)目分別為89個、73個、39個、3個,髓核區(qū)N-acetyl峰下面積、Water峰下面積、N-acetyl/Water峰下面積比值與腰椎間盤Pfirrmann分級呈負(fù)相關(guān)(r_s=-0.460、-0.204、-0.526,P均0.05)。30歲、30~39歲、40~49歲、50~59歲、59歲的患者中,取得MRS測量值的椎間盤數(shù)目分別為62個、25個、37個、51個、29個,腰椎間盤髓核區(qū)N-acetyl峰下面積、N-acetyl/Water峰下面積比值與年齡段呈負(fù)相關(guān)(r_s=-0.247、-0.385,P均0.05)。結(jié)論 MRS技術(shù)可用以定量檢測腰椎間盤的退變程度。
[Abstract]:Objective to evaluate the value of MRS technique in quantitative evaluation of lumbar disc degeneration. Methods 82 patients with low back pain underwent routine lumbar MR scanning, Pfirrmann grading was performed with T2WI sagittal image, and the area under the N-acetyl peak, water (Water) peak area and the ratio of the two subpeak areas in the nucleus pulposus of lumbar intervertebral disc were detected by MRS technique. To analyze the correlation between MRS measurement and Pfirrmann degeneration grade, age of patients. Results among 82 patients, 204 intervertebral discs were measured by MRS. The numbers of 鈪，
