【摘要】：目的評(píng)價(jià)MRI T2 mapping成像技術(shù)對(duì)腰椎間盤退行性變的診斷價(jià)值。資料與方法前瞻性納入2013年10月-2015年12月因腰背部疼痛于復(fù)旦大學(xué)附屬上海市第五人民醫(yī)院就診并行腰椎1.5T MRI檢查的患者100例。常規(guī)矢狀位T1WI及T2WI、橫斷位T2WI,并行正中矢狀位T2 mapping成像。根據(jù)Pfirrmann標(biāo)準(zhǔn)將475個(gè)腰椎間盤分級(jí),測(cè)量髓核(NP)及纖維環(huán)(AF)前、后緣的T2值。分別比較各級(jí)NP和AF前、后緣T2值,并分析T2值、年齡以及分級(jí)間的相關(guān)性。同時(shí)選取30例患者間隔半年行第2次MRI檢查,比較前后2次椎間盤T2值的差異。結(jié)果腰椎間盤各分級(jí)NP的T2值除IV級(jí)與V級(jí)間差異無(wú)統(tǒng)計(jì)學(xué)意義(P0.05)外,其余各級(jí)間差異均有統(tǒng)計(jì)學(xué)意義(P0.05);腰椎間盤NP T2值與各分級(jí)呈高度負(fù)相關(guān)(r=-0.77);30例腰痛患者間隔半年測(cè)得椎間盤AF前、后緣及NP T2值間差異均無(wú)統(tǒng)計(jì)學(xué)意義(P0.05)。結(jié)論 T2 mapping成像技術(shù)能夠定量評(píng)估腰椎間盤退行性變程度,尤其是NP的T2值能夠較好地反映Ⅰ~Ⅳ級(jí)椎間盤退行性變程度的差異,因而可以為診斷腰椎間盤退行性變提供影像學(xué)依據(jù)。
[Abstract]:Objective to evaluate MRI T2. Mapping imaging technique in the diagnosis of lumbar intervertebral disc degeneration. Data and methods data and methods prospectively included in Shanghai affiliated to Fudan University from October 2013 to December 2015 due to lumbar and back pain. Five people's Hospital with Lumbar vertebrae 1.5T. The sagittal T1WI and T2WI were performed in 100 patients with MRI. Transverse T _ 2WI was performed and T _ 2 mapping was performed on the median sagittal position. 475 lumbar intervertebral discs were graded according to Pfirrmann criteria. The T _ 2 values of the nucleus pulposus (NPN) and the anterior and posterior edge of the nucleus pulposus were measured. The T _ 2 values before and after NP and AF were compared and analyzed respectively. The correlation between age and grade. At the same time, 30 patients were examined with MRI for the second time half a year. Results the T2 value of each grade of lumbar intervertebral disc was not significantly different between grade IV and grade V (P 0.05). The differences among other levels were statistically significant (P 0.05). The NP-T2 value of lumbar intervertebral disc was negatively correlated with each grade. The intervertebral disc AF was measured in 30 patients with low back pain at intervals of six months. There was no significant difference between the posterior margin and NP T2. Conclusion T2 mapping imaging can quantitatively evaluate the degenerative degree of lumbar intervertebral disc. Especially, the T2 value of NP can reflect the difference of degenerative degree of intervertebral disc between grade 鈪，
