诊断试验:

Diagnostic Tests:

金标准或参考标准(即可准确诊断某疾病的单项方法或多项联合方法,在本研究中用于诊断是否有该病的临床参考标准):

磁共振是评价腰椎间盘退变的最主要方法,常规T2加权成像通过髓核(nucIeus pulposus,NP)和纤维环(annulus fibrosus,AF)信号的改变来评价腰椎间盘的退变,采用 Pfirrmann分级法对腰椎间盘进行分级:(1)Ⅰ级:NP 呈高信号且均匀,与 AF 分界清楚,椎间隙高度正常;(2)Ⅱ级:N P 呈高信号,信号不均匀,水平方向低信号条带有或无,与 AF 分界清楚,椎间隙高度正常;(3)Ⅲ级:NP 呈灰色,信号不均匀,与 AF 分界不清楚,椎间隙有或无轻度狭窄;(4)Ⅳ级:NP 呈低信号,信号不均匀,与 AF 界分界模糊不清,椎间隙高度出现轻度或中度狭窄;(5)Ⅴ级:NP 呈黑色,无信号,椎间隙高度重度狭窄。

Gold Standard or Reference Standard (The clinical reference standards required to establish the presence or absence of the target condition in the tested population in present study):

Magnetic resonance is the most important method for evaluating lumbar disc degeneration. Conventional T2-weighted imaging evaluates lumbar disc degeneration through the changes in the signals of the nucleus pulposus (NP) and annulus fibrosus (AF). (1) Grade I: NP was high signal and uniform, clear demarcation with the AF, and normal intervertebral space height; (2) Grade II: NP was high signal, heterogeneous, with or without horizontal low-signal strips, clear demarcation with the AF, and normal intervertebral space height; (3) Grade III: NP was grey, heterogeneous, unclear demarcation with the AF, and mild intervertebral space stenosis; (4) Grade IV: NP was low signal, heterogeneous, unclear demarcation with the AF, and vague intervertebral space height; (5) Grade IV: NP was low signal, heterogeneous, and vague demarcation with the AF, and mild intervertebral space height. (4) Grade IV: NP is low signal, uneven signal, and the boundary with AF is unclear, and the intervertebral space is mildly or moderately narrowed; (5) Grade V: NP is black, no signal, and the intervertebral space is severely narrowed.

指标试验(即本研究的待评估诊断试验,无论为方法、生物标志物或设备,均请列出名称):

采用IVIM-DWI技术作为磁共振定量成像的主要研究手段,在IVIM-DWI图像上分别测量各腰椎间盘髓核的慢速表观扩散系数(ADCslow),快速表观扩散系数(ADCfast)和灌注分数(f值)。

Index test:

The IVIM-DWI technique was used as the main study tool for quantitative magnetic resonance imaging, and the slow apparent diffusion coefficient (ADCslow), the fast apparent diffusion coefficient (ADCfast), and the perfusion fraction (f-value) of the nucleus pulposus of each lumbar intervertebral disc were measured separately on the IVIM-DWI images.
