lumbar disc degeneration
Conditions
Interventions
Gold Standard: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 si
(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 uncl
(5) Grade V: NP is black, no signal, and the intervertebral space is severely narrowed.
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 coeff
