Brief Summary

Fat infiltration and atrophy of lumbar muscles are related to spinal degenerative conditions, which can be seen reliably on MRI scans of lumbar disc herniation (LDH) patients. The aim of this study was to investigate the relationship between the degeneration of core muscles, obesity and chronic LDH. Fifty-five healthy volunteers and fifty-five chronic LDH patients (the course of the disease is more than six months) were enrolled. Core muscle percent fat and subcutaneous fat tissue thickness(SFTT) were used as the outcome measure, and logistic regression and independent samples t-test as the analytical methods to compare the relationship of the following five independent variables (erector spinae, rectus abdominis, \[transversus abdominal, internal abdominal oblique, and external abdominal oblique muscle\], lumbar multifidus, and psoas major muscles) and SFTT with LDH.

Outcome Measures

Primary Outcomes (1)

  • core muscles percent fat

    Magnetic resonance imaging-guided core muscles percent fat in patients with chronic LDH and healthy volunteers, including erector spinae, rectus abdominis, (transversus abdominal, internal abdominal oblique, and external abdominal oblique muscle), lumbar multifidus, and psoas major muscles was used as the outcome measure

    baseline

Secondary Outcomes (1)

  • Subcutaneous fat tissue thickness

Study Arms (2)

Lumbar disc herniation patients

Diagnostic Test: Magnetic Resonance Hydrolipid Separation Imaging

healthy volunteers

Diagnostic Test: Magnetic Resonance Hydrolipid Separation Imaging

Interventions

MRHS was used to measure different muscle percent fat of core muscles. MRHS, also called Dixon imaging, mainly used the different resonant frequency between the hydrogen nuclei in water and in fat to perform the data acquisition at different echo times (TE). The Dixon sequence basically acquires two images, one image with water and fat signals in-phase and the other with water and fat signals out-of-phase: the sum and subtraction of the two images allow the production of a water-only image and a fat-only image. Scanning equipment: 3.0T superconducting Siemens Skyra Scanner. Scanning parameters: TR5.36ms, TE1.24ms, Flip Angle 9°, number of layers was 44-60, thickness of layer was 5.0 mm, layer interval 1.0mm, FOV50cm×50cm, the scanning time was 12s×5.
