  Purpose

In this study, we will use advanced and newly available MR imaging techniques at 3 Tesla (including in situ axial loading and quantitative T1rho, T2, and diffusion measurements) to assess the intervertebral discs and adjacent vertebrae in patients with lumbar back pain scheduled for back surgery (n=20), patients with degenerative disease without classic discogenic back pain (n=10), patients who had discectomies for herniated discs (n=5), and age-matched volunteers without back pain (n=10). In all patients standard imaging procedures will also be performed, including radiographs, standard MRI at 1.5 Tesla and discography. All patients will have specimen of the intervertebral disc harvested at surgery and pathologic analysis and spectroscopy of these specimen will be performed. Post-surgical findings/outcome combined with discography will serve as a standard of reference for the identification of the painful disc(s). The diagnostic performance of the new techniques in assessing the painful disc will be evaluated. We will collect disc specimens from 50 patients undergoing back surgery but did not have pre-surgical MR imaging. These disc specimens will be analyzed in the same manner as the specimens collected from surgical patients who had pre-surgical MRI. This study will serve as a pilot study for a larger project focusing on advanced imaging of the painful intervertebral disc.

We hypothesis that advanced, dedicated MR examinations at 3T can identify painful degenerated discs in patients with chronic lumbar back pain.

Biospecimen Retention:   Samples Without DNA

Disc specimens are taken out during back surgery and will be studied using techniques for tissue analysis to explain the properties and characteristics of disc tissue from patients with back pain.

Groups/Cohorts Assigned Interventions
1
Patients with lumbar back pain scheduled for back surgery.
 Device: Magnetic Resonance Imaging
All study subjects will have a 3T MRI examination. The MRI exam will take approximately 90 minutes to complete and will involve the scanning o the spine.
2
Patients with degenerative disease without classic discogenic back pain
 Device: Magnetic Resonance Imaging
All study subjects will have a 3T MRI examination. The MRI exam will take approximately 90 minutes to complete and will involve the scanning o the spine.
3
Normal control without back pain.
 Device: Magnetic Resonance Imaging
All study subjects will have a 3T MRI examination. The MRI exam will take approximately 90 minutes to complete and will involve the scanning o the spine.
4
Post Surgical discectomy patients
 Device: Magnetic Resonance Imaging
All study subjects will have a 3T MRI examination. The MRI exam will take approximately 90 minutes to complete and will involve the scanning o the spine.
5
disc specimens
 Device: Magnetic Resonance Imaging
All study subjects will have a 3T MRI examination. The MRI exam will take approximately 90 minutes to complete and will involve the scanning o the spine.

  Eligibility

Ages Eligible for Study:   25 Years to 60 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   Yes
Sampling Method:   Non-Probability Sample
Study Population

Potential subjects are patients seen by surgeons in the UCSF ACC Orthopedic Clinic. If a patient meets all inclusion and exclusion criteria, the orthopedic surgeon will talk to the patient about the new dedicated examinations using 3 Tesla MRI that can identify painful degenerated discs. When patient is comfortable with participating and has made a decision to go ahead with the MRI, patient can let the orthopedic surgeon's assistant know about his/her decision, the assistant will make sure that patient still meets the inclusion and exclusion criteria and will call the coordinator at the Imaging Center to set up an MRI appointment.

Flyers will be posted at different UCSF campuses to recruit for normal age-matched and young normal volunteers.

Criteria

Inclusion Criteria for Patient with classic discogenic back pain:

  • age range 25-60 years old
  • Back and/or leg (back>leg) pain
  • Degenerative disc disease in one or more adjacent vertebral levels between L3-S1
