Official title
Molecular and Magnetic Resonance Imaging Biomarkers of Facet Joint Pain of the Lumbar Spine With PET/MRI
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Chronic pain incurs over half a trillion dollars in lost productivity (healthcare, lost wages, etc) annually. The most common source is low back pain (LBP), often from facet joints. The clinical evaluation of facet joints is challenging and anatomic imaging findings of facet joint; degenerative change; correlate poorly with pain. Therefore, it is difficult to select appropriate candidate patients/facet joints to treat. Misguided percutaneous treatment can cost thousands of dollars per session and delay diagnoses. Very limited retrospective information suggests that high grade peri-facet MRI signal change correlates to the side of LBP. However, this has not fully characterized the imaging findings and has not correlated to expert clinical exam/percutaneous response, precluding robust and meaningful clinical impact. Minimal retrospective data concludes inflammatory changes can be identified on FDG-PET exams, but the evidence of correlation to patient pain is lacking. Limited DWI exists for inflammatory spondyloarthropathies and myopathies, but is also lacking. This is an exploratory study investigating the utility of FDG PET activity and MRI signal change around facet joints in the clinical management of low back pain. This study will help determine if such imaging biomarkers could change clinical management. Additionally, this will provide data that will be vital to planning a larger prospective study evaluating the ability of imaging biomarkers to predict response to comparison medial branch blocks and RF ablation for treatment of facet joint pain.
