T1ρ Magnetic Resonance Imaging and Discography Pressure as Novel Biomarkers for Disc Degeneration and Low Back Pain

T1ρ MRI and Discography Opening Pressure are Quantitative Biomarkers of Disc Degeneration In Vivo

INTRODUCTION –A quantitative assessment of disc health is essential for selection of treatment options and to the future of biomedical research in the development of new spine technologies. The Pfirrmann grade determined from T2 MRI is currently the gold standard to determine disc degeneration [1]. This method has been valuable for research, yet is extremely limited as it is not a continuous qu...

Multimodal quantitative magnetic resonance imaging for lumbar intervertebral disc degeneration

The present study investigated the application of the T1ρ and T2 relaxation mapping magnetic resonance imaging (MRI) and diffusion-weighted imaging (DWI) in the evaluation of intervertebral disc degeneration (IDD). A total of 93 asymptomatic subjects were imaged with T1ρ and T2 mapping, as well as DWI. Pfirrmann grading was performed and correlation analysis was conducted for T1ρ, T2 and DWI re...

Repeated Imaging for Diagnosis of Low Back Pain

Magnetic resonance imaging findings in low back pain and lower extremity radicular chronic pain

Background: Low back pain (LBP) is one of the most prevalent complaints among the people worldwide. According to the medical statistics, about 80 percent of people have at least one episode of LBP during their lifetime cause them to visit a physician for treatment. LBP is the most prevalent cause of work disability and its related leaves among people under 45 years old. Numerous studies have be...
