Noncontrast-enhanced magnetic resonance angiography (NCE-MRA) methods have been demonstrated in anatomies throughout the body. Previously established NCE-MRA techniques suffered from long scan times or low sensitivity. Advances in hardware and softwa

Background: Early diagnosis is a challenge in the treatment of degenerative disc disease. A noninvasive biomarker detecting functional mechanics of the disc is needed. T1ρ-weighted imaging, a spin-lock magnetic resonance imaging technique, has shown

Degenerative disc disease afflicts nearly 12 million people in the United States. Although a single initiating cause of degeneration has not been identified, early degenerative changes occur in the nucleus pulposus.1,2 Breakdown of the large aggregat

Diagnostic methods and biomarkers of early disc degeneration are needed as emerging treatment technologies develop (e.g., nucleus replacement, total disc arthroplasty, cell therapy, growth factor therapy) to serve as an alternative to lumbar spine fu

T1P OR “SPIN-LOCKED” MRI produces contrast unlike conventional T1-orT2-weighted images. Spin-locking is achieved by the application of a low power on-resonance radiofrequency (RF) pulse to the magnetization in the transverse plane. The resulting
