Lumbar Intervertebral Disk Degeneration and Patient Age
N.L. Marinelli V.M. Haughton P.A. Anderson BACKGROUND AND PURPOSE: T2 relaxation times provide a continuous measure of changes in intervertebral disk biochemistry. The purpose of this study was to correlate T2 relaxation times in lumbar disks with patient age and stage of degeneration. MATERIALS AND METHODS: Sagittal T1and T2-weighted images and axial images were acquired in 20 patients referre...
متن کاملBMI, Abdominal Obesity and Physical Activity in Adult Candidates for Lumbar Disk Degeneration Surgery
Background and Aim: Lumbar disc degeneration is one of the most frequent causes of pain in the lower back, and lack of physical activity, overweight and obesity have been regarded as the most significant factors in its occurrence. The present study was conducted with the aim of evaluation of body mass index, abdominal obesity and physical activity level in patients registered for elective lumba...
متن کاملLumbar disk degeneration in spinal dysraphism.
Eight of the 22 patients had spina bifida aperta, and 14 had spina bifida occulta. These included eight cases with repaired myelomeningocele, seven with an intraspinal lipoma and tethering of cord , three with dermal sinuses, and one with diastematomyelia. Bulging and low signal intensity of the nucleus pulposus on T2-weighted images are the criteria for disk degeneration [1 , 2] . In our study...
متن کاملA New 3D Segmentation Methodology for Lumbar Vertebral Bodies for the Measurement of BMD and Geometry
In this paper a new technique is presented that extracts the geometry of lumbar vertebral bodies from spiral CT scans. Our new multi-step segmentation approach yields highly accurate and precise measurement of the bone mineral density (BMD) in different volumes of interest which are defined relative to a local anatomical coordinate systems. The approach also enables the analysis of the geometry...
متن کاملCorrelation study between facet joint cartilage and intervertebral discs in early lumbar vertebral degeneration using T2, T2* and T1ρ mapping
Recent advancements in magnetic resonance imaging have allowed for the early detection of biochemical changes in intervertebral discs and articular cartilage. Here, we assessed the feasibility of axial T2, T2* and T1ρ mapping of the lumbar facet joints (LFJs) to determine correlations between cartilage and intervertebral discs (IVDs) in early lumbar vertebral degeneration. We recruited 22 volun...
