Feasibility of a Synthetic MR Imaging Sequence for Spine Imaging

Lumbar spine: reliability of MR imaging findings.

PURPOSE To characterize the inter- and intraobserver variability of qualitative, non-disk contour degenerative findings of the lumbar spine at magnetic resonance (MR) imaging. MATERIALS AND METHODS The case accrual method used to perform this institutional review board-approved, HIPAA-compliant retrospective study was the random selection of 111 interpretable MR examination cases of subjects ...

Extraspinal findings on lumbar spine MR imaging.

Interpretation of radiologic studies requires vigilance on the part of the radiologist to identify findings and abnormalities outside the region of interest. In the case of routine lumbar spine MRI for low back pain, many extraspinal abnormalities can often be identified. Some of these findings may account for low back pain. Other findings are incidental, but may have significant clinical impli...

Update on MR imaging of spondyloarthritis. part two: spine MR imaging.

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

Lumbar spine: motion compensation for cerebrospinal fluid on MR imaging.

To determine whether the motion of cerebrospinal fluid (CSF) in the lumbar spine degrades T2-weighted magnetic resonance (MR) images, a spine phantom, three healthy volunteers, and a prospective series of 20 patients suspected of having lumbar spine disease underwent MR imaging with and without motion-compensation techniques. In the phantom, pulsation amplitudes as low as 3 mm (within the physi...
