The diagnosis of herniated intervertebral disks with MR imaging: a comparison of gradient-refocused-echo and spin-echo pulse sequences.
Axial MR images of 65 lumbar disks with herniated nucleus pulposus imaged by gradient-refocused-echo (GRE) and spin-echo (SE) MR pulse sequences of 200-400/15 with a flip angle of 15-30 degrees was selected as optimal because of its high signal-to-noise ratio and good contrast between CSF, nucleus pulposus, and bone. The GRE technique was confirmed to be more sensitive in detecting prolapsed di...
متن کاملSerial MR Imaging of Annular Tears in Lumbar Intervertebral Disks.
BACKGROUND AND PURPOSE Annular tears of lumbar intervertebral disks are found in both symptomatic and asymptomatic persons; therefore, it is difficult to determine whether these findings indicate acute abnormality. Our purpose was to determine whether the MR imaging findings of tears (ie, hyperintensity and contrast enhancement) of the annulus fibrosus persist or resolve over time. METHODS A ...
متن کاملDiffusion into human intervertebral disks studied with MR and gadoteridol.
PURPOSE To determine the feasibility of measuring diffusion into human intervertebral disks by means of MR imaging with an intravenous nonionic gadolinium complex (gadoteridol). METHODS In 18 patients undergoing lumbar spine MR imaging, signal intensity was measured in the intervertebral disks after a dose of 0.1 mmol/kg and after a supplemental dose of 0.2 mmol/kg. RESULTS Signal intensity...
متن کاملUltrashort Echo Time (UTE) MR Lung Imaging with Respiratory Motion Compensation
Introduction: Conventional gradient-echo based magnetic resonance imaging of lung parenchyma suffers from poor signal-to-noise ratios due to low proton density and short T2* caused by susceptibility gradients between airways and tissue. In addition, respiratory and cardiac motions seriously degrade the achievable image quality. Ultra-short echo time (UTE) MRI has recently gained renewed attenti...
متن کاملAn Independent Multichannel Imaging Research System for Ultrashort Echo Time Imaging on Clinical MR Systems
Most clinical magnetic resonance systems do not have access to ultrashort echo time (UTE) imaging. The aim of this project was to develop a fully independent imaging insert for clinical MR systems to provide this new research application without disturbing routine operation. The initial clinical target for the system was improved orthopedic upper limb imaging using ultrashort repeat and echo ti...
