新型功能成像技术,如T2/T2*标测、T1ρ计算、T2弛豫时间测量、扩散定量成像、化学交换饱和转移、软骨延迟增强MRI、钠MRI和MR光谱,是有前景的工具,可以根据椎间盘的化学成分评估早期椎间盘退化,主要是通过评估蛋白多糖含量。这些新的MRI技术可能有助于评估椎间盘退变的进展,并在临床试验中具有潜在的应用价值,以评估椎...
In this study, we used kinetic magnetic resonance imaging (kMRI) to investigate the association between degree of facet tropism and amount of disc bulge in the lumbar spine in relation to age. kMRIs in the flexion, neutral, and extension positions were performed on 410 consecutive patients ...
The patients had preoperative cervical spine AP, lateral, flexion and extension radiographs, CT scan and MRI and postoperative radiographs as preoperative views obtained at 1, 3 and 6 months after surgery. Myelopathy severity evaluated preoperative, 3-months and 6-months post...
Fernie GR. Functional biomechanics of the spine - TJ () Citation Context ...tic MRI: kMRI: • Imaging during dynamic-kinetic somatic manoeuvres (flexion, extension, rotation, lateral bending) weighted fast spin echo imaging (T2FSEWI), axial lumbar T1WI (600, 20, 2) or T1FSEWI =-=(...
The method uses higher quality conventional MRI to determine bone geometries and then registers these with lower resolution, positional MRI images of various postures to determine the relative locations of the bones. Flexion/extension, lateral bend, and axial twist rotations were measured for ...

Unilateral and bilateral facet fractures and dislocations of the subaxial spineKeywords MRI magnetic resonance imagingUnilateral and bilateral facet fractures and dislocations can be a challenge to the treating spinal surgeon. Without a high index of suspicion, the diagnosis can be missed or delayed, ...
1 A: Axial T2-weighted MRI image through the L4-L5 disc showing the multifidus (MU), iliocostalis (IL), longissimus (LO), quadratus lumborum (QL), intertransversarii (IT), and psoas (PS) muscles. B: Axial T2-weighted image at the L5 pedicle 鈥...
MRI utilizationINJURYCLASSIFICATIONDISLOCATIONSRULEObjectiveThis study aimed to retrospectively distinguish true- from false-positive fractures of anterior subaxial cervical osteophytes, which were reported on noncontrast computed tomography reports, and to correlate the imaging findings with patient symptoms and...
MRIsubaxial cervical spineStudy design: A retrospective case-control study. Objective: Investigating the correlation between the facet tropism (FT) and subaxial cervical disc herniation (CDH). Summary of background data: Although debatable, it was widely reported that FT was associated with lumbar ...
