(McCulloch and Transfeldt, 1997). In fact, the intervertebral disc and the pair of facets behind it have been labeled “the three-joint complex” (Kirkaldy-Willis et al., 1978). Thepedicleis directed postero laterally from the body and forms a part of the posterior arch ensconcing the ...
There are three main functions of the lumbar spine. First, the lumbar spine assists in supporting the upper body. The lumbar vertebrae (L1-L5) are much larger compared to other regions of the vertebral column, allowing them to absorb axial forces delivered from the head, neck, and trunk. ...
Non-contrast magnetic resonance imaging (MRI) of the lumbosacral spine is the modality of choice for LSS. This imaging technique has better soft tissue resolution than CT and thus is more sensitive in detecting spinal nerve lesions. Still, CT myelography is an option when MRI is contraindicated,...
A retrospective study was conducted at four hospitals around China, in which the study population composed of patients who completed lumbar-spine MRI examination between January 1, 2019 and March 30, 2021. Further screening was conducted to exclude IVD herniation, lumbar spondylolisthesis, spine tumors...
The data can be used as a training and test datasets for the development of automatic lumbar muscle and spine segmentation algorithms. These algorithms are highly needed to promote and accelerate the wide spread clinical implementation of quantitative muscle MRI for diagnosis of muscle and vertebral ...
(2) Prior spine surgery (3) Patients lost to follow-up. The patients were followed up on the 1st, 3rd, 6th, 12th, and 24th months following surgery. The patients were screened using the visual analog scale score, Oswestry disability index scores, and radiographs were obtained at each ...
After MRI imaging, spinal cords were dissected from the spine and a transverse (1.5-mm-thick) spinal cord block cut from the injury epicenter and prepared for plastic embedding as previously described [41]. Briefly, dissected tissue blocks were treated with 0.1% osmium tetroxide in 0.1 M non-...
from May to December 2015. Sixty sciatic pain patients with LDH as confirmed by MRI will be recruited from outpatients visiting Jaseng Hospital of Korean medicine, which is a spine-specialty hospital designated as such by the Korean Ministry of Health and Welfare (900,000 outpatient cases per ye...
All data were labeled by two spine surgeons using the widely accepted grading system for lumbar spinal stenosis. The training and validation sets were used to annotate the regions of interest by the two spine surgeons. First, a region of interest detection model and a convolutional neural network...
This study aimed to develop an MRI鈥恇ased decision support system for LDH, which evaluates lumbar discs in a reproducible, consistent, and reliable manner. Methods: The research team proposed a system based on machine learning that was trained and tested by a large, manually labeled...
