In this paper, we present a method for automatic labeling of the lumbar spine disc pixels in axial view MRI using pixels locations and gray level as features. Clinical MRIs are used for the training and testing of the method. The pixel classification accuracy and the quality of the ...
MRI Lumbar spineDegenerative spine pathologiesThe aim of the study was to assess the Radiological changes occurring after axial loading of the lumbar spine during MRI in patients whose conventional MRI did not explain their clinical symptoms and to evaluate the impact of these changes on the ...

Thecervical, thoracic andlumbar spine MRIshould be scanned in individual sections. The scan protocol parameter like e.g. thefield of view(FOV),slice thicknessandmatrixare usually different forcervical, thoracic andlumbarspine MRI, but the method is similar. The standard views in the basic spinal...
A larger field of view, axial MRI studies covering the complete lumbar spine or additional imaging are required to accurately determine the anatomical labels20. These were not available for the majority of studies in this dataset. The use of traditional clinical nomenclature was therefore considered ...
loading and positions on lumbar structure and lumbar spinal stenosis.#A total of 40 patients sequentially underwent 4 examinations: (1) the psoas-relaxed position MRI, (2) the extended position MRI, (3) the psoas-relaxed position axial loading MRI, (4) the extended position axial loading MRI...

The MRI scan gives two views of the spine, the sagittal view and the axial view. The views are shown in multiple slices and the sagittal and axial views can be correlated on the computer. Anatomy of the Lumbar SpineThe spinal cord really ends at the lumbar 1 vertebrae. Beyond that, the...
