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 ...

This paper proposes a fully automated approach to segment the spinal cord using clinical 2D axial-view MRI slices from CSM patients. The proposed method introduces CNN to provide initialization for the improved level set-based method. The level set-based method introduces a grayscale regularizer to...
Thirty-two axial images of the cervical spinal cord were acquired using a General Electric 1.5 T Signa Excite MR Scanner equipped with the eight-channel cervical–thoracic–lumbar spine array coil, and a two-dimensional fast relaxation fast spin echo sequence (slice thickness = 3 mm, ...
I work on GE excite open speed. On lumbar spine t2axials, it appears like the coil looses signal and makes image dark and grainy. The coil gives good signal on the other sequences and tests good when engineer has tested it. The sag t2 is bright like it should but ax is dark. Any...
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 ...

It can view slices from the bottom (axial), front (coronal), or sides (sagittal), depending on what your doctor needs to see.A dye (contrast agent) may be injected into your bloodstream to enhance certain tissues. The dye contains gadolinium, which has magnetic properties. It circulates ...

Dynamic contrast-enhanced (DCE) MRI provides physiologic, functional information about tumor vascularity and hemodynamics. Applied to the osseous spine, this technique can in some cases distinguish hypervascular lesions from inflammatory processes, degenerative changes, post-treatment marrow alterations, and ...
