A first step toward automatic assessment of lumbar spine MRI is segmentation of relevant anatomical structures, such as the vertebrae, intervertebral discs (IVDs) and the spinal canal. With recent advances in machine learning and artificial intelligence (AI), state-of-the-art spine segmentation ...
I have had two spinal cord stimulators as the pain would always return. The Neurosurgeons classified me as a “failed back surgery syndrome” patient. As before I would study my images and identify where the electrodes were placed. Only this time I had all my images loaded on my iPad ...

The precise dimensions of the lumbar vertebrae and discs are critical for the production of appropriate spinal implants. Unfortunately, existing databases of vertebral and intervertebral dimensions are limited either in accuracy, study population or parameters recorded. The objective of this study is to ...
In the next step, a third-order polynomial is aligned on the extracted spinal cords, and in the end of preprocessing step all the T2-W sagittal images are prepared for extracting disc boundary and labeling. After labeling and extracting a ROI for each disc, intensity and shape features are ...
