Now, I consider that the phrenologists have omitted an important thing in not pushing their investigations from the cerebellum through the spinal canal. For I believe that much of a man's character will be found betokened in his backbone.
Although some adjustments were needed, our algorithm was able to find all spinal cords automatically, whose areas account for only 4% of all pixels in images having complete cervical spinal canals. Similar double threshold-based method was employed in other studies, but cropping regions of interest from the original images was needed before determining the threshold automatically [22].
Residing within the spinal canal formed by the spinal vertebrae, the spinal cord is prone to external compression caused by degeneration, trauma, and so forth.
In the literature, there were only a few atlas-free segmentation methods for the human spinal canal or spinal cord [9, 10].
Our method is able to find the spinal cord in images from patients without disruption of the spinal canal. We applied this method to a large number of consecutive patients undergoing a noncontrast MRI study over a 3-month period.
For sagittal T2 sequence, 3 mm sagittal slices with 0.33 mm gaps between them were planned over the coronal image to cover the whole spinal canal [11].
Computed tomography (CT) images were either collected from 80 clinical patients with complaints of lumbago or obtained from 40 sets of lumbar specimens after rebuild of spinal canals. In the CT image processing the heights of the spinous process and laminae at L3-L5 were measured.
[sup][12],[13] This may induce the stenosis of the spinal canal again.
[sup][17],[18] In addition, the enlargement of the central spinal canal is limited.
Its advantage is that it decompresses the nerve roots by expanding the cross-sectional area of the spinal canal without compromising the spinal stability.
