The upper cervical spine has a curve, convex forward, that begins at the axis (second cervical vertebra) at the apex of the odontoid process or dens and ends at the middle of the second thoracic vertebra; it is the least marked of all the curves. This inward curve is known as a lordotic curve. A thoracic spine X-ray of a 57-year-old male.
X-ray, MRI, CT Scan Lordosis is historically defined as an abnormal inward curvature of the lumbar spine . [ 1 ] [ 2 ] However, the terms lordosis and lordotic are also used to refer to the normal inward curvature of the lumbar and cervical regions of the human spine .
Compared to the lowest dose X-ray techniques, CT scans can have 100 to 1,000 times higher dose than conventional X-rays. [149] However, a lumbar spine X-ray has a similar dose as a head CT. [ 150 ] Articles in the media often exaggerate the relative dose of CT by comparing the lowest-dose X-ray techniques (chest X-ray) with the highest-dose CT ...
Lead is the most common shield against X-rays because of its high density (11,340 kg/m 3), stopping power, ease of installation and low cost. The maximum range of a high-energy photon such as an X-ray in matter is infinite; at every point in the matter traversed by the photon, there is a probability of interaction.
The vertebral column, also known as the spinal column, spine or backbone, is the core part of the axial skeleton in vertebrate animals.The vertebral column is the defining and eponymous characteristic of the vertebrate endoskeleton, where the notochord (an elastic collagen-wrapped glycoprotein rod) found in all chordates has been replaced by a segmented series of mineralized irregular bones ...
X-ray motion analysis is a technique used to track the movement of objects using X-rays. This is done by placing the subject to be imaged in the center of the X-ray beam and recording the motion using an image intensifier and a high-speed camera , allowing for high quality videos sampled many times per second.
The use of X-ray imaging in the case of vertebral subluxation exposes patients to harmful ionizing radiation for no evidentially supported reason. [ 54 ] [ 55 ] The 2008 book Trick or Treatment states "X-rays can reveal neither the subluxations nor the innate intelligence associated with chiropractic philosophy, because they do not exist."
It uses specific manual thrusts focused on restoring normal biomechanical function. It has been developed to adjust extremity joints, as well. Gonstead Technique—Developed by an automotive engineer-turned-chiropractor, this technique uses a precise analysis method, including stereoscopes, full spine X-rays, and precise adjusting techniques ...
