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.
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 ...
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 .
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 ...
chiropractors may X-ray the same patient several times a year, even though there is no clear evidence that X-rays will help the therapist treat the patient. X-rays can reveal neither the subluxations nor the innate intelligence associated with chiropractic philosophy, because they do not exist.
QCT enables spine BMD measurements on patients with scoliosis, which cannot usually be measured using Dual-energy X-ray absorptiometry (DXA). [8] In addition, QCT can avoid the artificially high BMD measurements that can confuse the results from DXA in arthritic patients, patients who are obese , [ 9 ] who suffer from disc space narrowing or ...
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."
The purported displacement is not necessarily visible on static imaging studies, such as X-rays. [8] This is in contrast to the medical definition of spinal subluxation which, according to the WHO, is a "significant structural displacement", and therefore visible on X-rays. [8] As of 2014, the National Board of Chiropractic Examiners states: [15]
