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.
The radiation doses received from CT scans is variable. 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 ...
In some, the x-ray findings may correspond to symptoms of back stiffness with flexion/extension or with mild back pain. [2] Back pain or stiffness may be worse in the morning. [4] Rarely, large anterior cervical spine osteophytes may affect the esophagus or the larynx and cause pain, difficulty swallowing [5] [6] or even dyspnea. [7]
A very early paper published in 1898, presented anatomic variations to have a wide range and significance, [3] and before the use of X-ray technology, anatomic variations were mostly only found on cadaver studies. The use of imaging techniques have defined many such variations. [4]

Quantitative computed tomography (QCT) is a medical technique that measures bone mineral density (BMD) using a standard X-ray computed tomography (CT) scanner with a calibration standard to convert Hounsfield units (HU) of the CT image to bone mineral density values. [1]
