In order to prevent further injury, such people may have a collar placed by medical professionals until X-rays can be taken to determine if a cervical spine fracture exists. [5] Medical professionals will often use the NEXUS criteria and/or the Canadian C-spine rules to clear a cervical collar and determine the need for imaging.
EOS is a medical imaging system designed to provide frontal and lateral radiography images, while limiting the X-ray dose absorbed by the patient in a sitting or standing position. The system relies on the high sensitivity of a detector ( multi-wire chamber ) invented by Georges Charpak , which earned him the 1992 Nobel Prize .
On lateral C-spine X-ray, the thumbprint sign describes a swollen, enlarged epiglottis. [10] A normal X-ray, however, does not exclude the diagnosis. [10] An ultrasound may be helpful if specific changes are present, but its use (as of 2018) is in the early stages of study. [10] On CT imaging, the "Halloween sign" describes an epiglottis of ...
Myelography is a type of radiographic examination that uses a contrast medium (e.g. iodised oil [1]) to detect pathology of the spinal cord, including the location of a spinal cord injury, cysts, and tumors. Historically the procedure involved the injection of a radiocontrast agent into the cervical or lumbar spine, followed by several X-ray ...
Position of C7 shown in red. The vertebra prominens , or C7, has a distinctive long and prominent spinous process, which is palpable from the skin surface. Sometimes, the seventh cervical vertebra is associated with an abnormal extra rib, known as a cervical rib , which develops from the anterior root of the transverse process.
The images may also be used to check for other requirements of some types of treatment, such as full or empty bladder, empty rectum, etc. [8] [27] The same cone beam beam source and detector can alternatively be used to take simple X-ray positioning images if the organ shows particularly well on X-ray or if Fiducial markers have been inserted ...

1. Cervical spine x-ray (lateral view) Once there is an onset of the symptoms in the patient, the patients are screened through cervical-spinal imaging techniques: X-ray, CT, MRI. The scanning technique points out any cervical vertebrae defects and misalignments. (Image 1. and 2.)
