A 64-slice CT with reconstructions does not entirely rule out ligamentous injury leading to instability, but is a practical means of identifying the majority of C-spine injuries in obtunded patients. MR C-spine has frequent false-positives, limiting its usefulness. [citation needed] In these cases, a consultation with a Spine Surgery specialist ...
However, the cervical spine is comparatively mobile, and some component of this movement is due to flexion and extension of the vertebral column itself. This movement between the atlas and occipital bone is often referred to as the "yes joint", owing to its nature of being able to move the head in an up-and-down fashion.
Those with neck pain only without any positive neurological findings usually do not require an x-ray of the cervical spine. For those with chronic neck pain, a cervical spine x-ray may be indicated. There are various ways of doing cervical spine X-rays such as anteroposterior (AP) view, lateral view, Swimmer's view, and oblique view.
The clivus is an important landmark for checking for anatomical atlanto-occipital alignment. When viewed on a lateral C-spine radiograph, the clivus forms a line which, if extended, is known as Wackenheim's clivus line. Wackenheim's clivus line should pass through the dens of the axis or be tangential to it. [9]
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 ...
Radiography is an imaging technique using X-rays, gamma rays, or similar ionizing radiation and non-ionizing radiation to view the internal form of an object.Applications of radiography include medical ("diagnostic" radiography and "therapeutic radiography") and industrial radiography.
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.)
The Hounsfield unit (HU) scale is a linear transformation of the original linear attenuation coefficient measurement into one in which the radiodensity of distilled water at standard pressure and temperature is defined as 0 Hounsfield units (HU), while the radiodensity of air at STP is defined as −1000 HU.
