CBCT in Chiropractic

CBCT is a technology that was developed by the dental profession to better image the jaw structure for implants. Before CBCT, 3D analysis was not possible for the small private dental practices. Implants were done with digital 2D technology. Oftentimes implants would not anchor into the bone correctly because the lack of 3D imaging.

CBCT is the new generation of imaging that allows for precision in upper cervical care like never before. We have imaging technology that can precisely detect spinal misalignments that are impacting the central nervous system, and most of the time correct the underlying cause of many chronic health problems.

We are excited about this new technology as it allows the doctor to analyse images that give better detail, resolution, and 3D clarity that simply is not possible with digital x-ray. While digital x-ray is still an amazing tool, CBCT is the new imaging technology for the future.

Cervical spine scans play a crucial role in the evaluation of patients who are experiencing these conditions. Just like many other parts of the body, no two people are alike in the architecture of their spine. This means that each person is unique in their bone structure and mechanics and should be treated according to their needs.

When undertaking a CBCT cervical spine scan, this is normally performed in a seated or standing position which is more representative of the spine’s normal upright orientation. 

The radiation exposure is much less than standard X-Ray series. A standard CBCT scan is 240 micro sieverts, which is equivalent to about 1/10 the radiation exposure of a standard 4-view Cervical spine X-Ray series. This is the equivalent to the exposure of a 5 hour airplane flight.

Since the human structure is 3-dimensional, it is vital to view it with 3D imaging in order to accurately evaluate the alignment. Traditional X-ray is 2-dimensional, so certain factors like anatomical variations, positioning errors, and asymmetry of structures can result in misdiagnosis some of the time. Until now, traditional X-Ray, while flawed, was simply the best form of imaging we had available for the spine. CBCT imaging has changed that. The detail of bony anatomy provided by a CBCT image of the cranio-cervical junction (CCJ) is useful to appreciate the components of the CCJ and its role in cervical spine stability and clinical implications. The cranio-cervical junction is an area of unique consideration given bone morphology, biomechanics, ligamentous structures, fluid dynamics, neurology, and neurophysiologic effects attributed to that area. Additionally, CBCT may be indicated to evaluate for traumatic fractures and hairline fractures within the cervical spine. It may also be used to evaluate cervical spine spondylosis, intervertebral foraminal stenosis, and facet joint arthrosis. These abnormal findings are regularly evaluated for in chiropractic offices that specialise in the cranio-cervical junction.
