Cervical Spine Case Study
Diagnostic Imaging Techniques
After going through medical and physical examinations, doctor requested X-ray to be done to ensure that diagnosis was correct and source of pain. Two projections was ordered. There are Antero-posterior projection and Lateral projection of the Cervical spine.

Rationale for choice of factors
Two projections was done so that better view of the cervical spine can be seen. Choice for kVp and mAs for both projections was used to sufficiently penetrate to be able to see the soft tissue and bony trabeculations. High kVp was …show more content…
For Antero-posterior (AP) Projection of Cervical Spine
§ The areas from superior portion of C3 to T12 should be visible on the radiographic image.
§ There should be a superimposition of the shadows of the mandible and occipital over the atlas and most of the axis seen on the radiographic image showing that the patient extend the chin enough to be able to see fully the cervical vertebrae well.
§ The cervical spine was not seen rotated on the radiographic image as the spinous processes were equidistant to the pedicles and were aligned with the midline of the cervical vertebrae.
§ The equidistant of the mandibular angles and mastoid processes to the vertebrae as shown on the radiographic image also indicated that the neck was over rotated or under rotated, but parallel to the erect bucky.
For Lateral Projection of the Cervical Spine
§ On the radiographic image, all of the seven cervical vertebrae and T1 were clearly shown indicating sufficient depression of the shoulder.
§ The mandibular rami were not superimposing the atlas or axis as seen on the radiographic image showing that the neck
