What are two important benefits of an SID longer than 40-44 inches for the lateral cervical spine projections?
Less divergence of x-ray beam to reduce shoulder superimposition of C7, and compensates for increased OID; reducing magnification.
What is the name of the radiographic procedure that requires the injection of contrast media into the subarachnoid space?
Myelography
In addition to extending the chin, which additional positioning technique can be performed to ensure that the mandible is not superimposed over the upper cervical vertebrae for the oblique projections?
Rotate the skull into a near lateral position.
Which foramina are demonstrated witha a left anterior oblique (LAO) position of the cervical spine?
The left intervertebral foramina or downside.
Where should the central ray be placed for a cervicothoracic (swimmer's lateral) projection?
At T1 1 inch above jugular notch, or at the vertebral prominence (C7)
In addition to the gonads, which 3 other radiosensitive organs are of greatest concern during cervical and thoracic spine radiography
Thyroid gland, para thyroid glands, and female breasts.
