SPINE Flashcards
What is the name of the soft, inner layer of the intervertebral disks?
Nucleus pulposus
The toothlike projection from the superior surface of the body of the axis is called the
Dens or odontoid process
What is the proper CR angle and direction for the AP oblique projection of the cervical spine?
15 degrees cephalad
If the base of the skull is superimposing the dens in the open mouth technique, what positioning error has occurred?
The patients neck was extended too much
The patient is positioned with the coronal plane of the body perpendicular to the IR, the MSP is parallel to the IR, and the arm closest to the IR is raised over the head. The CR is perpendicular and centered to C7-T1 interspace. What anatomy and projection are demonstrated on this image?
A lateral projection of the cervicothoracic spine
Which of the following must be done to demonstrate the cervical intervertebral foramina in the patients right side?
CR 15 degrees caudad,patient in the RAO
The RAO position of the cervical vertebrae demonstrates which side of the patients intervertebral foramina
Right
What is the proper patient position for an AP oblique projection of the cervical spine?
45 degrees posterior oblique position
Which vertebrae is known as the axis?
C2
The vertebral arch is formed by the
Pedicles and laminae
What is one of the unique anatomic characteristics of the cervical vertebrae
Cervical vertebrae have a transverse foramen on each side of the body
Where should the CR enter the patient for a lateral projection of the cervicothoracic spine?
Perpendicular through C7-T1 interspace
What anatomic structures of the cervical spine are best demonstrated by the lateral projection?
Zygapophyseal joints
Which vertebrae should be included in the lateral projection of the cervicothoracic spine?
C6-T3
Which of the following body positions demonstrates the left zygapophyseal joints of the lumbar spine?
45 degrees LPO
