What is the AP spine?
The anteroposterior (AP) cervical spine projection is part of the cervical spine series.
What is the reference point for the lateral projection of the thoracic spine?
The entire thoracic spine should be visible from T1 to T12: intervertebral joints and neural foramen are open, with the superimposition of the posterior spinous processes and posterior rib articulation indicating a true lateral has been achieved.
What is lumbosacral spine AP LAT?
A lumbosacral spine X-ray, or lumbar spine X-ray, is an imaging test that helps your doctor view the anatomy of your lower back. The lumbar spine is made up of five vertebral bones. The sacrum is the bony “shield” at the back of your pelvis. It’s located below the lumbar spine.
What vertebrae do you need to include in an AP thoracic spine projection?
The entire thoracic spine should be visible from T1 to T12: no patient rotation as evident by central spinous processes with sternoclavicular joints appearing equidistant.
What is an AP axial?
The AP lordotic chest radiograph (or AP axial chest radiograph) demonstrates areas of the lung apices that appear obscured on the PA/AP chest radiographic views.
How much should an AP c spine angle be?
B: For the AP view of the cervical spine, the patient is either erect or recumbent. The beam is directed toward the C-4 vertebra (at the Adam’s apple) at an angle of 15°-20° cephalad.
Which of the following are demonstrated in the lateral projection of the thoracic spine?
Which of the following is (are) demonstrated in the lateral projection of the thoracic spine? The correct answer is (C). The thoracic intervertebral (disk) spaces are demonstrated in the AP and lateral projections, although they are probably best demonstrated in the lateral projection.
What does AP mean in radiology?
anteroposterior
AP, X-ray: An X-ray picture in which the beams pass from front-to-back (anteroposterior). As opposed to a PA (posteroanterior) film in which the rays pass through the body from back-to-front.
What is an advantage of taking a lumbar spine PA instead of AP?
The DAP reduction of approximately 27% and effective dose reduction of approximately 53% is achievable by using the PA instead of a standard AP projection in lumbar spine radiography.
What is the central ray angle for an AP thoracic spine?
When the shoulder is immobile and cannot be depressed sufficiently for the cervicothoracic region lateral projection (swimmer’s technique), the central ray is angled: 0 degrees. What is the central-ray angle for an AP thoracic spine? 20 degrees.
