Positioning for a PA chest x-ray Normal lateral chest radiograph. Different views (also known as projections) of the chest can be obtained by changing the relative orientation of the body and the direction of the x-ray beam. The most common views are posteroanterior, anteroposterior, and lateral. In a posteroanterior (PA) view, the x-ray source ...

These cannot be determined by plain films, as the x-ray passes through the soft tissue. A study by Giles et al., stated that sixteen of the thirty patients (53%) had retrolisthesis of L5 on S1 ranging from 2–9 mm; these patients had either intervertebral disc bulging or protrusion on CT examination ranging from 3–7 mm into the spinal canal.
Tissues commonly imaged include the lungs and heart shadow in a chest X-ray, the air pattern of the bowel in abdominal X-rays, the soft tissues of the neck, the orbits by a skull X-ray before an MRI to check for radiopaque foreign bodies (especially metal), and of course the soft tissue shadows in X-rays of bony injuries are looked at by the ...
An x-ray beam is angled at 45° to the orbitomeatal line. The rays pass from behind the head and are perpendicular to the radiographic plate. Another variation of the waters places the orbitomeatal line at a 37° angle to the image receptor. It is named after the American radiologist Charles Alexander Waters.
The American College of Radiology recommends that projectional radiography is the most appropriate initial study in all patients with chronic neck pain. [13] Two additional diagnostic tests that may be of use are magnetic resonance imaging and electrodiagnostic testing.
Schuller's view is a lateral radiographic view of skull principally used for viewing mastoid cells. [1] The central beam of X-rays passes from one side of the head and is at an angle of 25° caudad to the radiographic plate. This angulation prevents overlap of images of the two mastoid bones. The radiograph for each mastoid is taken separately.
The parapharyngeal space (also termed the lateral pharyngeal space), is a potential space in the head and the neck. It has clinical importance in otolaryngology due to parapharyngeal space tumours and parapharyngeal abscess developing in this area. It is also a key anatomic landmark for localizing disease processes in the surrounding spaces of ...
