Why is patient positioning important in X rays?

A good positioning technique is of great importance in radiology in order to obtain accurate diagnostic information and reduce the patient’s X-ray exposure.

Should X ray positioning?

The upright position is preferred for the following reasons: It prevents engorgement (an excess of blood) of pulmonary vessels, whereas supine or recumbent positioning tends to increase engorgement of pulmonary vessels, which can change the radiographic appearance of these vessels and the lungs.

What is the difference between projection and position?

For example, a right lateral position indicates that the patient is on his side and that the right side is closest to the X-ray film. Radiographic projection describes where the X-ray beam enters and exits the patient, such as through the front and out the back of the body.

What is Rao in xray?

Position the patient as for chest radiographs (AP, PA, oblique, and lateral). The right anterior oblique (RAO) position is usually used in preference to the left anterior oblique (LAO) position. An RAO position of 35°-40° gives a wider space for an image of the esophagus between the vertebrae and the heart.

What are the various projections used in radiology?

In the US, five or six projections are common; a Lateral, two 45 degree obliques, an AP axial (Cephalad), an AP “Open Mouth” for C1-C2, and Cervicothoracic Lateral (Swimmer’s) to better visualize C7-T1 if necessary.

What is Rao and Lao?

Rotation describes the position of the image intensifier around the longitudinal axis of the patient. LAO refers to rotating the camera to the patient’s left (catheter and spine will be on the right side of the image), RAO to the patient’s right (catheter and spine on the left side of the image).

What is the Lao position?

LAO view — This is obtained with the left front of the patient against the cassette. The patient is turned approximately 45 degrees toward the left side, placing the patient’s left shoulder in contact with the grid device and right hand on their hip. This position demonstrates the maximum area of the right lung field.

What is Proctologic position used for?

The medical profession is authorized to use the proctological positioning that allows the most reliable anal diagnoses.
