What is a Rao position?
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 does Rao mean in radiology?

What is RAO projection?

Why we would do anterior obliques or posterior obliques on a rib exam?
Conducting AP rib oblique views produces less magnification of the ribs, and provides more bony detail than that of the PA view 1. When a patient is unable to stand for an erect projection, have the patient supine and supported by immobilization devices to adjust the patient into an oblique position.
What is a PA view?
In a posteroanterior (PA) view, the x-ray source is positioned so that the x-ray beam enters through the posterior (back) aspect of the chest and exits out of the anterior (front) aspect, where the beam is detected. To obtain this view, the patient stands facing a flat surface behind which is an x-ray detector.
What is the right anterior oblique position (Rao)?
Please try again later. The Right Anterior Oblique Position or “RAO” is often used during an Upper Gastrointenstinal Flouroscopy study (UGI or “barium swallow”) to better visualize the esophagus. In this position, the esophagus may be visualized without overlap from the cardiac shadow.
What is the Lao and Rao position in a chest X-ray?
Patient erect, rotated 45degrees with left anterior shoulder against IR for the LAO and 45degrees with right anterior shoulder against IR for the RAO (see note below for 60degrees LAO) Opposite arm raised to clear lung field and hand rested on head or on chest unit for support, keeping arm raised as high as possible
How do you rotate a patient with a 60 degree Lao?
Patient Positions: Patient erect, rotated 45degrees with left anterior shoulder against IR for the LAO and 45degrees with right anterior shoulder against IR for the RAO (see note below for 60degrees LAO) Patient’s arm flexed nearest IR and hand placed on hip, palm out.
