What is the best position for a chest film?

What is the best position for a chest film?

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.

Why do we do chest ap?

Indications. The erect anteroposterior chest view is an alternative to the PA view when the patient is too unwell to tolerate standing or leaving the bed 1. The AP view examines the lungs, bony thoracic cavity, mediastinum, and great vessels.

Why do AP Xrays show chest?

The heart, being an anterior structure within the chest, is magnified by an AP view. Magnification is exaggerated further by the shorter distance between the X-ray source and the patient, often required when acquiring an AP image. This leads to a more divergent beam to cover the same anatomical field.

What is a PA view of the chest?

The posteroanterior (PA) chest view examines the lungs, bony thoracic cavity, mediastinum and great vessels.

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.

What is a Lordotic position?

Lordosis is defined as an excessive inward curve of the spine. It differs from the spine’s normal curves at the cervical, thoracic, and lumbar regions, which are, to a degree, either kyphotic (near the neck) or lordotic (closer to the low back).

What is the oblique projection position in chest chest PA?

Chest PA Oblique Projection Purpose and Structures Shown A right anterior oblique position for a slightly oblique projection of the sternum. If this position is difficult in trauma patients, upright positioning may be necessary or the patient may be positioned supine and the left anterior oblique position used with AP oblique projection.

What are the recommended viewing positions for a pulmonary artery projection?

Right and left oblique and lateral view are also requested by their physician as required for supplemental studies for the PA projection. Upright position is necessary as possible is patient can tolerate, because in this position it prevents the maximum expansion of the lungs.

What is the correct position for a chest xray?

Upright position is necessary as possible is patient can tolerate, because in this position it prevents the maximum expansion of the lungs. On erect position, it best demonstrates pleural effusions, pneumothorax and atelectasis and other sign of infections are also evident if present.

What is the AP view on a chest X-ray?

The reason is that the patient’s chest (anterior) is against the x-ray film with the beam entering from posterior (P) to anterior (A) – hence the term “PA.” Similarly, the AP view is when the beam enters from front to back with the x-ray film at the back of the patient – therefore, the heart is magnified and the margins are minimally less sharp.
