Chest X-Ray

Findings

Is heart enlarged or normal?

Signs of heart failure and fluid overload?

Does patient have pneumonia or collapsed lung?

Is there evidence of emphysema?

Are there findings of an aortic aneurysm?

Is there fluid in the sac that surrounds the lung?

Is there free air under the diaphragm?

Is there a tumor in the lung that could represent cancer?

NORMAL CHEST X-RAY

PA LATERAL

Two (2) projections are needed for most x-rays to locate structures in 3 planes (1)Right or Left , (2) Anterior or Posterior) or (3) Superior or Inferior.

CONGESTIVE HEART FAILURE

55

Evolution of congestive heart failure and pulmonary edema. With Progressive Lt. Ventricular failure blood backs into the left atrium—then to the pulmonary veins (PULMONARY VENOUS HYPERTENSION) then to the pulmonary interstitium (INTERSTITIAL EDEMA) then to the alveoli (ALVEOLAR EDEMA)

Rib fracture on the left are associated with a small pleural effusion blunting the costophrenic angle. Compare with normal RT. side.

Coin in esophagus shows a wider diameter than possible in the trachea and is posterior to the tracheal air stripe on the lateral chest x-ray.
