Posterior-Anterior
Posterior-anterior (PA) views minimize the magnification of the heart on x-rays.
Study Smarter
Posterior-anterior (PA) views minimize the magnification of the heart on x-rays.
Lordotic view allows evaluation of upper lungs because it “raises” the clavicles out of the way. Therefore the beam is shot diagonally from below the waist towards the shoulders.
Lateral decubitus views (patient lying on the side) are good for evaluating pneumothorax and pleural effusion. This particular film shows a patient on the left side.
In lateral views, the beam traveling from right to left minimizes the magnification of the heart.

Evaluate for Right Ventricle Enlargement
Evidence of an enlarged right ventricle can be as follows:
Evaluate for Right Atrial (RA) Enlargement
Evidence of right atrial enlargement can be as follows:

Evaluate for Pericardial Effusion
Evidence of a pericardial effusion can be as follows:
Evaluate for Left Ventricle (LV) Enlargement
Evidence of an enlarged left ventricle can be as follows:
Measure 1.8 cm posteriorly and then 1.8 cm superiorly. If the cardiac shadow extends beyond this point then LV enlargement is suggested.
Evaluate for Left Atrium Enlargement
Evidence of an enlarged left atrium can be as follows:
