Most people are familiar with common x-ray procedures for chest radiography.
Approximately half of all radiographs obtained in medical institutions are images of the chest. A chest x-ray is usually done for the evaluation of lungs, heart and surrounding anatomy. Pneumonia, heart failure, pleurisy and lung cancer can be diagnosed or suspected on a chest x-ray , along with other less common conditions. Traditionally, chest x-rays have been taken prior to employment, prior to surgery or during immigration. This procedure requires no special preparation.
