Despite the increasing number of modern diagnostic imaging techniques accessible to clinicians, chest roentgenography remains a straightforward, low-cost, and highly insightful examination. A roentgenogram, also known as an x-ray image is a photograph of internal structures made by moving x-rays through the body and forming a shadow image on specially sensitized film. Roentgenography was named after Wilhelm Conrad Röntgen, a German physicist who invented it in 1895. The chest x-ray is a reliable method for predicting pulmonary hemodynamic events in patients without chronic obstructive pulmonary disease and offers a fair estimation of pulmonary venous and arterial pressures. Unfortunately, the pulmonary vascular distribution of patients with chronic obstructive pulmonary disease may be substantially altered. This complicates roentgenographic assessment.
