[Patterns of pulmonary vascularization on plain-film chest X-rays]. / Los patrones de vascularización pulmonar en la radiografía simple de tórax.

ABSTRACT

Plain chest films are a fundamental tool in the practice of medicine. The apparent simplicity of plain chest films sometimes leads us to forget that interpreting them correctly can provide very valuable information, especially if the interpretation is grounded in key clinical information. To interpret a plain chest film, it is important to pay attention to the pulmonary vascularization. This article reviews the normal shape and distribution of the pulmonary vessels on plain chest films and the most common pathologic vascular patterns, including those seen in pulmonary hypertension, hyperemia, hypovascularization, and alternative perfusion.
