[Changes in the pattern of pulmonary vessels shown on x-ray film (author's transl].
The pattern of the pulmonary vessels seen on plain film of the thorax depends on the perfusion of the lungs which depends on the respiratory condition, position in which the x-ray film is taken, and various pathological processes. Pathological findings become evident as localised or generalised increase or decrease in the marking of the vessels, sharpness of outline and pattern of distribution being further assessment criteria. Early analysis of these changes is an important diagnostic step to identify the beginning of pulmonary-venous or pulmonary-arterial pressure increase.
