What is the increase in lung markings disorder?

Double lung markings disorder is an imaging term that refers to an increased disorder of bronchial vascular bundles in both lungs on chest radiographs or chest ct scans. This condition is clinically common in bronchitis. It can also be seen in other conditions, such as chronic pulmonary congestion caused by cardiac insufficiency. Even sometimes pneumonia, bronchiectasis and other related diseases can show increased disorder of bilateral lung markings on chest radiograph, but after chest ct examination, it is often diagnosed.
