===Pulmonary hypertension===
The presence of a dilated main pulmonary artery of 29 mm or more in combination with an artery–to-bronchus diameter ratio of 1:1 or more at segmental level in three or four lobes, confers a specificity of 100% for the presence of pulmonary hypertension.<ref name="PeñaDennie2012">{{cite journal|last1=Peña|first1=Elena|last2=Dennie|first2=Carole|last3=Veinot|first3=John|last4=Muñiz|first4=Susana Hernández|title=Pulmonary Hypertension: How the Radiologist Can Help|journal=RadioGraphics|volume=32|issue=1|year=2012|pages=9–32|issn=0271-5333|doi=10.1148/rg.321105232}}</ref>
