Normal anatomy

High-resolution computed tomographs of a normal thorax, taken in the axial, coronal and sagittal planes, respectively.

Angiography

CT angiography of the thorax is a contrast CT exam, tailored to the proper contrast phase depending on the level of the suspected condition by the referring clinician:

  • Veins from contrast infusion
  • Pulmonary veins

Diseases

Lymphadenopathy

Definition by size
Mediastinum, generally 10 mm[1][2]
Superior mediastinum and high paratracheal 7mm[3]
Low paratracheal and subcarinal 11 mm[3]

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.[4]
