Normal anatomy
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
Basic screening
- Lung parenchyma: Scan for opacities, preferably at a maximum intensity projection of about 8 mm in order to detect any lung nodules.[1]
- Pleura, for any fluid in the dorsal parts
- Skeleton: Any signs of damage.
- Lymph nodes in mediastinal, hilar and axial areas. If possibly enlarged, see CT of thoracic lymphadenopathy
- Visible abdominal volumes for any expansions or focal changes in the liver, adrenals or spleen.
Report
Even absence of opacities in the lung.
Diseases
- Vascular
- Lymph nodes
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.[2]
