Overview
CT-[1]
CT scanning is a valuable, noninvasive procedure for confirming the presence of pulmonary hypertension.
Different types of CT imaging have been used to rule out certain etiologies of pulmonary hypertension and to delineate the anatomy of the pulmonary vasculature:
1-Contrast-enhanced images may show intraluminal abnormalities in the arteries and veins, which are useful for confirming etiologies such as thromboembolic disease.
2-High-resolution CT (HRCT) scanning of the chest has a role in the evaluation of pulmonary hypertension in patients with suspected diffuse lung disease, like in patients with scleroderma, interstitial lung disease, and histiocytosis X.
3- Spiral CT scan in a patient with pulmonary hypertension can also reveal enlarged pulmonary arteries and an absence of thrombosis.
- The upper limit of normal for the diameter of the pulmonary artery is 28.6 mm. A value greater than 28.6 mm suggests increased pressures in the pulmonary system.
