Pulmonary hypertension: The contribution of MDCT to the diagnosis of its different types

Assessment of Right Ventricular Function in Pulmonary Hypertension with Multimodality Imaging

“…Parenchymal lung findings with chronic obstructive pulmonary disease and interstitial lung disease that may be idiopathic or secondary to connective tissue disease or sarcoidosis are observed in patients of Group 3. Pulmonary nodules, extracardiac shunts, and bronchial, and vascular abnormalities can also readily be seen by CT 54)…”

Multislice Computed Tomography Evaluation of Pulmonary Hypertension Secondary to Lung Diseases

“…Pulmonary hypertension is characterized by progressive involvement of the pulmonary vessels that leads to increased vascular resistance and consequently to right ventricular failure (2).…”

“…In cases of suspected pulmonary hypertension, imaging methods can confirm the diagnosis, suggest a cause, help choose the most appropriate treatment, and monitor the response to treatment (2).…”

“…The ain PA diameter to be measured at point of bifurcation at right angle to its long axis and just lateral to the ascending aorta , it is preferable to compare the main PA diameter and the ascending aorta and calculate the ratio between them PA/ Ao ratio (2) An enlargement of the main pulmonary artery greater than 29 mm may be seen on the CT scan . This finding has a sensitivity of 87% and a specificity of 89% for the diagnosis of PH.…”
