MULTISLICE COMPUTED TOMOGRAPHY EVALUATION OF PULMONARY HYPERTENSION SECONDARY TO LUNG DISEASES

Aim: to evaluate the role of multislice computed tomography in diagnosis of pulmonary hypertension secondary to lung diseases.
Patients and Methods: This study was done during the period from March 2014 to August 2014. Patients were subjected to radiological examinations including plain X-ray, echocardiography and multislice computed tomography (MSCT)
Results: 30 patients 18 male and 12 female with age ranged from 30 to 72 years. The size of the main pulmonary artery (PA) was the first radiological sign to be assessed. The main PA diameter to be measured at point of bifurcation at right angle to its long axis and just lateral to the ascending aorta. Among our 30 cases, 27 patients have a ratio between the main pulmonary artery size and the ascending aorta size (PA / AO ratio) more than (1: 1).
Conclusion: MSCT has a main role in evaluation of pulmonary hypertension secondary to lung diseases.
