Can pulmonary hypertension be diagnosed without a ct scan?

Yes: Pulmonary hypertension can be diagnosed with echocardiography or heart catheterization as well. Each method supplies different types of additional information.

Yes: Usually, pulmonary hypertension is screened with an echocardiogram. Once this is abnormal, many tests are done including a right cardiac catheterization to make the diagnosis. A ct scan may be needed to look at the lung tissue and see if there is damage to the lung that can explain why someone has pulmonary hypertension.

CT scan: The conclusive diagnostic test for pah is a right heart catheterization to measure pulmonary artery pressures and cardiac output. The diagnosis may be supported by physical findings, blood tests, chest x-rays, electrocardiograms, echocardiograms, pulmonary function tests, exercise tolerance tests (six-minute walk tests) and nuclear scans (ventilation/perfusion scan), but these tests may be negativ.
