Calculation of pulmonary distensibility with ECG-gated CT for the diagnosis of pulmonary hypertension

A recent study compared ECG-gated CT, ungated CT and echocardiography for the assessment of pulmonary hypertension due to left heart disease. Pulmonary distensibility, as assessed on ECG-gated CT, has an area under the receiver operating characteristic curve of 0.92 in detecting pulmonary hypertension, with a better performance in comparison to the other two imaging techniques.
