Answer

A study of multidetector computed tomography (MDCTA) for detection of right ventricular dysfunction in 457 patients with acute pulmonary embolism found reasonable correlation with echocardiography, the reference standard. The criterion selected, a right-to-left ventricular dimensional ratio of 0.9 or more at MDCTA, had 92% sensitivity for right ventricular dysfunction. [73] The combination of quantitative assessment of ventricular dimensions by CT and measurement of biomarkers may provide additional diagnostic accuracy for the presence of right ventricular dysfunction.
