Fig. 4From: A decision tree built with parameters obtained by computed tomographic pulmonary angiography is useful for predicting adverse outcomes in non-high-risk acute pulmonary embolism patientsCardiac volume measurement. a. The heart chambers were differentiated as RV (right ventricle), LV (left ventricle), RA (right atrium) and LA (left atrium). b. Every heart chamber was reconstructed, the volume parameters were measured, and the relative ratios were calculatedBack to article page
