| Popis: |
The authors developed a method of evaluation of the right ventricular (RV) ejection fraction based on the use of the left oblique projection for visualization of the right ventricle, separation of the RV contour into the systole and diastole, and subtraction of the surrounding tissue background calculated by a distance-dependent method. The proposed algorithm was shown to be versatile in evaluation of the background for RV and LV investigations. The results of determination of the RV ejection fraction in patients with chronic pulmonary hypertension of III-IV degree were suggestive of a significant decrease in RV contractility of these patients as compared to controls. |
