Abstract:
On a left lateral chest radiogram,3 points are determined:A is the apex of the sternal angle formed by the manubrium and the body of the sternum,B is the highest point of the contact surface between the anterio-superior heart border and the anterior chest wall,and C is the apex of the anterior costophrenic angle.The distances of AC and BC are measured.The ratio of BC:AC is considered as an index of the size of the right ventricle.On the basis of measuring 120 normal subjects,0.54(0.46?0.04) is employed as the upper limit of normal values.Left lateral chest radiogram is easy to take.The measuring procedure is simple.The results of this measurement proves to be valuable after the method has been applied clinically.In the evaluation of the size of the right ventricle,this new digital index is helpful in the analysis of serial radiograms.This measurement makes left lateral chest radiogram more useful in detecting cardiac abnormalities.
