A new radiographic technique produces a high quality image of the chest at end systole and end diastole in a single radiograph. A preliminary study of this method for evaluating various degrees of segmental asynergy of the left ventricular free wall in 25 patients with coronary artery disease showed excellent correlation with left ventriculography (r = 0.88). The method showed a high sensitivity (94%) and specificity (96%). It seems potentially useful to increase the information gained from the chest radiograph in patients with cardiac disease.
