A problem in quantitative two‐dimensional echocardiography is myocardial dropout of still frame images. This study was designed to evaluate the ability of digital averaging to overcome myocardial dropout without distorting quantitative measurements. Forty‐one percent of 80 digitally averaged images were thought to be improved by five independent observers, whereas 78 showed some deterioration. Measurements obtained from processed images were statistically identical (r ≥ 0.9) to those from three arithmetically averaged, unprocessed images in 60 patients. Digital averaging can improve image quality without measurement distortion and should facilitate two‐dimensional echocardiographic quantitation.
