Table 1 Ultrasonic Screening and diagnosis of 140 cases with aortic arch abnormalities in each view and four-view combination

From: Study on the views and methods of ultrasonic screening and diagnosis for abnormal aortic arch in infants

Classification Number of cases the three-vessel and tracheal view the aortic arch short axis view the left aortic arch long axis view the aortic arch long axis continuous scan views four-view combination
