Abstract:
Objective To study the very early diagnosis of acute myocardial infarction (AMI) by harmonic imaging integrated backscatter(IBS).Methods Thirty normal persons,12 cases at the very early stage of AMI (in 2 hours),36 cases with AMI (in 2-12 hours) were examined by IBS and the cyclic variation of integrated backscatter (CVIB) with HP Sonos 5500 ultrasonic system in different areas (the areas of myocardial infarction and no myocardial infarction).Results In the areas of AMI of the very early stage (in 2 hours),IBS was much higher than that of the areas of normal (14.7 vs 8.3,P
