摘要: The renal arteries of 62 children and adolescents aged 1-16 years without or renovascular disease were examined by computer Doppler duplex sonography (DDS) to measure absolute blood flow velocities. Maximum systolic velocity (Vmax) time average (TAV) not age-dependent. In addition, values artery measured. Renal was 4.1 +/- 1.2 ml/min per gram kidney (two standard deviations), independent age comparable commonly accepted physiological values. coefficient variation calculations 6%-15% depending on vessel diameter.
