Non-invasive ultrasonic imaging of the peripheral arterial system was performed by B-mode scanning and pulsed Doppler ultrasonic arteriography. For the diagnosis of dilating lesions of the abdominal aorta, the femoral, popliteal and carotid arteries, B-scan imaging with 3.5 MHz, 5 MHz and 8 MHz probes were utilized. Doppler arteriography and B-scan imaging with a 8 MHz probe were good diagnostic procedures for stenotic lesions of the carotid, femoral and popliteal arteries.
However, to obtain more accurate and sharp pictures of superficial vessels such as the carotid, femoral and popliteal arteries, and for the diagnosis of aortic and iliac artery occlusion, further refinements including resolution acuity, are mandatory.
