It is widely used in the screening and diagnosis of various arterial and venous diseases by utilizing high-frequency ultrasound waves to trace the blood flow in real time and to detect the obstruction and abnormal structures in the blood vessels. 4, Magnetic resonance angiography (MRA) and CT angiography (CTA) is the application of magnetic resonance and CT enhancement examination to carry out image reconstruction of the target blood vessels, the use of these non-invasive methods to obtain excellent vascular images, but also an important part of the preoperative assessment. 5. Angiography: It can provide clear imaging information of peripheral blood vessels.
