1. Real time
Early angiography can not only dynamically observe the tissue microcirculation blood perfusion information in real time, but also clearly display the classification characteristics and the situation of focal disease vessels, which improves the detection rate and the accuracy of the differential diagnosis of benign and malignant.
2. Security
Compared with dynamic CT scanning and MRI, contrast-enhanced ultrasound has the advantages of no radiation, rapid inspection and accessibility, and can be widely applied to patients.
3. Economy
Patients with severe diabetic malignant tumor risk (such as chronic hepatitis), or patients with a history of malignant tumor metastasis, must continue to undergo dynamic imaging examinations during the period. Dynamic CT scans will have radiation risks, and MRI will also bring a heavy economic burden. Early imaging is the best choice.
