Arteriosclerosis is mainly detected by vascular ultrasound and angiography, and the results are relatively accurate. 1. Vascular ultrasound: atherosclerosis can be detected by vascular ultrasound. Two-dimensional ultrasound manifestations include thickening of the intima and mid-layer of the arteries, thickening and calcification of the wall, plaque formation, or accompanied by thrombus attached to the wall, and so on. 2. Angiography: It can determine the lesions of coronary arteries of the heart or cerebral arteries. Contrast agent should be injected before the examination, and it should be done with caution for those who are allergic to the contrast agent or have severe renal insufficiency. It shows luminal stenosis or aneurysm-like lesions, as well as the location, extent and degree of the lesions, and helps to determine the indications for interventional or surgical treatment and the choice of surgical methods. If atherosclerosis testing is needed, it is recommended to consult the cardiovascular department in a timely manner and use the relevant instruments under the guidance of a doctor. Meanwhile, after the test is completed, the test results need to be comprehensively evaluated, and if necessary, appropriate treatment should be carried out.
