For the detection of arteriosclerosis, vascular ultrasound is usually used. Of course, it can't detect all the arteries in the whole body, only local. For example, arterial ultrasound can be used to detect whether carotid artery and vertebral artery have arteriosclerosis, which will be very clear. In another case, you can do CT examination of arteries, which should be enhanced CT of arteries. Arteriosclerosis can also be seen by local injection of contrast media, such as coronary CT examination of the heart, which can evaluate whether the coronary artery is hardened or calcified. In another case, you can do cerebral vascular magnetic resonance examination to see if there is sclerosis. Then do angiography, cardiac angiography and cerebral angiography to see if there is arteriosclerosis. There are still many detection methods, mainly through imaging methods.
