Finding the difference between CTA and imaging?

CTA and imaging are different from the first aspect, CTA will be cheaper than imaging, there are elderly people at home who have done similar examinations in the Ping An Health Testing Center, as for the specific operation difference, I don't know, you can consult a professional doctor.

I have a friend who works as a medical guide at Ping An Health Testing Center, and she said that the two types of people are suitable for different people, and the scope of examination is also different. And one is non-invasive, the other is invasive, you can also go down.

In medicine, it is also called non-traumatic angiography technology (referred to as CT angiography or CTA), angiography is an interventional detection method, the contrast agent is injected into the blood vessels, because X-ray does not penetrate the contrast agent, angiography is to use this characteristic to diagnose vascular lesions through the image displayed by the contrast agent under X-ray.

CT scan, is a kind of computer X-ray tomography technology abbreviation, mainly according to the different tissues of the human body to the X-ray absorption coefficient of the different measurements, and then the measurement of the data into the computer, electronic.

A cross-sectional or stereoscopic image of the inspected part formed by computer processing the data. It is difficult to show small blood vessels with ordinary CT scans, even with simple contrast-enhanced CT scans.

It is easy to show the overall appearance of the blood vessels in the neck and brain, so if you need to understand the specific situation, then CTA can be a valuable test.

CTA is also called non-traumatic.

Angiography technology is a reconstruction method carried out after enhanced CT scanning, which simply means that a certain contrast agent is injected into the blood vessel during the scan to fill the vascular lumen and collect its data, and then it is reconstructed by computer.

The content of the non-interest area is deleted, and only the image of the blood vessel is retained and the overall and multi-angle reconstruction is carried out, so that the overall appearance of the blood vessel can be fully displayed, and it is also conducive to the display of diseased blood vessels. This is similar to a digital subtraction check (but CTA

3D image information can be provided). Compared to a normal CT scan, it only adds to the process of injecting drugs.

To put it simply, CTA needs the assistance of drugs, but it is a little more accurate, a little more high-end, and can be imaged in three dimensions.

CTA and contrast are different in terms of surgical methods, suitable populations, cost, and whether there is an invasive. I need to remind you that if you are doing CTA, you should pay attention to whether you are allergic to iodine, my elderly did relevant examinations when they did CTA at the Ping An Health Testing Center, and they can only be checked if the indicators are met.

I know a little bit, CTA and angiography are used to check the condition of the coronary arteries, CTA is a preliminary examination, angiography is relatively more accurate, I know the doctor of Ping An Health Testing Center told me that angiography is the gold standard of examination, and you can listen to the doctor's advice on which examination to do.
