Chest CT is an effective method of examining chest lesions. Among them, chest CTA refers to aortic angiography of the chest, which is important for checking whether aortic coarctation has formed, whether there is aortic dilatation, and whether there is an aortic aneurysm, among other conditions, which are important for diagnosis. Depending on the level of the hospital, there may be some difference in the charges for chest CTA. In a tertiary care hospital, for example, the cost of a chest CT scan is about$1,000, in addition to nearly$150 for a high-pressure syringe. The contrast agent to show the blood vessels costs between$150-300 depending on the size and content. The overall cost is around$1,500. The above prices are for reference only, and prices at other hospitals will fluctuate above and below that price.
