The cost of a CT examination is determined by the number of parts to be examined and the type of machine chosen. 16-row CT scan costs 263.2 yuan for one part, and it will cost more for an enhanced examination. 16-row CT scan plus enhancement costs more than 560 yuan for one part, plus the cost of a bottle of contrast. A normal contrast agent costs 300-400 yuan, and a more expensive contrast agent costs nearly 700 yuan, so the total cost of a 16-row CT plain scan plus enhancement for one area is 800-900 yuan for a normal contrast agent. If the patient is having a vascular examination, the cost of the examination is more than 1300 yuan, and a bottle of contrast agent is also needed, the total cost is about 1800 yuan.
