The price of medical examinations varies from region to region and from level to level of hospital charges. The most expensive is Beijing, where the price of PET-CT is more than 10,000 yuan, while all other regions are basically below 10,000 yuan. The cheapest is Shanghai, which costs only 7,000 RMB. If not for the fact that it is really not very convenient for patients to travel far, it is still recommended to seek medical services in the North and Shenzhen for such examinations that are not covered by medical insurance. The level of medical care is completely different, and the PET-CT examination is an example. First, the equipment is not the same. Most of the PET-CTs in second-tier cities are BYD. Secondly, the technology of experts. The technology of the experts in the north and Shenzhen must be better than the local ones.
