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. (Please refer to the prices announced by the price bureaus around the world.) 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, Guangzhou and Shenzhen for such examinations that are not covered by medical insurance. The level of medical care is completely different, and PET-CT examination is an example. First, the equipment is not the same. Most of the PET-CT machines in second-tier cities are “BYD”. Secondly, the technology of experts. The technology of the experts in the north, Guangzhou and Shenzhen is definitely better than the local ones.
