The price of a single chest CT ranges from about $200 to $800, depending on the CT equipment, the type of CT, and the grade of the hospital. Chest CT, also known as computed tomography, shows the tissue density distribution map of the whole chest, the image is clearer than the traditional chest X-ray, the resolution is higher, the detection rate and diagnostic accuracy is relatively high. CT equipment is mainly categorized into single-layer spiral CT and multilayer spiral CT. At present, hospitals mainly use multilayer spiral CT, including 16-layer spiral CT, 64-layer spiral CT, etc. The higher the number of layers, the more advanced the equipment. The higher the number of layers, the more advanced the equipment, the higher the resolution, and the higher the price. Chest CT mainly includes plain scanning, enhancement scanning, CT imaging and so on. Chest plain scan is the simplest and relatively cheapest, while enhanced CT and CT imaging are more expensive. There is also a big difference in the charges for chest CT between secondary and tertiary hospitals, with tertiary hospitals charging more. Taking 64-slice spiral CT as an example, in ordinary tertiary hospitals, the price of chest CT scanning is about 300 RMB, chest CT enhancement is about 500 RMB, and special chest CT imaging is about 800 RMB. While in general second-class hospitals, the chest CT scan is about $200. So, the comprehensive estimated cost of chest CT is about $200 to $800.
