64-row CT is a type of CT with 64 rows of detectors, which allows for faster scanning speed and higher resolution, as well as multi-planar reconstruction in the cross-sectional, sagittal and coronal planes. In addition, it can also perform three-dimensional reconstruction, etc., which can better display the examination area and the details of the lesion. Compared with the ordinary 16-row CT and 32-row CT, etc., it not only has clearer images and shorter scanning time, but also has less radiation dose to patients, which has unique diagnostic value especially in cardiovascular and cerebrovascular diseases and orthopedic diseases, etc. However, compared to other machines, its price is also relatively high, generally about 350 yuan for one part, and higher for heart or special imaging.
