You can’t simply judge which is more accurate, CT or X-ray, because the scope of use of the two is not the same, for example, CT is suitable for most of the diseases of the whole body, in the head, chest, abdomen, etc. is more accurate than X-ray, because CT is a tomography, the resolution of the density is higher, the tissues and organs do not have overlapping images. x-ray has overlapping images, the resolution of the density of the lung foci is lower, the foci can easily be obscured, thus resulting in missed diagnosis. Lesions are easily obscured, resulting in missed diagnoses.X-rays have a unique application in fractures. X-rays have a unique application in fractures, and CT can be used to determine different aspects of a fracture, and in some cases CT and X-rays are complementary. Patients cannot simply say which test is more accurate, but rather which test is more appropriate for them.
