Later, the appearance of contrast agents, the X-ray range of applications extended to those with less natural contrast tissue systems (such as the gastrointestinal tract, bronchi, blood vessels and ventricles, etc.) as the basic method of traditional X-ray diagnostic techniques, but also in the world The first universal non-invasive visceral detection methods.
