“Static vs Dynamic Diagnostic Methods: Understanding the Differences between CT, MRI, Radiography, and Ultrasound”

CT, MRI and radiography, unlike ultrasound, are static diagnostic methods, that is, the doctor takes a picture of an organ or a series of pictures of individual areas – the so-called sections. With radiography, this is more often one picture or two or three – in a direct, lateral or oblique projection, with CT and MRI – several hundred. There is also, for example, an X-ray examination with the introduction of contrast agents, when the diagnostician takes a series of pictures. As a result, it seems that it is possible to study the work of the organ in dynamics.
