In recent times the traditional radiography is more and more replaced by digital radiography, using digital X-ray sensors instead of photographic film. Advantages include time efficiency through bypassing chemical processing and the ability to digitally transfer and enhance images. Also, less radiation can be used to produce an image of similar contrast to conventional radiography.
Since the more sophisticated imaging techniques (MRI, CT scan) provide a much higher image quality and a better ratio of diagnostic information to radiation exposure (MRI has none), we use radiography just in selected, uncomplicated cases.
