Physiological tests and functional diagnosis with digital methods
The introduction and the continuous improvement of digital imaging techniques as digital radiography, computed tomography, magnetic resonance and ultrasound with permanent shortening of the image exposure time enable not only qualitative morphological statements but also functional analysis as quantification of function, bloodflow and perfusion basically of all organs. It may be expected that the simultaneous evaluation of morphological structures and their function may improve not only our understanding of organ function and disease mechanism but may also contribute to the earlier recognition and better staging of various organ disorders as it was already mentioned by Sir Arthur Keath in 1918: “Structure is a sure guide to function. There is no understanding of the function as long we don’t understand all parts of the structures” (and vice versa) .
