Radiographic Contrast or Gray Scale


Radiographic Contrast (or radiographic gray scale) is the difference between adjacent densities ranging between bright white through various shades of gray to dark black in shades of color. Why is contrast important? If a physician cannot see everything that he or she is supposed to in a given study due to poor contrast of colors then studyies [i.e. bone fractures] get misdiagnosed. If the physician is suppose to see a bright white bone it should BE white and not appear grey in color.
