Mri Contrast Agents

Famous quotes containing the words contrast and/or agents:

    Armies, for the most part, are made up of men drawn from simple and peaceful lives. In time of war they suddenly find themselves living under conditions of violence, requiring new rules of conduct that are in direct contrast to the conditions they lived under as civilians. They learn to accept this to perform their duties as fighting men.
    Gil Doud, U.S. screenwriter, and Jesse Hibbs. Walter Bedell Smith (Himself)

    Modern man’s capacity for destruction is quixotic evidence of humanity’s capacity for reconstruction. The powerful technological agents we have unleashed against the environment include many of the agents we require for its reconstruction.
    George F. Will (b. 1941)
