Mri Contrast Agents

Famous quotes containing the words contrast and/or agents:

    In contrast with envy, which usually occurs between two people and is focused upon another person’s qualities or possessions, jealousy occurs when a third person becomes a threat to a dyad. Jealousy involves the loss or the impending loss of a relationship that one wants to hold onto, a relationship that is vital to personal fulfillment and claimed as one’s own.
    Carol S. Becker (b. 1942)

    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)
