Mri Contrast Agents

Famous quotes containing the words contrast and/or agents:

    Flowers and fruits are always fit presents; flowers, because they are a proud assertion that a ray of beauty outvalues all of the utilities of the world. These gay natures contrast with the somewhat stern countenance of ordinary nature: they are like music heard out of a work-house.
    Ralph Waldo Emerson (1803–1882)

    Luckless is the country in which the symbols of procreation are the objects of shame, while the agents of destruction are honored! And yet you call that member your pudendum, or shameful part, as if there were anything more glorious than creating life, or anything more atrocious than taking it away.
    Savinien Cyrano De Bergerac (1619–1655)
