Mri Contrast Agents

Famous quotes containing the words contrast and/or agents:

    In contrast to the flux and muddle of life, art is clarity and enduring presence. In the stream of life, few things are perceived clearly because few things stay put. Every mood or emotion is mixed or diluted by contrary and extraneous elements. The clarity of art—the precise evocation of mood in the novel, or of summer twilight in a painting—is like waking to a bright landscape after a long fitful slumber, or the fragrance of chicken soup after a week of head cold.
    Yi-Fu Tuan (b. 1930)

    Even though fathers, grandparents, siblings, memories of ancestors are important agents of socialization, our society focuses on the attributes and characteristics of mothers and teachers and gives them the ultimate responsibility for the child’s life chances.
    Sara Lawrence Lightfoot (20th century)
