Perfusion - Measurement Using Nuclear Medicine Methods

Measurement Using Nuclear Medicine Methods

Perfusion of various tissues can be readily measured in vivo with nuclear medicine methods, mainly positron emission tomography (PET) and single photon emission computed tomography (SPECT). Various radiopharmaceuticals targeted at specific organs are available, some of the most common being

  • 99mTc labelled HMPAO and ECD for brain perfusion (rCBF) studied with SPECT
  • 99mTc labelled Tetrofosmin and Sestamibi for Myocardial_perfusion_imaging with SPECT
  • 133Xe-gas for absolute quantification of brain perfusion (rCBF) with SPECT
  • 15O-labeled water for brain perfusion (rCBF) with PET (absolute quantification possible when measuring arterial radioactivity concentration)
  • 82Rb-chloride for measuring myocardial perfusion with PET (absolute quantification is possible)

Famous quotes containing the words measurement, nuclear, medicine and/or methods:

    That’s the great danger of sectarian opinions, they always accept the formulas of past events as useful for the measurement of future events and they never are, if you have high standards of accuracy.
    John Dos Passos (1896–1970)

    American universities are organized on the principle of the nuclear rather than the extended family. Graduate students are grimly trained to be technicians rather than connoisseurs. The old German style of universal scholarship has gone.
    Camille Paglia (b. 1947)

    In view of the fact that the number of people living too long has risen catastrophically and still continues to rise.... Question: Must we live as long as modern medicine enables us to?... We control our entry into life, it is time we began to control our exit.
    Max Frisch (1911–1991)

    I think it is a wise course for laborers to unite to defend their interests.... I think the employer who declines to deal with organized labor and to recognize it as a proper element in the settlement of wage controversies is behind the times.... Of course, when organized labor permits itself to sympathize with violent methods or undue duress, it is not entitled to our sympathy.
    William Howard Taft (1857–1930)
