Imaging transgenic animals

Transgenic and eugenic animals as small as 30 g can be studied noninvasivel y by radionuclides with resolutions of 1-2 mm, by MRT with resolution of 10 0 mu m and by light fluorescence and bioluminescence with high sensitivitie s. The technologies of radionuclide emission, magnetic resonance imaging, m agnetic resonance spectroscopy, optical tomography, optical fluorescence an d optical bioluminescence are currently being applied to small-animal studi es. These technologies and examples of their applications are reviewed in t his chapter.
