title: A 31P topical magnetic resonance study of embryonic development in hens' eggs.
abstract: A 31P topical magnetic resonance study of whole chicken's eggs in vivo is described. Resonances from adenosine triphosphate, phosphocreatine, inorganic phosphate and phosphorous storage protein were observed. These changed in relative intensity as the embryo developed. No ill effects due to exposure to radiofrequency radiation or magnetic fields were observed. It is concluded that topical magnetic resonance can make a useful contribution to the study of embryonic development in avian eggs.
