Pulsed nuclear magnetic resonance studies on nuclear fractions of normal and malignant tissues
Abstract:
Nuclear fractions isolated from normal liver tissues and an experimental tumor--mouse fibrosarcoma (MFS)--were studied by pulsed NMR. Findings were: (1) T1 values of nuclear fractions are higher than those of the tissues or origin. (2) T1 values of nuclear fractions isolated from liver of tumor-bearers are higher than T1 values of nuclear fractions of normal liver. (3) T1 values of nuclear fractions of MFS tumor are higher than nuclear fractions of liver of tumor-bearing mice. Comparison of T1 values of the nuclear fractions shows a hierarchy of T1 from liver to MFS.

While fluorine-19 and phosphorous-31 have high natural abundances (100%) and positive gyromagnetic ratios, nitrogen-15 has a low natural abundance and a negative gyromagnetic ratio. However, nitrogen-15 is still preferred over nitrogen-14 (which has a high...
