Title: Detection of nuclear magnetic resonance of 17o
Inventor: ARAI TOSHIYUKI
IPC: A61B5/055
Filed: 1990-07-06
Abstract: PURPOSE:To detect <17>O existing in the form of H2<17>O in a living body and to safely obtain the information on tissue reflux and metabolic functions by taking a resonating agent contg. the <17>O at the ratio above the natural presence into the living body and subjecting the <17>O to nuclear magnetic resonance. CONSTITUTION:The gaseous oxygen in which, for example, the stable isotope element <17>O of oxygen is incorporated at the ratio (for example, 44%) above the natural presence ratio (0.037%) is used as the resonating agent. The <17>O outputs a resonance signal only when the <17>O exists in the form of the H2<17>O in the living body if the <17>O is subjected to the nuclear magnetic resonance and, therefore, the increase or decrease in the H2<17>O is known according to a change in the resonance signal with lapse of time. The cells with which the metabolism is active produce a large amt. of the H2<17>O and the cells with which the metabolism is not active produce the H2<17>O by a slight amt. each and, therefore, the state of the metabolism is recognized by a difference in signal intensity. Since the in vivo H2<17>O is carried to each tissue through the circulation, the resonance signal is kept detected and the information on the tissue reflux is obtd.
