PCT No. PCT/JP89/00589 Sec. 371 Date Apr. 16, 1990 Sec. 102(e) Date Apr. 16, 1990 PCT Filed Jun. 12, 1989 PCT Pub. No. WO89/12422 PCT Pub. Date Dec. 28, 1989.There is carried out an NMR measurement in which a receiver coil (7) for receiving an NMR free induction signal comes in contact with or in close vicinity to one side of tissue of a living body (1) immersed in a perfusion solution (4), while a portion or whole body of the receiver coil (7) is so held as not to come in contact with the perfusion solution (4). According to this measuring method, since a portion or whole body of the receiver coil (7) does not come in contact with the perfusion solution (4), the receiver coil (7) is hardly subject to the electromagnetic influence of changes in the perfusion solution (4). This prevents the free induction signal from being embedded in noise, assuring measurement with high sensitivity. Even for a large-size internal organ, only a signal from an area presenting a uniform magnetic field may be acquired, since the measurement is carried out with the receiver coil (7) coming in contact with or in close vicinity to one side of the internal organ. Thus, a high-resolution free induction signal may be acquired.
