“…The 27-MHz wide line pulsed NMR spectrometer used in our previous work (9, 1 I ) was modified to incorporate a split ring resonator probe (12,13). The resonator was constructed from a 2.5-cm diameter copper tube that was 6.9 cm long, and was tuned by =3500 pfd of capacitance that was distributed uniformly across the 2-mm gap.…”

19F free induction decay (FID) signals have been observed from the index fingers of four male and two female adult volunteers using a 27-MHz pulsed nuclear magnetic resonance spectrometer equipped with a split ring resonator probe. The value of the in vivo spin-lattice relaxation time T1 of the fluoride ions naturally accumulated in bone mineral has been determined to be 2.0 +/- 0.3 s. The shape of the observed FID signals in the inhomogeneous external magnetic field indicates that the F distribution is not uniform along the length of the finger. The fluoride ion content of the index finger (within a 65-mm length from its distal end) was measured with a sensitivity of +/- 0.5 mg F within a 30-min observation time.
