Oxygen-17 relaxation times in the blood sera of rats with various cancers. Can a systemic effect be detected?
17O NMR relaxation times of water in the serum of rats with various cancers were measured. No systemic effect could be detected at 4.7 and 8.4 T. The serum T1(17O) value was 7.6 +/- 0.5 ms at 37 degrees C independent of the magnetic field. T2(17O) was approximately half T1(17O). The 17O relaxation times could be determined at a faster rate than the 1H relaxation times.
