Abstract

We investigated and compared signal intesity and the effect of imaging the upper abdomen with blueberry juice (B. J. ), a Mn agent utilizing the properties of paramagnetic metals, and FerriSeltz (F. S.), an iron agent. Since the relaxation effect was much stronger with B. J. than with F. S., the signal intensity required of a peroral contrast agent was able to be obtained at a much lower concentration of B. J. In imaging the upper abdomen, B. J. had a positive effect on imaging in T1-weighted images, and a negative effect in T2-weighted images. F. S. had a positive imaging effect in both, and because it showed extremely high signals in T2-weighted images, motion artifact arose.
