The internal structures of rat fetuses on day 18.0 of pregnancy were studied by magnetic resonance imaging in 1‐mm sagittal slices. Each organ was represented as white to gray images different in tone according to the 1 H proton content and the relaxation time. In solid organs, portions with high cell density were seen as white areas and those with low cell density as gray areas. In the tubular organs, the margins were imaged as white and the lumina as gray.
