Cadmium (Cd) is a harmful heavy metal element. In order to decrease the cadmium content in the farm products, it is necessary to elucidate the mechanism of transport of Cd in the plant body. In this research, we visualized Cd transport in the plant body by using Positron Emitting Tracer Imaging System (PETIS) and $$^{107}$$Cd. We tried to elucidate the mechanism of Cd transport in the whole plants by analyzing the experimental data which is obtained by PETIS. We could observe that $$^{107}$$Cd signals arrive in the aerial parts of both plants in a few hours after the start of the experiment. Patterns of accumulation of $$^{107}$$Cd signals in sorghum plants were similar to those in rice plants. Strong signals of $$^{107}$$Cd were seen in the basal region of the shoot, which consists of a short stem, nodes and meristems. Interestingly, $$^{107}$$Cd also accumulated in the node strongly in oilseed rape plants although these two plants have different structure as a monocot and a dicot.
