Planar + SPECT/CT of the representative patient where the site of bleeding could be detected. Planar images (a 3 h after radioisotope injection, b 6 h after, c 24 h after) and SPECT/CT images (d SPECT, e CT, f SPECT/CT, 6 h after radioisotope injection). No abnormal uptake was noted in planar images at 3 h after radioisotope injection (a). A spotty uptake was seen in the right lower abdomen in planar images at 6 h after the injection (arrow) (b). In the planar images at 24 h after the injection, a diffuse uptake was seen in the ascending and descending colon (arrowheads) (c). In SPECT/CT images at 6 h after the injection, the spotty uptake matched the distant jejunum (d, e and f) (arrows). It was revealed to be small intestinal metastasis of colon cancer
