title: Ulcerative colitis and a bleeding polyp detected on Tc-99m-pertechnetate abdominal scintigraphy.
abstract: Two children with rectal bleeding were diagnosed as having ulcerative colitis and a bleeding colonic polyp respectively using abdominal scanning with Tc-99m pertechnetate. Early flow studies are recommended with careful attention paid to the amount of time abnormal areas of activity are seen on the abdominal scan.
