Anorectal bleeding vs penile activity. A potential diagnostic problem

Clin Nucl Med. 1984 Apr;9(4):205-7. doi: 10.1097/00003072-198404000-00008.

Abstract

Intrapenile blood pool activity may be a source of artefact in interpreting a gastrointestinal bleeding study employing Tc-99m sulfur colloid or erythrocytes. Proper positioning should avoid a false reading of rectal bleeding.
