A1 Huang, Wen-Shen A1 Milan, Primo YR 2007 UL http://tech.snmjournals.org/content/35/4/252.abstract AB We present a patient with a large hiatal hernia resulting in duodenogastric reflux that was seen as abnormal activity below and behind the heart (retrocardiac) on SPECT images and on 99mTc-tetrofosmin cardiac SPECT raw-data projection images. Incidental findings such as extra- and retrocardiac activity in the thorax and abdomen should be included on all comprehensive cardiac SPECT reports.
