title: Duodenogastric reflux in a hiatal hernia seen as retrocardiac activity on 99mTc-tetrofosmin cardiac SPECT raw-data images.
abstract: 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 (99m)Tc-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.
