Tc-99m DISIDA is widely used for studying a variety of biliary conditions. It is generally recognized that the spleen is normally visualized on DISIDA imaging only during the blood pool phase. Upon review of our experience with DISIDA, visualization of the spleen was found more common than generally acknowledged. All DISIDA examinations performed at our two institutions were retrospectively reviewed; 95 studies were performed at Institution #1 and 150 studies at Institution #2. There were 138 men and 107 women. Quality control to confirm radiochemical purity included sephadex gel column chromatography. Of 245 patient studies, persistent splenic visualization was identified in one patient (1.0%) at Institution #1 and in 11 patients (7.3%) at Institution #2. There was no correlation between age, sex or final diagnosis and persistent visualization of the spleen. It is suggested that persistent splenic visualization may be caused by an elevated concentration of reduced hydrolized technetium (colloid) in DISIDA.

D011877	Radionuclide Imaging	The production of an image obtained by cameras that detect the radioactive emissions of an injected radionuclide as it has distributed differentially throughout tissues in the body. The image obtained from a moving detector is called a scan, while the image obtained from a stationary camera device is called a scintiphotograph.

D012189	Retrospective Studies	Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.
