What two radiotracers are recommended for the detection of splenic tissue?
Tc-99m sulfur colloid and Tc-99m heat-damaged red blood cells (RBCs)
CT urogram demonstrates an absence of the normal spleen in the left upper quadrant, consistent with a history of a prior splenectomy due to trauma. An abnormal round soft tissue nodule is present in the anterior midline abdomen.
Given the history and appearance, the patient was referred to nuclear medicine for Tc-99m sulfur colloid scintigraphy.
