Answer

Imaging studies are not necessary to diagnose uncomplicated ITPs. Rarely, platelet survival studies may be necessary to document decreased platelet survival before splenectomy in a patient with possible bone marrow hypofunction. Typically, the platelet half-life is decreased from the normal 5-7 days. A normal platelet survival curve is not consistent with increased splenic destruction.

In a patient who has relapsed following splenectomy, an indium-labeled platelet imaging study is sometimes useful for localizing an accessory spleen.
