[Radionuclid szintigraphy of spleen alterations (author's transl)].

Selective or systemic imaging of the spleen by visualization of the reticulo-endothelial system together with the liver represents a non-invasive, innocuous examination. This study is indicated in diagnostically unclear diseases of the left upper abdomen with reference to splenic lesions. Spleen scan is able to demonstrate splenic enlargement which is not detectable in 70% of clinically examined patients. Suspicion for rupture or hematoma of the spleen with imminent delayed rupture represents an important up to now neglected indication for scanning. It should be performed prior to angiography. In liver cirrhosis, combination of liver and spleen scan gives important information about splenic size and radiopharmaceutical uptake. Splenic infarcts, tumors, cysts, and abscess may be recognized by spleen scan in different projection.
