[The significance of testicular scintigraphy for the differential diagnosis of the acute scrotum].

Scrotal scans were performed in 100 juvenile or grown-up patients suffering from acute scrotal pain. Employing the standard equipment of a nuclear medicine department this examination which takes only a few minutes, had a very high accuracy (93%). Especially each torsion was diagnosed correctly. Quantitative analysis of the scans did not yield additional information compared to visual evaluation, and was therefore abandoned. In three patients presenting with traumatic scrotal hematoma the testicular perfusion was judged correctly posttraumatically and in follow-up scans.
