Static and dynamic radionuclide imaging in the diagnosis of the acute scrotum.

In the acute scrotum, diagnosis can be difficult in certain cases. In 107 patients the value of static and dynamic radionuclide imaging was evaluated. Static images provide a sensitivity and reliability of over 90%. Quantitative measurements do not give additional information in the differential diagnosis of these patients. Generally, scintigraphy can only be advocated if available as an emergency procedure. It is not necessary in cases with clinically obvious diagnosis of acute testicular torsion or epididymitis, but can be very helpful and reliable in unclear cases, i.e. for the evaluation of testicular perfusion after scrotal trauma.
