Testicular scanning: a new modality for the preoperative diagnosis of testicular torsion.

A simple, safe and rapid scanning procedure using 99-m technetium is described for the diagnosis of torsion of testicles. The procedure is especially useful in the adult with an enlarged scrotum of recent origin in whom the surgeon cannot clinically differentiate torsion of the testicle from epididmitis. It is not suggested that this procedure replace immediate scrotal exploration in the acutely illpatient.
