title: Testicular torsion and usefulness of radionuclide scanning.
abstract: The usage of the testicular scan to differentiate torsion from epididymo-orchitis in 33 patients is reported. Our results yielded a surgically confirmed accuracy rate of 77 per cent, and a clinical accuracy rate of 100 per cent. The entity of missed torsion has a characteristic appearance, which we have termed the "halo sign."
