Abstract:
48 patients with scrotal pathology were examined by magnetic resonance tomography (MRI) and computed tomography (CT). The diagnostic results were compared to surgical and histological findings. The correct diagnosis could be detected in 81% by CT and in 85% by MR. Another 27 patients were examined only by MR with positive results in 88%. Demonstration of tunica albuginea, imaging of testes in various planes and diagnostic accuracy in about 88% with missing ionising irradiation make MRI the most reliable diagnostic imaging in the classification of scrotal pathology. False negative results were found in 1/48 by CT and none by MRI. False positive results could be found in 2/75 of MRI examinations but none in CT.
