[The clinical value of MRT in diseases of the testis and scrotum].
Since 1986 more than 150 patients with testicular carcinoma, trauma or chronic inflammation and subacute torsion were investigated with MRT. Using a 1.5 Tesla-Magnetom (Siemens) with surface coils and a special Helmholtz coil, we imaged T1-weighted, proton-density and T2-weighted coronary and axial slices. The excellent spatial resolution facilitated the imaging of fine structures as the septula testis. In 55 surgically proven cases the proof or rejection of a testicular tumour was always possible without false negative or positive cases. We were also able to correlate certain types of tumours with the imaged morphologic structure. Embryonal carcinomas showed typical focal hemorrhages. Pure seminomas showed a clean cut surface, correlating with that of the surgical preparation. The T2 image gave always a low intensity signal. Beta-HCG-positive seminomas showed different signal patterns. Inflammatory processes in epididymitis were detected, as well torsion of the testicles. In traumatic conditions a differentiation of a ruptured tunica albuginea as an indication for surgery was possible. MRT is an important contribution for the indication of urological surgery. Unnecessary surgery of the testes can be prevented, small tumours can be detected at an early stage and can be differentiated from other conditions.
