[Diagnostic value of diffusion-weighted imaging and conventional magnetic resonance imaging in testicular tumor].

Abstract

Apparent diffusion coefficient(ADC) of magnetic resonance imaging≤0.90×10^-3 mm²/s and T2-hypointensity, intratuminal septa, and peritumoral infiltration could achieve best diagnostic efficiency. ADC values and cyst or necrosis were independent predictors for the differential diagnosis of nonseminomatous germ cell tumor versus seminoma and nonseminomatous germ cell tumor versus lymphoma. ADC value and intratuminal septa were independent predictors for the differential of seminoma versus lymphoma.
