T2-weighted images (Figure 1).
The right testicle shows high signal intensities on DWI (a). In the ADC map (b), the right testicle demonstrates lower ADC value than the left testicle. On DWI (c) and ADC map (d) obtained half an hour later following the preoperative external detorsion procedure, an isointense right testicle relative to the unaffected left testicle appears, which reflects the restoration of parenchymal blood flow.

The right testicle had significantly increased signal intensity on DWI and low apparent diffusion coefficient (ADC) values compared to the left testicle (Figures 2(a) and 2(b)). The patient was diagnosed with testicular torsion based on clinical and radiological findings. The pathological signal changes in the right testicle on DWI and ADC maps detected before preoperative external detorsion disappeared and the signal intensities of the left and right testicles were almost equal (Figures 2(c) and 2(d)).
