Figure 2: Right epididymo-orchitis in a 31-year-old man. ( a ) Transverse T2-weighted image depicts enlargement and hypointensity of the right epididymis (arrow). Both testes appear normally hyperintense. ( b ) Transverse ADC map (b = 900 s mm-2) shows hypointensity of both testes. The right epididymis (arrow) was hyperintense on the ADC maps, due to inflammation. The ADC values of the normal left testicular parenchyma were 1.09 × 10-3 mm2 s−1. ADC: apparent diffusion coefficient.
