(a,b) Gray-scale and Colour Doppler of testicular torsion. In the early phases of torsion (1–3 hours), testicular echogenicity appears normal. With progression, enlargement of the affected testis and increased or heterogeneous echogenicity are common findings. A definitive diagnosis of complete testicular torsion is made when blood flow is visualized on the normal side but is absent on the affected side .Incomplete torsion refers to cord twisting of less than 360°, in which some arterial flow persists in the affected testis .
