Which Doppler finding is most commonly associated with acute testicular torsion?

In acute testicular torsion, twisting of the spermatic cord abruptly cuts off arterial inflow to the testis. On Doppler ultrasound, the most telling sign is absence of intratesticular blood flow, which reflects arterial occlusion. This finding is highly specific for torsion and is a urgent clue that the testicle needs rapid evaluation to attempt salvage. Other scenarios fit different patterns: increased intratesticular flow suggests inflammatory processes like epididymo-orchitis rather than torsion; normal flow can occur in very early or intermittent torsion or if the lesion is not yet fully obstructed; delayed venous filling is possible but less reliable as a sole indicator of torsion.
