Assessment of acute scrotum by Doppler color flow imaging: A report of four cases.

We used an Aloka SSD-2000 ultrasound unit with a 5 MHz convex scanner to assess one case of torsion of the spermatic cord, one case of orchitis, and two cases of epididymitis. Color flow imaging showed absence of blood flow signals in the testis in the case of torsion of the spermatic cord, while blood flow signals in the scrotum were significantly increased in the cases of orchitis and epididymitis. Blood flow signals decreased after chemotherapy. Color flow imaging may thus prove useful in the diagnosis and follow-up of patients with acute scrotum.
