Abstract：Objective: To investigate the diagnosic and differential diagnosic values of color Doppler flow imaging(CDFI) for testicular torsion and testicular appendage torsion. Materials and Methods: A total of 44 cases of testicular torsion and 37 cases of testicular appendage torsion were analyzed and concluded by CDFI reviewed. Results: The specific sonographic signs of testicular torsion were that the blood flow was diminished or absent in the testicle, and there was a hyperechoic mass with no blood flow above the testicle. The specific sonographic signs of testicular appendage torsion were that unequal hyperechoic node with no blood flow was found between or beside testicle and head of epididymis as well as the blood flow was slight increased in the testicle and epididymis. Conclusion: CDFI has a great value in diagnosis of testicular torsion and testicular appendage torsion.
