Power Doppler imaging versus color Doppler flow imaging for the diagnosis of acute experimental testicular torsion



Power Doppler imaging versus color Doppler flow imaging for the diagnosis of acute experimental testicular torsion



Zhongguo Chaosheng Yixue Zazhi 16(5): 328-331



Objective: To compare the diagnostic accurracy of power Doppler imaging (PDI) and color Doppler flow imaging (CDFI) in acute testicular torsion of varied severity grades. Methods: Six dogs were surgically modelled to inflict unilateral acute testis torsion ischemia. The blood flow of the trail testis were compared with its contralateral intact one, and the changes were graded. Results: Blood flow grades was markedly lowered when torsion up grades to move than 270degree, no significamt changes when torsion eased lower than 180degree. There were no significant blood flow grades between PDI and CDFI. Conclusion: PDI can accurrately reflect changes of animal testicular blood perfusion, but it seems not surpasses CDFI.
