By color-coded duplex sonography moving structures are visualized as red or blue colors within a normal gray-scale B-mode ultrasound image. Thus, blood flow even within small vessels can be visualized clearly. Color-coded duplex sonographic examination was performed in 11 patients who presented with scrotal pain. This method proved to be reliable to differentiate between testicular torsion and testicular inflammation. By clearly demonstrating a lack of intratesticular blood flow in testicular torsion, while avoiding flow in scrotal skin vessels being misinterpreted as intratesticular blood flow, this method significantly decreases the number of patients in whom surgical evaluation is necessary to exclude testicular torsion.
通过彩色编码双功超声检查，在正常灰度B模式超声图像中，运动结构可显示为红色或蓝色。因此，即使是小血管内的血流也能清晰显示。对11例阴囊疼痛患者进行了彩色编码双功超声检查。该方法被证明在鉴别睾丸扭转和睾丸炎方面是可靠的。通过清晰显示睾丸扭转时睾丸内无血流，同时避免将阴囊皮肤血管内的血流误判为睾丸内血流，该方法显著减少了为排除睾丸扭转而需要进行手术评估的患者数量。
