Color-coded Doppler ultrasonography is a combination of real-time sonography and duplex sonography for noninvasive imaging of arterial and venous blood vessels. In 40 patients with acute onset of scrotal pain this diagnostic procedure was correlated with the findings at surgical exploration: 11 had testicular torsion, 4 hydatid torsion, 13 spontaneous detorsion, 2 blunt scrotal trauma and 10 epididymitis. For testicular torsion color-coded Doppler ultrasonography had a sensitivity of 82% and a specificity of 100%, and for epididymitis the sensitivity was 70% and specificity was 88%. Color-coded ultrasonography readily demonstrates testicular perfusion. In cases of incomplete or early torsion some residual perfusion may be detected leading to false-negative results. Despite this fact, color-coded Doppler ultrasonography currently is the most valuable diagnostic modality in the evaluation of the acute scrotum.
彩色编码多普勒超声检查是实时超声检查和双功超声检查的结合，用于对动脉和静脉血管进行无创成像。对40例急性阴囊疼痛患者进行了此项诊断程序，并与手术探查结果进行了对比：11例为睾丸扭转，4例为附睾囊肿扭转，13例为自行扭转复位，2例为阴囊钝性创伤，10例为附睾炎。对于睾丸扭转，彩色编码多普勒超声检查的敏感性为82%，特异性为100%；对于附睾炎，敏感性为70%，特异性为88%。彩色编码超声检查能够很容易地显示睾丸灌注情况。在不完全扭转或早期扭转的病例中，可能会检测到一些残余灌注，从而导致假阴性结果。尽管如此，彩色编码多普勒超声检查目前仍是评估急性阴囊疾病最有价值的诊断方法。
