The Color Doppler testis or scrotum has been demonstrated to be useful in the diagnosis of scrotal lesions. It is helpful in acutely painful conditions, where it can differentiate testicular ischemia from inflammatory conditions and thus prevent unnecessary surgical explorations. With colour Doppler, useful information can be gained about vascularity in testicular malignancies. Color Doppler also has high sensitivity and high specificity in the diagnosis of lesions like varicoceles.
