Role of color doppler in scrotal lesions.

Color Doppler USG of the scrotum has been demonstrated to be useful in the diagnosis of scrotal lesions. Gray-scale USG characterizes the lesions as testicular or extratesticular and, with color Doppler and power Doppler, flow and perfusion can also be assessed. Color Doppler is particularly helpful in acute painful conditions, where it can differentiate testicular ischemia from inflammatory conditions and thus prevent unnecessary surgical explorations.
