Repetition of color Doppler ultrasonography: is it necessary?

Abstract

The aim of the study was to determine whether any difference would occur in peak systolic velocity (PSV) and end diastolic velocity (EDV) measurements of color Doppler ultrasonography (CDU) between proximal and distal segments of the cavernous arteries obtained at different times. Twenty-six cases have undergone CDU three times in weekly intervals. PSV and EDV measurements of cavernous arteries were obtained both proximally and distally.
