Doppler ultrasound is able to visualize blood flow by the change in frequency (Doppler shift) of sound waves that are reflected by moving blood cells inside the vessels (Doppler effect). Since hyperemia caused by vasodilation and angiogenesis can be the earliest detectable pathologic changes in the beginning of synovitis, Doppler ultrasonography can be used to assess inflammatory activity. In a...
Although color Doppler ultrasonography has been used to evaluate testicular blood flow in many species, very little has been done in goat. Eight male Shiba goats were exposed to a single intramuscular injection of either gonadotropin-releasing hormone (GnRH group; 1 µg/kg BW) or human chorionic gonadotropin (hCG group; 25 IU/kg BW). Plasma testosterone (T), estradiol (E2) and inhibin (INH) were...
OBJECTIVE To evaluate the occurrence of reflux from the great saphenous vein by color Doppler ultrasonography in subjects undergoing treatment of insufficiency of the saphenofemoral junction by simple ligation or ligation with section of the saphenous arch.
