Purpose : This study evaluated the effectiveness of power Doppler ultrasonography by comparing power Doppler imaging to color Doppler imaging of the blood flow around the submandibular gland. Methods : Ultrasonographic examinations were performed with a SSD-1700 (Aloka Co., Japan) equipped with a linear electronic scanner using a 7.5MHz probe. Twenty-five healthy volunteers with no history of submandibular gland diseases were examined ultrasonographically. In the facial artery, the submental artery, the lingual artery, the palatine ascending artery, the suprahyoid branch of the lingual artery and the branch of the external carotid artery around the submandibular gland, ultrasonographic images obtained with power Doppler and color Doppler were compared. Results : The power Doppler was appeared more sensitive to demonstrate blood flow of the branch of the facial artery, the submental artery, the lingual artery, and the palatine ascending artery, which are inside and outside of the submandibular gland, but there was little difference in the sensitivity to blood flow in the main arteries. It was difficult to demonstrate blood flow of the suprahyoid branch of the lingual artery and the branch of the external carotid artery. Conclusion : The results showed that power Doppler imaging is more valuable to demonstrate blood flow around the submandibular gland.
