title: [Application of color Doppler to the head and neck region].
abstract: In the diagnosis of the head and neck region it is important to investigate the relationship between the lesions and surrounding vessels, including their hemodynamics, pre- and/or postoperatively. For this purpose color Doppler has been used in recent years. However, there is little information on the use of color Doppler in this region. This report describes an attempt to apply this examination to the region of the head and neck. Standard methods of detection of the main arteries and internal jugular vein have been devised, and the blood velocity and flow of those arteries were measured using SSA-270A convex (3.75 MHz) and linear (3.75 MHz, 2.5 MHz) array probes (Toshiba Co., Ltd.). This technique was also applied to several clinical cases. The results of these investigation were as follows. 1) The middle cerebral, vertebral and basilar, and carotid arteries and their branches could be studied. 2) Blood velocity and flow of the main arteries were reasonable when compared with the results of scintigraphy and electromagnetic studies. 3) The vessels surrounding the tumors were easy to detect. The location or hemodynamics of metastatic tumors, pseudoaneurysm, and tongue hemangioma could also be displayed. The technique was also useful for the blood flow estimation in the portion of vascular anastomosis.
