CCDS evaluation of the arteries of the upper limbs,teries, and to the anatomic differences in the origins of the right and left subclavian arteries; it is these features which lead to the characteristic hemodynamic consequences of stenoses or occlusions of the brachiocephalic or subclavian arteries respectively, as will be discussed in more detail later in the chapter.

Color-coded Doppler sonography of the veins of the neck and upper extremities, cannot be sonographically visualized; the inferior bulb is readily demonstrated in most cases. Because of the clinical importance of the IJV, this vessel deserves special attention during sonographic evaluation of the neck.

Friihwald and Blackwell provides the source where the results of over 30 years of hard-won advances can be found. The editors and contributors summarize this burgeoning field in their lucidly written, interesting, and accurate treatise. Beginning with chapters on physical principles and technical c

Goals: Doing the Right Things Right,re deeply placed in the neck; in their midcervical course they are largely obscured by bone as they pass through the transverse processes of C6–C2. For this reason, Doppler vertebral examination is subject to difficulties and limitations not encountered in carotid studies.

Color-coded Doppler sonography of the thyroid and parathyroid glands, used depending on the depth of the particular region of interest. The use of such high frequencies allows extremely fine resolution of even small anatomic or pathologic structures within the thyroid and parathyroid glands as well as elsewhere in the neck.

Many CCDS instruments allow introduction of additional color (often green or orange) in areas where marked variation in velocity is encountered (Fig. 9); this can help visually “flag” regions of turbulent flow as are often encountered just distal to an area of stenosis.
