Throughout the world, sonography is often the first and sometimes the only imaging modality to be used after clinical examination. This is particularly true for the cervical region. This book reviews the sonographic features of the cervical structures, including the thyroid, parathyroids, salivary glands, lymph nodes, larynx and hypopharynx, and blood vessels. Detailed morphological descriptions of numerous pathological processes are provided, followed by thorough discussion of differential diagnostic problems. The role of all of the new technical modalities, including high-definition gray scale, enhanced color Doppler, and ultrasound contrast agents, is fully considered. The closing chapter is devoted to the use of cervical sonography in pediatrics.
