Sonography of peripheral lymph nodes part 2: Doppler criteria and typical findings of distinct entities.

Doppler sonographic criteria for assessing peripheral lymph nodes ! Introduction B-mode criteria provide the foundation for the sonographic identification of peripheral lymph nodes as normal or pathological and for differential diagnosis. “Sonography of Peripheral Lymph Nodes Part 1: Normal Findings and B-Image Criteria” therefore provides a comprehensive description of the sonographic appearance of normal peripheral lymph nodes in the individual regions of the body and of the B-mode criteria of pathological peripheral lymph nodes [1]. Color/power Doppler and pulsed Doppler sonography is only of secondary importance for the evaluation of peripheral lymphadenopathy compared to B-mode sonography [2]. This requires equipment with high-quality Doppler (color/power Doppler, pulsed Doppler).
