Abstract:
This study was undertaken to investigate the vascular patterns and resistance of normal cervical nodes by power Doppler sonography. In 101 subjects who had a sonographic examination of the neck, 1050 lymph nodes were detected. Only central vascularity was found in normal cervical nodes. The degree of vascularity in submental and submandibular nodes was higher than that in other regional nodes. Submental nodes had a higher vascular resistance in association with a lower blood flow velocity than other regional nodes. No significant difference was found in blood flow velocities and vascular resistance between male and female subjects. The vascular resistance increased significantly with age. This study provides a baseline for vascularity within normal cervical nodes, as seen by power Doppler sonography.

Detailed Structure and Function of Lymph Nodes
From a histological perspective, lymph nodes can be split into two main areas: the superficial cortex and the deep medulla. The outer cortex is populated by dendritic cells, macrophages, and B lymphocytes, which are densely packed into follicles. When these B-lymphocytes are presented...
