title: Evaluation of vascular patterns of cervical lymph nodes with power Doppler sonography.
abstract: Power Doppler sonography was used to evaluate 105 benign and malignant cervical lymph nodes in 60 patients. Three main vascular patterns were identified: type I (single vascular pole), type II (hypertrophic vascular pole), and type III (mainly peripheral vascularity). The first one was related to chronic inflammation (sensitivity 85%, specificity 90%); the second and third were related, to a lesser extent, to acute inflammation and neoplasm (sensitivity 68% and 55%, specificity 47% and 91%, respectively). The authors conclude that the sensitivity and specificity of power Doppler sonography cannot compete with those of fine-needle aspiration biopsy in the diagnosis of adenopathy.
