A color and pulsed Doppler evaluation of 140 benign and malignant lymphnodes in 85 patients has been performed: The nodes have been classified into non-vascularized (flow-), normal-vascularized (flow +), and hypervascularized (flow +2); we also considered the presence of central or peripheral flow. Resistivity index was also measured. The only parameters showing statistical significance were flow - and flow +. The authors conclude that there is a higher probability of benignancy than malignancy in an avascular node, while the opposite is true in a node with moderate flow.
