Ultrasound Examination Of Superficial Pathological Lymph Node

Objective:To discuss the ultrasound identification value of normal,benign and malignant superficial tumescent lymph nodes.Methods:The L/S ratio,interior echo,CDFI,DPI manifestation and PWD frequency spectrum feature of the superficial lymph nodes in 132 normal,patients benign nodes and malignant nodes were studied with color Doppler ultrasound.Results:The L/S ratio of the four groups including normal lymph node,benign and malignant lymphadenectasis were 3.14±0.21,1.94±0.22,1.46±0.27,medullary truncus arteriosus Vmax were(7.9±0.30)cm/s,(12.8±0.42)cm/s,(13.5±0.78)cm/s,(11.6±0.21) cm/s and RI were 0.56±0.04,0.71±0.03,0.74±0.03,0.70±0.04 respectively.It has obvius differences of the four quotas(P＜0.05).Interior echo of benign tumescent lymph nodes displayed wider and brighter of the medulae and narrow of the cortices,but the malignant tumescent lymph nodes were on the contrary.CDFI showed the blood flow of the most benign tumescent lymph ondes displayed more abundant and regular,and the blood flow of most malignant lymph nodes displayed disoredr and irregular.All the DPI displayed sensitive than CDFI.Conclusions:Color Doppler ultrasound identification and diagnosis of benign and malignant lymphadenectasis has its edges possibly being the first trial method.
