【摘要】Objective To research the standardization process of high-frequency color doppler ultrasound diagnosis in pediatric mesenteric lymphadenitis. Methods The characteristic of high-frequency color Doppler ultrasound images were analyzed to 60 healthy children (control group) and 100 children with mesenteric lymphadenitis (study group) which were divided into 1-3 years, 4-5 years and 6-7 years group. The accuracy of longitudinal diameter(L), transverse diameter (S), aspect ratio (L/S), color Doppler blood flow signal classification and pulsed Doppler resistance index were evaluated. Results Mesenteric lymph nodes in the study group almost around the navel and the right lower abdomen. All the nodes distributed liking star dotted, ribbon and dendritic. Compared with the control group, L and S in all age groups of the study group were significantly higher (t values for L and S are 27.011 and 34.145 with P<0.001 respectively). The color Doppler blood flow signal classification also exist significant differences between control group and study group (x2 values are 15.732, 19.253 and 8.012 with P<0.05 respectively) and the plused Doppler resistance index were
