Methods: Select cases of neonatal brain, children ’ s pancreas, suspected children ’ s colon polyp and children ’ spelvic cavity, 30 cases of each, the same child was examined by convex array high frequency probe and linear array highfrequency probe respectively, to analyze the display rate and image quality of tissues shown by small convex array probe andlinear array high frequency probe. Results: The image quality presented by small convex array high frequency probes on chil-dren ’ s brain, pancreas, colon polyp and uterus is significantly higher than that by linear array high frequency probes, withremarkably higher display rate of pediatric pancreas and colon polyp than linear array probes. Conclusion: Small convex arrayhigh frequency probes can significantly improve the image quality of children ’ s brain, pancreas, colon polyp and uterus, andimprove the display rate of pancreas and colon polyps of children.Key words: Abdomen; Child; Ultrasonography[ 收稿日期 ] 2019-03-11 ; [ 修回日期 ] 2019-04-28[ 作者简介 ] 杨坡( 1985- ),男,河南郑州人,主治医师。 E-mail : yangpo909@163.com[ 通讯作者 ] 栗河舟,郑州大学第三附属医院超声科, 450052 。 E-mail : lihezhou67@126.com[ 基金项目 ] 河南省科技厅重点研发与推广专项( 182102311200 )。
