神经母细胞瘤是小儿常见的实体肿瘤,有65～75%发生在肾上腺髓质或腹膜后。确定腹部神经母细胞瘤及其扩散范围,大多数采用CT 检查,很少采用超声检查。本文介绍超声检查神经母细胞瘤的图象、诊断标准和处理。材料和方法1975～1981年用超声检查了21例在C.S.Mott 儿童医院治疗的神经母细胞瘤病人。使用手臂或静止B超声仪(探头频率3.5～5.0MHz)和机械实时扇扫超声仪(探头频率3.5～5.0MHz),14例在治疗前检查,7例治疗后检查,诊断经肿瘤活检和骨髓穿刺检查证实。病人为1～5岁儿童,15例确诊时不满2岁,6
Neuroblastoma is a common solid tumor in children, with 65 to 75% of it occurring in the adrenal medulla or retroperitoneum. To determine the extent of abdominal neuroblastoma and its spread, most of them use CT examinations and rarely use ultrasound. This article presents images, diagnostic criteria, and treatments for sonography of neuroblastomas. Materials and Methods 21 patients with neuroblastoma treated at the C.S. Mott Children’s Hospital were examined by ultrasound from 1975 to 1981. Using an arm or stationary B-ultrasonic system (probe frequency 3.5 to 5.0 MHz) and mechanical real-time fan-scanning system (probe frequency 3.5 to 5.0 MHz), 14 cases before treatment, 7 cases after treatment, diagnosis of tumor biopsy and bone marrow Puncture inspection confirmed. The patient is a child of 1 to 5 years of age. 15 cases were diagnosed when they were less than 2 years old, 6
