摘　　要：目的:对比分析小儿神经母细胞瘤彩色多普勒超声与CT的特点。方法:回顾分析2011年6月至2013年6月36例患儿的神经母细胞瘤彩色多普勒超声及CT图像表现。结果:36例患儿中超声主要表现为腹膜后分叶状不均质实质性肿物,轮廓清或不清,内部呈混杂回声,一般呈低回声为主,伴点状或斑片状强回声钙化灶及散在液性区,腹膜后大血管多被包绕。CT主要表现为不规则软组织肿块,密度不均,内可见散在分布斑片样钙化灶,增强扫描肿块呈非均匀强化。结论:彩色多普勒超声和CT在小儿神经母细胞瘤的临床诊断中各有优势,恰当应用对提高临床诊断具有重要意义。Objective： To compare and analyze the color Doppler ultrasound and the CT diagnosis of children ＇s neuroblastoma characteristics .Methods： The color Doppler ultrasound and the CT images of 36 children with neuroblastoma who diagnosed from June 2011 to June 2013 were retrospectively analyzed .Results：Among the 36 children with neuroblastoma , ultrasonography mainly manifested retroperitoneal lobulated heterogeneous substantive tumor , outline clear or unclear , internal echoes were mixed , generally hypoechoic pattern accompanied with hyperechoic scattered fluidsonolucentarea .Many retroperitoneal large vessels were surrounded .Neuroblastoma＇s CT showed irregular soft tissue mass , non-uniform density , scattered patchy calcifications , and the enhanced CT manifested non-uniform strengthening .Conclusion： The color Doppler ultrasound and the CT have their own advantages in clinical diagnosis of children＇s neuroblastoma , appropriated application is important to improve the accuracy of clinical diagnosis .
