Abstract: Neuroblastoma is the most common extracranial solid tumor,which accounts for 10% of children's tumor.The prognosis is closely related with its clinical grading.And the diagnosis of imaging can provide valuable information for clinical treatment and follow-up.MIBG scintigraphy,somatostatin receptor scintigraphy,radioimmunoscintigraphy,bone scan and PET mainly show the functional status of tumor and its metastases;CT and MRI present more detailed and exact data in anatomy.Each modality has its specified character and works well when combined with each other.
