For the examination of neuroblastoma, we generally recommend a neurological examination to help determine whether there are any clear positive signs, as well as to inquire about medical history and family history to judge if there are any cases of neuroblastoma among family members. Additionally, detailed laboratory tests, routine blood tests, routine urine tests, and biochemical tests, including tumor-related diagnostics, can help in making assessments. Of course, the most accurate and crucial examinations are CT or MRI scans of the head. If necessary, an enhanced MRI scan of the head can be conducted to further evaluate the location, nature, severity of the tumor, and its relationship with the surrounding neural and vascular tissues, which helps provide a basis for further surgical treatment.
