For neuroblastoma, the examination items mainly include the patient's vital signs and physical examination, including detailed examinations to observe if there are any obvious pathological signs. Additionally, it is necessary to inquire about the patient’s medical history, especially past medical history and family history. Main examination items include laboratory tests, routine blood and urine tests, biochemistry, and tumor-related tests. Furthermore, examinations also involve using a cranial CT scan, MRI of the head, and if necessary, an enhanced MRI scan of the head, to further determine the presence of neuroblastoma, as well as its location, quantity, and the relationship between the surrounding tissues, blood vessels, and nerves.
