除临床查体外，CT、MR、超声在判断恶性神经鞘瘤的位置和形态方面已经很

In addition to clinical examinations, CT, MR, and ultrasound are already very accurate in determining the location and morphology of malignant schwannomas, but pathological diagnosis is still needed to determine the differentiation from schwannomas. Some scholars try to use PET-CT to determine the tumor The metabolic activity of the substance, and follow-up to identify the recurrence of malignant schwannoma and the hyperplasia of surrounding scar tissue.

In addition to clinical in vitro, CT, MR, ultrasound in the determination of malignant neuroblastoma location and morphology has been very accurate, but with the identification of neuropathy still needs a pathological diagnosis is still determined, some scholars try to use PET-CT to determine the metabolic activity of the tumor, and in this way to follow-up to identify the recurrence of malignant neuroblastoma and peripheral scar tissue hyperplies.

In addition to clinical examination, CT, Mr and ultrasound have been very accurate in judging the location and shape of malignant schwannoma, but the differential diagnosis still needs to be confirmed by pathology. Some scholars try to use PET-CT to determine the metabolic activity of the tumor, and then follow-up to identify the recurrence of malignant schwannoma and the proliferation of surrounding scar tissue.<br>
