Inclusion criteria

Inclusion criteria: 1. Patients who have undergone surgical resection or biopsy, and are confirmed to be WHO II and WHO III gliomas by pathological examination. 2. Received radiotherapy and/or chemotherapy after surgery. 3. Have enhanced MR examination and two experienced radiologists consider the tumor recurrence. 4.

Age over 18 years old and under 70 years old, no gender limit. 6. The subject was completely voluntary and signed an informed consent form.

Exclusion criteria

Exclusion criteria: 1. Accompanied by severe heart, lung, liver and kidney and other important organ diseases, poor general condition, and obvious abnormalities in blood coagulation, the investigator's assessment or consultation with relevant departments believes that there is a contraindication, high risk or unsuitable for surgery. 2. The subject cannot undergo MRI examination. 3. The subject is unwilling to undergo another operation. 4. Pregnant or breastfeeding. 5. Life expectancy <3 months. 6. Have a serious mental illness. 7.
