About this trial

The goal of this clinical trial is to evaluate the value of 99mTc-CNDG for diagnosis of brain tumors by comparing it with 18F-FDG-PET. The main questions it aims to answer are:

1. What is the diagnostic consistency between 99mTc-CNDG and 18F-FDG? 2. What is the correlation between the SUVmax value of 99mTc-CNDG and tumor type?

Participants will:

Receive18F-FDG-PET and 99mTc-CNDG examination within 2 weeks before surgery. Obtain pathological diagnosis by surgery or biopsy as the gold standard.
