About

The objective of this observational study is to investigate the characteristics of the tumor microenvironment in patients with brain tumors using multi-modal magnetic resonance imaging (MRI). The primary research question it aims to address is:

• Can multi-modal MRI effectively characterize features of the immune microenvironment in brain tumor patients?

Participants:

Eligible participants who have been diagnosed with a brain tumor will undergo multi-modal MRI scans for detailed assessment of tumor microenvironment features.

Enrollment: 200 estimated patients

Sex: All

Ages: 18 to 80 years old

Volunteers: No Healthy Volunteers
