[Abstract]
Patients with glioma after operation and radiotherapy,once the brain have emergence of
new abnormal enhancement lesions often considering tumor recurrence or radiation - induced brain injury,
conventional MRI is difficult to distinguish it. Magnetic resonance perfusion - weighted imaging
(PWI)is a new technology that can reflect the organization of microvascular distribution and blood flow
perfusion,and provide more information to identify it. This article will review the application of PWI in
diagnosing tumor recurrence and radiation - induced brain injury in recent years.
