Using 3D APTw and ASL imaging to differentiate solitary brain metastases from glioblastomas

This study is to determine whether APTw and ASL imaging are useful for distinguishing GBMs and SBMs. The differences in APT and CBF values between GBMs and SBMs were compared. The result showed that 3D APTw is an important MRI technique for distinguishing SBMs and GBMs. Particularly, APTw combined with ASL demonstrated a more satisfactory discrimination and a higher diagnostic performance.
