Abstract Meningiomas are the most common type of primary intracranial tumour. Histopathology-based WHO grading remains the standard for guiding management in most institutions, although new molecularly driven classification tools have been shown to improve prognostic accuracy and could guide personalized management decisions.

INTRODUCTION Molecular imaging is the in vivo visualization, characterization, and quantification of biologic processes at the cellular and molecular levels, with specific probes assessing physiologic and pathologic pathways. Cancer molecular imaging is the noninvasive visualization of processes unique to or altered in neoplasia, such as proliferation, glucose metabolism, and receptor expression, as well as the interaction of tumor cells with their microenvironment.
