PET imaging in patients with meningioma-report of the RANO/PET Group

Area of Science:

• Neuro-oncology
• Medical Imaging
• Radiology

Background:

• Meningiomas are the most common primary brain tumors, accounting for 30% of all brain tumors.
• Current diagnosis and treatment planning rely on MRI and CT, which have limitations in tumor delineation and assessing post-treatment changes.
• Molecular imaging, specifically PET, is increasingly used in meningioma management.

Purpose of the Study:

• To provide evidence-based recommendations for using PET imaging in the clinical management of meningiomas.
• To highlight the advantages of PET over conventional structural imaging for meningioma assessment.

Main Methods:

• Review of studies validating PET imaging in meningioma patients.
• Evaluation of PET's ability to characterize metabolic and cellular features.
• Correlation of PET findings with histological or clinical course data.

Main Results:

• PET imaging provides clinically relevant information beyond structural MRI or CT.
• PET can aid in overcoming limitations of MRI/CT for tumor delineation and post-therapeutic change diagnosis.
• The use of PET in meningioma patients is growing.

Conclusions:

• PET imaging is a valuable tool for the clinical management of meningiomas.
• Recommendations are provided for integrating PET into meningioma patient care.
• PET enhances diagnostic accuracy and treatment monitoring for meningiomas.
