RT Journal Article SR Electronic T1 Multimodality Brain Tumor Imaging: MR Imaging, PET, and PET/MR Imaging JF Journal of Nuclear Medicine JO J Nucl Med FD Society of Nuclear Medicine SP 1554 OP 1561 DO 10.2967/jnumed.113.131516 VO 56 IS 10 A1 James R. Fink A1 Mark Muzi A1 Melinda Peck A1 Kenneth A. Krohn YR 2015 UL http://jnm.snmjournals.org/content/56/10/1554.abstract AB Standard MR imaging and CT are routinely used for anatomic diagnosis in brain tumors. Pretherapy planning and posttreatment response assessments rely heavily on gadolinium-enhanced MR imaging. Advanced MR imaging techniques and PET imaging offer physiologic, metabolic, or functional information about tumor biology that goes beyond the diagnostic yield of standard anatomic imaging. With the advent of combined PET/MR imaging scanners, we are entering an era wherein the relationships among different elements of tumor metabolism can be simultaneously explored through multimodality MR imaging and PET imaging. The purpose of this review is to provide a practical and clinically relevant overview of current anatomic and physiologic imaging of brain tumors as a foundation for further investigations, with a primary focus on MR imaging and PET techniques that have demonstrated utility in the current care of brain tumor patients.
