PET/MRI: A new technology in the field of molecular imaging

Abstract

BackgroundThe introduction of the new simultaneous PET/MRI scanner opens new opportunities in functional imaging.Sources of dataThis article is based on the literature review and our personal experience of the first simultaneous PET/MRI scanner in the UK.Areas of agreementPET/CT is well established and a key component of management guidance in a range of diseases. MRI has superior soft tissue resolution, which is useful in the evaluation of many diseases.Areas of controversyThere are currently no guidelines regarding clinical use of PET/MRI, and those centres with a PET/MRI facility are undertaking research to look for a 'key application'.Growing points and areas timely for developing researchThis review briefly describes some of the technical advances, present comparisons with the diagnostic performance of current imaging modalities (PET/CT and MRI) and identifies potential indications and research directions. © The Author 2013.
