PET/MRI is a hybrid imaging technology, increasingly being used in research applications as well as in clinical practice. The combined PET/MRI system is the latest in fusion imaging. The device provides specific molecular information related to cell surface receptors and enzymes and gene expression with high sensitivity, delivered by PET. Simultaneously, it also captures important anatomical data, superior soft tissue contrast, spatial resolution and information about perfusion and permeability, shown by MRI. Therefore it proves to be a highly sensitive and evaluator clinical investigation technique. PET/MRI is an expensive technology and its availability is extremely limited across the world. It still need further technical and clinical upgradations for better prospects and prove beneficiary towards the patients. However, initial experience with this new imaging system is very promising for oncology, cardiac imaging and neuro imaging. Not only pediatric and young oncologic patients but pregnant women would also be benefitted from PET/MRI. There are potential competitive advantages of PET/MRI over PET/CT. But, it is struggling to show its superiority over its arch-rival PET/CT in many cases. The aim of this paper is to review the current status of PET/MRI in clinical applications and its challenges.
