One of the future promising hybrid non-invasive molecular imaging techniques is positron-emitting tomography (PET) integrated to magnetic resonance imaging (MRI) to form one cross-functional PET/MRI. This paper gives an overview of the technical aspects of the PET/MRI hybrid technique. In addition, it investigates the clinical applications of PET/MRI. However, this hybrid technique aims to incorporate anatomical morphological imaging and physiological functional scanning. Nonetheless, it provides the capability to combine detailed, comprehensive visualisation of the structure (MRI) aligned with the function and optimised the ability to track metabolic processes (PET) at the optimal sensitivity. The PET/MRI together allows patients (pediatric or pregnant patients) to be scanned with a lower radiation dose than in other modalities such as PET/CT. Besides, it reduces the number of scanning appointments for patients. Given these challenges, hybrid PET/MRI module focuses on developing the technical aspects in the clinical field and tickle obstacles of the clinical practice and radiation protection.
