Started from 1895, when Wihelm Cornrad Roentgen discovered X-rays, numerous groundbreaking findings laid the foundation for medical imaging (Riesz 1995). Since the beginning of the twentieth century, many medical imaging modalities have been used in routine clinical practice to obtain anatomical and physiological information. PET, for instance, is used for physiological imaging. Ultrasound, MRI and CT are commonly used for soft tissue structures (Weissleder and Pittet 2008). In oncology, the integrated examination (PET/CT) has gained widespread acceptance as a tool for diagnosis, staging, prognosis, treatment planning, assessment of treatment response and diagnosis of recurrence (Collins 2007, Antoch and Bockisch 2009). Although the additional CT is able to greatly aid in the accurate localization of regions of increased on PET with its high spatial resolution at the anatomical level and some basic physiological parameter information, the combination of PET with magnetic resonance imaging (MRI) has the potential to provide more advantages (Lee, Li et al. 2008, Werner, Schmidt et al. 2012).

MRI is one of the most important noninvasive diagnostic tools that is used to provide both anatomical and physiological information within living organisms in a single session with high spatial and temporal resolution (Singh, Danrad et al. 2007). The basis for MRI is similar to nuclear magnetic resonance (NMR), which is mainly the property of water hydrogen nuclei (1H) to process…
