PET-MRI synergy in molecular, functional and anatomical cancer imaging

摘要: In the wake of PET-CT, development PET-MRI scanners marks another milestone in ongoing quest for high-sensitivity and high-specificity biomedical images offering exquisite morphological detail. But why need PET-MRI? First, although well established routine clinical practice, has two disadvantages compared with PET-MRI: it does not really allow simultaneous data acquisition, exposes patient to a significant radiation dose. Second, high-resolution, very high contrast imaging soft tissues, spectroscopy, functional are all features that only MRI offers. It may be easier appreciate value if one understands different roles PET MRI, their combined use (in fusion or side-by-side analysis), advantages performing both scans concurrently. The strenuous efforts develop scanning technology at last yielding tangible results. A look some most recently published papers this field help us get these concepts into focus.
