PET/MR has come a long way since 2007, when the first device integrating both technologies was developed, according to a paper published in The Journal of Nuclear Medicine. "Given the complementary nature of each modality's strengths and weaknesses, integrating PET and MR imaging offers the opportunity to gain in a single examination many of the positive attributes of both and mitigate some of their limitations," researchers said. PET/MR has shown it can improve imaging of cancers of the head and neck as well as the pelvis, and the approach is useful for non-malignant growths, the study said. PET/MR is also showing future potential for imaging neuropsychiatric conditions and Alzheimer's disease, and it can be useful in patients whose radiation exposure must be limited.
