Abstract: Computed tomography systems introduced during the early 1970s have enhanced the impact of imaging in diagnostic radiology greatly. After the introduction of x-ray computed tomography (XCT), other tomographic imaging techniques such as PET, SPECT, and MRI followed and have become part of the arsenal of imaging tools used clinically and in research. Although the general notion earlier was that these imaging techniques were competing modalities this has changed greatly with the development of PET-CT technology during the last decade after realizing that acquisition of spatially co-registered complementary information was more than just the sum of its individual components. In the case of PET-CT, unlike the previous approaches using software based image fusion techniques, such a system offers the possibility of more accurate image co-registration and hence improved diagnosis for the first time. In addition to the advantage of co-registration of information from two different imaging devices, multi-modality systems also offer another unique advantage. This is due to the fact that in multi-modality systems one of the devices usually provides higher resolution images than the other. Today's presentation will discuss three such systems being developed at the Center for Functional Onco-Imaging/UCI using MRI as the high-resolution anatomic information set and integrate it with other functional imaging systems. These are: MR- optical imaging, MR-EIT, and MR-SPECT.
