Marriage of CT and MRI for New Clinical Applications

X-ray CT offers a map of morphology at fine resolution and high speed. Magnetic resonance (MR) captures functional, flow-sensitive, and tissue-specific signals in excellent contrast. If a simultaneous CT-MRI scanner is constructed, we will be uniquely equipped to image intrinsic complexity and dynamic character of real biological and pathological processes, especially in heart and cancer. In this presentation, we discuss the feasibility and potential of simultaneous/contemporaneous CT-MRI, which is a next step of multimodality imaging.
