We present of a real-time, motion correction methodology for MR/PET acquisitions. Our approach utilizes self-refocused navigators that could be integrated into any pulse sequence for providing cardio-respiratory motion information after each excitation. We demonstrate that this approach improves small lesion detection sensitivity and quantitative accuracy for simultaneously acquired MR/PET scans.
