A magnetic resonance and positron emission tomography (MR-PET) hybrid scanner workflow for providing a scout scan (topogram) of a patient includes (a) positioning the patient in the MR-PET hybrid scanner (b) referencing the patient to the scanners field of view (c) specifying the patient parameters for MR and PET hybrid topogram scan (d) performing hybrid MR-PET topogram scan and acquiring MR topogram scan data and PET topogram scan data simultaneously and (e) reconstructing the MR and PET topogram scan images in real-time and (f) presenting the topogram san images as a fused topogram data set.
