Fig. 3

Example images from slab-selective 4D-MRI (a), non-slab-selective 4D-MRI (b) and 4D-CT (c) for the same patient. Red circle indicates the tumor region and green arrow indicates the involved blood vessel. d The relative image intensity profile across the tumor and aorta interface indicated by the white line on the 4D-CT image in (c), with slab-selective-4D-MRI showing higher contrast across the tumor/vessel interface than that non-slab-selective-4D-MRI and 4D-CT
