Researchers have developed VascuSR, a novel iterative anatomy-aware diffusion framework designed to improve the super-resolution of computed tomography (CT) images. This method integrates explicit 3D vascular guidance to ensure anatomical accuracy, preventing the generation of spurious or incorrect vascular details often seen in standard super-resolution techniques. VascuSR refines vascular structures using a lightweight 3D generative refiner and guides slice-wise super-resolution via an anatomy controller, with iterative feedback updating the guidance. Evaluations on the MSD Task08 and HVM datasets demonstrate that VascuSR surpasses existing interpolation and learning-based methods in segmentation accuracy and 3D vascular structure preservation, reducing connected-component counts by over 20% and mean centerline distance by over 10%.
