The HABR is well seen in cross-sectional imaging as hypervascularity in areas of reduced portal vein flow. This resource was created to educate radiologists and clinicians about the HABR and its implications so as to prevent inaccurate diagnosis of pathology. It features cross-sectional images and narrative to depict the HABR. Reviewing the resource takes about half an hour. Educational Objectives By the end of this resource, learners will be able to: Understand the hepatic arterial buffer response (HABR) and its clinical implications.Educate radiologists and clinicians about HABR and its implications so as to prevent inaccurate diagnosis of pathology.
