Hepatic Arterial Buffer Response on Cross-Sectional Imaging
Abstract The primary intrinsic regulator of the hepatic artery is the hepatic arterial buffer response (HABR), which is the inverse response of the hepatic artery to changes in portal vein flow. The HABR is well seen in cross-sectional imaging as hypervascularity in areas of reduced portal vein flow...

| Summary: | Abstract The primary intrinsic regulator of the hepatic artery is the hepatic arterial buffer response (HABR), which is the inverse response of the hepatic artery to changes in portal vein flow. 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. |
