摘要
Benign hepatic vascular neoplasms and vascular pseudolesions are commonly encountered in magnetic resonance (MR) imaging. Most of these benign lesions demonstrate not only arterial-phase hyperintensity, but also persistent enhancement on venous and delayed imaging, unlike most malignant hepatic masses. These features, along with other MR findings and morphological characteristics, may allow for more confident diagnosis and distinction from hepatic malignancy. The objective of our study was to illustrate the MR imaging findings of hepatic lesions that demonstrate both early arterial and sustained enhancement on hepatic venous and delayed phase.
