Hepatic Hemangiomas and Other Hemangiomatous Lesions: MR Imaging Manifestations, Pitfalls and Problem-Solving MR Techniques

Kenji Matsuzaki¹, Mayumi Takeuchi¹, Masafumi Harada¹

Hepatic hemangiomas and other hemangiomatous tumors and tumor-like lesions may show characteristic clinical and MR imaging manifestations reflecting their pathologic features, whereas various degeneration in hemangiomas, and surrounding parenchymal changes may influence the imaging manifestations of hemangiomas. In this exhibit we demonstrate usual, unusual MR imaging manifestations of hepatic hemangiomas and other hemangiomatous lesions, pitfalls and problem-solving MR techniques: Chemical shift imaging (CSI), dynamic contrast-enhanced MRI (DCE-MRI), diffusion-weighted imaging (DWI), SPIO-MRI and Gd-EOB-MRI for making accurate diagnosis and appropriate management of the patients.
