dc.description.abstract | PURPOSE: To compare the enhancement characteristics of small hemangiomas seen on multiphase spiral CT anddynamic MR imaging MATERIALS AND METHODS: Thirteen patients with 20 hepatic hemangiomas less than 25mm indiameter underwent both multiphase spiral CT and dynamic MR imaging. All lesions were assigned to one of threeclassified into 3 categories according to the enhancement pattern seen on multiphase spiral CT : typical delayedpooling, atypical early enhancement, or continuous low attenuation. The enhancement patterns seen on spiral CT andon dynamic MRI were correlated. RESULTS: On CT scans, ten lesions (50%) showed delayed pooling. Six(30%) showedearly arterial enhancement and four(20%) showed continuous low attenuation. On delayed-phase MRI, all lesionsshowed delayed high signal intensity compared to adjacent liver parenchyma. Four of six lesions with earlyenhancement on CT showed peripheral globular enhancement on early arterial-phase MRI. CONCLUSION: On multiphasespiral CT scans, small hemangiomas can show variable atypical enhancement features. In this situation,contrast-enhanced dynamic MRI is helpful for the diagnosis of hemangiomas. | - |
