Purpose: To investigate the value of dynamic and time delayed enhancement MR imaging on the diagnosis of hepatic hemangioma.
目的：研究动态增强及延迟增强扫描磁共振成像对肝血管瘤的诊断价值。
Results All 10 pigs showed delayed enhancement signal, which was confirmed to be necrotic myocardium pathologically by TTC or HE staining.
结果10头苏中猪心脏磁共振检查均有心肌的延迟增强显像。
Results Among the 25 cases, 19 cases were ischemic heart diseases, in which the delayed enhancement was subendocardium, nontransmural or transmural;
结果25例患者中，19例为缺血性心脏病，磁共振延迟强化区域为透壁和心内膜下非透壁心肌；
Conclusion: "Delayed enhancement" HCC is rare and special, the comprehensive analysis of the performance of CT and MRI can improve the diagnostic accuracy of HCC.
结论：“延迟强化”型hcc较为罕见和特殊，综合分析CT及MRI表现可提高诊断准确性。
Conclusion CEUS can rapidly enhance FLL in arterial phase but cannot diagnose it as a malignant tumor. Delayed enhancement of liver nodules is the typical feature of most benign lesions.
结论肝内结节超声造影动脉早期快速增强不能确诊为恶性病灶，但结节延迟期仍呈高增强是大多数良性病灶的特征所在。
Delayed enhanced MRI waste time and strength, rate of lesions detection was inferior to the dynamic and delayed conventional contrast enhancement. It should not be used as routine.
延迟增强扫描费时费力，检出率明显低于动态和常规延迟增强，不适应于常规应用。
