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。
Purpose: To investigate the value of dynamic and time delayed enhancement MR imaging on the diagnosis of hepatic hemangioma.
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。
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.
结论MRI动态增强扫描、常规延迟增强扫描提高了病灶的检出率，其中以动态增强扫描病灶检出率最高。
Conclusion Dynamic enhanced and conventional delayed enhanced MRI improved the rate of lesion detection, and the Dynamic enhanced MR was the most sensitive in detecting lesions.
