目的：探讨3D-CE-MRA技术在婴幼儿体表血管瘤的应用，评估其对临床的指导价值。方法44例确诊为体表血管瘤的患儿行 MRI平扫及动态增强扫描，注药和扫描同步进行，连续采集4个血管动态时相，重建 MIP 图像显示病灶多期血管。结果MRI检出体表血管瘤数量共49个，其中单发血管瘤41例，多发血管瘤3例；3 D-CE-MRA显示有血管显影的瘤体32例37个，血管未显影的瘤体12例12个。结论 MRI平扫及动态增强图像可反映血管瘤的部位、数量和范围，并显示与周围组织的关系。3 D-CE-MRA可直接提供瘤体的血供信息。

Objective To investigate the diagnostic value and clinical significance of the three-dimensional contrast-enhanced MR angiography (3D-CE-MRA)in the infantile superficial hemangioma.Methods Forty-four children with superficial hemangioma un-derwent conventional and dynamic contrast-enhanced MRI.MRI scanning was started at the time of inj ection,and four dynamic pha-ses of images were acquired continually.Maximum intensity proj ection (MIP)images were reconstructed to show the blood vessels of the lesions in multiple phases.Results Forty-nine infantile superficial hemangiomas were detected by MRI,including a single le-sion in 41 patients and multiple ones in 3.3D-CE-MRA showed 37 lesions in 32 patients,and other 12 lesions were not found in 12 patients.Conclusion The conventional and dynamic contrast-enhanced MRI can reflect the location,number and the range of the su-perficial hemangioma,and show the relationship between the lesion and the surrounding tissues.3D-CE-MRA directly shows the blood supply of the tumors.
