目的探讨软组织血管瘤多排CT血管成像的影像表现方法回顾性分析临床、手术及病理证实20例软组织血管瘤CT平扫、增强和CT血管成像的不同表现结果CT平扫病灶呈软组织密度,5例灶内或灶缘见斑点状或斑块状高密度钙化灶;20例增强后病灶血管成像呈不同表现,12例动脉期瘤体内呈网状血管强化并见明显的瘤体供血动脉,其中单支供血动脉4例,2支以上多支供血动脉8例,供血动脉较对侧明显增粗瘤体内明显迂曲静脉血管6例,而静脉期瘤体表现为网状血管阴影强化8例病变动脉期瘤体不强化或仅轻微强化,且无明显供血动脉参与供血,静脉期瘤体逐渐均匀一致强化结论软组织血管瘤的多排螺旋CT血管成像可清晰显示软组织血管瘤的形态、大小、供血血管
Objective To investigate the imaging manifestations of multi-slice CT angiography in soft tissue hemangiomas.Methods The CT manifestations of soft tissue hemangiomas were retrospectively analyzed.Results CT scan showed soft tissue densities in CT scan, The lesion or plaque-like high-density calcification lesion was seen in the lesion or in the foci of the lesion. In 20 cases of enhanced lesion, angiography showed different manifestations. In the arterial phase of 12 cases, the vessels showed reticular vascularization and obvious blood supply to the tumor, There were 4 cases of single feeding arteries and 8 cases of more than 2 feeding arteries. The blood supply arteries were significantly thicker than that of the contralateral side in 6 cases of tortuous venous blood vessels, while the veins of the venous phase showed reticular blood vessel shadow enhancement in 8 cases of diseased arteries Stage of tumor is not enhanced or only slightly enhanced, and no significant blood supply artery involved in blood supply, venous phase tumor gradually homogeneous and consistent Conclusion Multi-slice spiral CT angiography soft tissue hemangiomas can clearly show the soft tissue hemangiomas shape, size, blood supply vessels
