摘要
目的 :结合海绵状血管瘤的病理改变 ,分析其 CT、MRI表现特点并比较两种检查方法对该病的诊断价值。材料与方法 :回顾分析 15例脑海绵状血管瘤资料 ,其中 CT 9例 ,MRI 6例 ,CT加 MRI检查 12例。结果 :海绵状血管瘤 CT特征性表现为平扫示类圆形高或稍高密度病灶 ,多数为不均匀 ,常伴钙化、出血。MRI特征性表现为 T1WI大部分呈等或稍高信号区 ,T2 WI一般为不均匀高信号区 ,病灶周围可见低信号环影。结论 :CT能良好显示海绵状血管瘤出血、钙化的特征 ,显示效果 CT优于
Purpose To analyze CT and MRI imaging characters of cavernous hemangioma and compare diagnostic Value of the two methods for the disease, combination with it pathologic changes. Materials and Methods The data of 15 cases with cerebral cavernous hemangioma was analyzed respectively, of these taking CT 9 cases, having MRI 6 cases, doing CT and MRI 12 Cases. Results The CT characteristic expression was analogue round with high or a litter high density changes, most of them weren't average, often companied with calcification and hemorrage. The specific showing of MRI were equal or some high signal zone in T 1WI and disagreed high signal in T 2WI, circle image was also seen in changed zone. Conclusion The characters of hemorrhage and calcification with cavernous hemangioma can been well showed by CT, the expressing effect of CT is superior to MRI.
