摘要
在采用稳态采集快速成像（Fast imaging employing steatly-state acquisition,FIESTA）序列图像上，主要有两种对比信号，脂肪和水为高信号，其他组织均为低信号，神经显示为低信号，在颅内有脑脊液的高信号衬托下。
Purpose： To discuss MRI features of cerebral caverous angioma according to pathology. Materials and Methods： The data of 32 cases with cerebral caverous angioma proved by pathology were analyzed retrospectively including 18 cases Gd-DTPA enhanced examina- tion. Pathology type and MRI were analysed with X2 test. Results： All the cerebral caverous angioma were solitary and could occur in any site of the brain. 24 lesions displayed mixed signal in T1WI and T2WI mulberry, net or nodulation. 5 lesions displayed high-intense signal on T1WI and isointense or low-intense signal on T2WI . 3 lesions displayed isointense or low-intense signal on T1WI and light high-intinse signal on T2WI. 23 lesions displayed peripheral ring-like low-intense signal on T2WI. In 18 enhanede eases, 7 lesions showed slight enhancement, 8 lesions showed spot or uneven enhancement, 3 lesions showed no enhancement. There were two types of cavernomas based on pathology but no significant difference appearanced on MR imaging. Conclusion： Mulberry, net or nodulation mixed signal with peripheral ring-like low signal on T2WI is MR feature of cerebral eaverous angioma.
