Higher expression of BP antigen was observed in popliteal fossa, antecubital fossa, upper back, lower back, medial side of thigh and lower abdomen. 窝、肘窝、上背、下背、股内侧和下腹部皮肤BP抗原表达率较高;
Higher expression of EBA antigen was observed in knee, popliteal fossa, dorsum of foot, antecubital fossa, elbow and lower abdomen. 膝、阳窝、足背、肘、肘窝和下腹部皮肤EBA抗原表达率较高。
0.2 mmol/ kg of Gd-DTPA was injected rapidly by hand from an antecubital vein. A breath-hold 3D FLASH sequence ( TR/ TE 4.6 ms/ 1.8 ms) was performed in the coronal plane to obtain three groups of source images. 从肘静脉快速推注Gd-DTPA0.2mmol/kg,用3DFLASH序列(TR/TE4.6ms/1.8ms)屏气冠状位扫描获得3组三维原始图像,行最大信号投影处理。
