作者收集了11例临床上拟诊为单侧或双侧视网膜母细胞瘤,其中9例有典型的眼底镜表现,1例为Coats病(渗出性视网膜病),另1例因钙化不易与视网膜母细胞瘤鉴别。全部病例均行高分辨CT与MRI检查。男8例,女3例,年龄1个月到7岁。MRI场强为0.5T,表面线圈直径为12cm,与冠状面平行放置;获得横断面、冠状面、矢状面T_1加权象与T_2加权象。层厚3mm,层距0.3mm,矩阵179×256,扫描野180mm。同时用头部线圈获得脑部横断面T_2加权象。静脉注射泛影葡胺100ml后,用高
The authors collected 11 cases clinically diagnosed as unilateral or bilateral retinoblastoma, including 9 cases of typical fundopulmonary manifestations, 1 case of Coats disease (exudative retinopathy), the other case of calcification is not easy and Retinoblastoma identification. All cases underwent high-resolution CT and MRI examination. 8 males and 3 females, aged from 1 month to 7 years old. MRI field strength of 0.5T, the surface coil diameter of 12cm, placed parallel to the coronal plane; obtained cross-sectional, coronal, sagittal T_1-weighted image and T_2-weighted image. Layer thickness 3mm, layer spacing 0.3mm, matrix 179 × 256, scan field 180mm. At the same time, the head coil was used to obtain the brain T 2 weighted image. After intravenous diatrizoate 100ml, with high
