补充资料:电子计算机X射线断层成像
电子计算机X射线断层成像 computed tomography 医学上采用的影像诊断技术。用 X射线对人体投射,经检测器测定透射后的放射量,通过电子计算机处理,重建出人体断层图像,并作出诊断。英文简称CT。CT 机由X射线发生、数据收集、数据处理、操作及图像显示等装置和电源等几部分组成。CT图像具有比常规X射线照片高 10倍以上的密度分辨率,能清晰显示病变。CT对颅脑疾病有较高的诊断价值,是外伤、感染、脑血管疾病、先天畸形、肿瘤等的首选检查方法。对肝、胰、脾、肾等实质脏器疾病,特别是占位性病变,也有较高的诊断价值。也可用于五官、盆腔、脊柱、四肢、纵隔等部位疾病的诊断。CT 与B型超声检查配合使用,诊断率更高 。CT 对肺及消化道疾病的诊断不如常规X射线 ,但有时可起到补充作用。在一般的CT扫描机上加上一定的装置和程序,或使用专门的CT设备可以在CT图像上制订放射治疗计划,以提高疗效。 |
