第一章 X线对比剂
普通X线摄影,X线CT平扫检查以及常规磁共振成像等,对组织间,特别是病灶内、外结构的显示分辨率不足,给临床上的定位、定性、定量诊断带来困难。因此需要引入一种物质,将其周围组织的密度或信号的差异尽可能地加大,以强烈的对比充分展示组织结构、病灶特征及其与周围器官的毗邻关系,这种物质就叫对比剂(contrast media)。对比剂引入人体后,经x线照射时,与人体组织产生明显的吸收差,使人体组织或是病灶结构显示得更为清晰,这种对比剂就是X线对比剂。
  第一节 概述
  一、X线对比剂的条件
X线对比剂与人体组织产生吸收差;无毒、刺激性小,在嗅觉、视觉、味觉上无特别感受;在检查时间内,受检器官内对比剂的蓄积有充分的浓度;检查完毕能迅速排出体外;理化性能稳定,久贮不变质;使用方便,成本低廉。
  二、X线对比剂的分类
X线对比剂通常分为阴性对比剂与阳性对比剂两大类。
阴性对比剂:与软组织相比,X线衰减系数小的对比剂,称为阴性对比剂,其特点是密度低、原子序数低、比重小、吸收X线少(如空气、氧气、二氧化碳、氮气等),在X线照片上显示为低密度或黑色影像。
阳性对比剂:与软组织相比,X线衰减系数大的对比剂,称为阳性对比剂,其特点是密度高、原子序数高、比重大、吸收X线多(如硫酸钡、碘剂),在x线照片上显示为高密度或白色影像。
