钆塞酸增强MRI对诊断小肝癌及其鉴别诊断的临床意义和应用价值

摘要/Abstract

摘要： 目的探讨钆塞酸增强MRI在小肝癌和肝内疾病诊断中的临床意义和应用价值。方法选取2014年5月至2016年5月于本院MRI扫描发现肝内存在小病灶(直径＜3 cm的57例患者,对比剂采用钆塞酸。对比分析肝内小病灶在注射对比剂前后的信号强度(SI)变化情况。并对肝胆期肝内小病灶信号强度变化及肝胆期信号变化斜率K进行对比分析。结果 57例患者中,病灶直径＜1.5 cm共27例、1.5~3.0 cm共30例。肝内小病灶在钆塞酸增强后小血管瘤易与其他疾病鉴别,小肝癌易与小转移瘤相混淆。肝胆期信号强度变化的斜率K差异具有统计学意义(P<0.05),小肝癌斜率K＜-1、而小转移瘤的斜率K＞-1。结论注射钆塞酸后有利于提高病灶的检出率和诊断率,肝胆期信号强度变化的斜率更有助于提高小肝癌的诊断准确率。
