| 摘 要： | 目的：初步探讨MRI增强三期扫描在评价周围型肺癌非手术治疗疗效中的作用。方法：对32例周围型肺癌患者行MRI增强三期扫描,分别在25、120、180 s行胸部扫描,记录肺癌增强前后各时相的信号值并计算强化净增值、最大强化率,与文献结果进行对照,记录120、180 s时肺癌的强化模式。结果：治疗后周围型肺癌平扫信号值、增强后120 s及180 s的信号值分别是（478±108）、（926±209）、（1 050±252）。强化净增殖（571±225）、最大强化率（119±49）明显低于文献报道的未经治疗的肺癌强化净增殖（655）（t=2.178,P=0.005〈0.05）及最大强化率（150）（t=4.196,P=0.001〈0.05）。32例中6例在180 s时表现为均匀强化,6例中4例在120 s时表现为不均匀强化,1例表现为均匀强化,1例表现为周边强化。结论：治疗后肺癌有逐渐强化的趋势;MRI增强三期扫描能够反映肺癌的血流动力学信息,是评价肺癌非手术治疗疗效的有效方法。

| Abstract: | Objective To evaluate the efficacy of three-phase contrast material-enhanced magnetic resonance imaging(MRI) in assessing no-surgical treatment response in peripheral bronchogenic carcinoma preliminarily.Methods 22 Patients with bronchogenic carcinoma after no-surgical treatment underwent three-phase contrast material-enhanced magnetic resonance imaging.Three scans were obtained at 25,120 and 180 seconds respectively after nonionic contrast material was administrated via the antecubital vein at a rate of 2m... |
