【摘要】 目的:研究颈部良、恶性淋巴结氢质子波谱特点。方法:42例颈部淋巴结,其中,良性淋巴结节组20例、恶性淋巴结组22例。均行常规MRI扫描及氢质子波谱检查。在工作站上测量Cho/Cr比值并进行统计学分析。结果:恶性淋巴结Cho/Cr比值明显高于良性淋巴结节组,差异均具有显著性意义(P<0.01)。与良性结节组相比,恶性肿瘤组织的Cho、Cr峰都明显升高。结论:颈部良、恶性淋巴结氢质子波谱表现明显不同,氢质子波谱对颈部淋巴结的诊断与鉴别具有较高价值。更多还原

【Abstract】 Objective:To investigate the proton magnetic resonance spectroscopy(~1H MRS) features of benign and malignant cervical part lymph node in human.Methods:42 cases were included in the study in which there were 20 cases in benigntumor group and 22 cases in malignant tumor group respectively.The ~1H MRS features of all 42 cases wereanalyzed and the correlation study between in vivo ~1H MRS findings and that of in vitro ~1H MRS was performed.Cho/Cr was calculated on workstation and a statistic test was done.Results:The Cho/Cr、Cho、Cr value in the malignant tumor was larger than in the benign tumor,to benign tumor group.Conclusion:The benign and malignant cervical part lymph node in human showed great difference in ~1H MRS.In vivo ~1H MRS findings demonstrated great consistence with that of in vitro ~1H MRS.In vivo ~1H MRS has high application value in the differentiation diagnosis of cervical part lymph node.更多还原
