摘要: 目的 探讨多参数磁共振成像对T1高信号间隔与非T1高信号间隔的原发性鼻腔鼻窦黑色素瘤(PSM)的鉴别价值。方法 回顾性分析经病理证实的 PSM 44例,术前均接受常规,DWI 和DCE-MRI检查。通过单因素和多因素Logistic分析评估T1高信号间隔与非T1高信号间隔PSM各MRI参数的差异。结果 44例PSMs 中,T1高信号间隔PSMs 25例,非T1高信号间隔PSMs 19例。两者在多参数MRI中,仅T2低信号间隔,ADC值、达峰时间(Tp)及最大相对增强率(MRER)在单变量分析中差异存在统计学意义(均P<0.05),在多因素Logistic分析中差异均无统计学意义(P均>0.05)。结论 多参数MRI对区分T1高信号间隔与非T1高信号间隔的PSM具有一定的指导价值,但并不能作为区分两者的独立预测指标。

Abstract: Objective To evaluate the diagnostic value of multi-parameter MRI in differential diagnosis of primary sinonasal melanoma(PSM)with high- and non-high-T1 signal septa.Methods Forty-four patients pathologically confirmed with PSMs underwent conventional,DWI and DCE-MRI examinations before operation.Univariate and multivariate Logistic analyses were used to evaluate the differences of MRI parameters between high- and non-high-T1 signal septa in PSMs.Results Among 44 PSMs,25 cases had high T1 signal septa and 19 cases had non-T1 high signal septa.In multi-parameter MRI,only T2 low signal septa,the value of ADC,peak time(TP)and maximum relative enhancement rate(MRER)were significantly different in univariate analysis(P<0.05),but not in multivariate Logistic analysis(P>0.05).Conclusions Multi-parameter MRI has some value in differentiating PSM with high-T1 and non-high-T1 signal septa,but it can not be used as an independent predictor to distinguish them.
