摘　　要：目的探讨MRI多参数在鉴别嗅神经母细胞瘤(olfactory neuroblastoma,ONB)和鼻腔鼻窦弥漫大B细胞淋巴瘤(diffusion large B cell lymphoma,DLBCL)中的价值。方法34例鼻腔鼻窦ONB和29例DLBCL患者治疗前行MRI检查。MRI评估指标包括常规征像和半定量参数。连续变量比较采用独立样本t检验或秩和检验,分类变量比较采用χ^(2)检验。二元Logistic回归用于识别最有诊断能力的MRI指标。结果ONB T2WI呈等稍高信号,累及嗅裂,易形成颅内肿块(P=0.004);DLBCL T2WI呈等略低信号(P<0.001),常累及上颌窦、眼眶(P<0.001,P=0.024)。ONB的鼻甲外移、边缘分叶征较DLBCL多见(P=0.001,P=0.004)。ONB的ADC_(ave)值更高(P<0.001),CI_(max)、WR更大(P<0.001、P=0.011),TTP小(P=0.003),TIC曲线流出型更多(P=0.022)。Logistic回归显示部位(累及嗅裂或上颌窦)、T2WI信号、ADC0.82值及以TTP52是鉴别ONB和DLBCL的独立影响因素。结论MRI的多参数联合有助于鉴别鼻腔鼻窦ONB和DLBCL。OBJECTIVE To investigate the value of magnetic resonance imaging(MRI)parameters in differentiation between olfactory neuroblastoma(ONB)and sinonasal diffusion large B cell lymphoma(DLBCL).METHODS Pathologyproven 34 ONB patients and 29 DLBCL patients with MRI examinations before treatment were included.The conventional MRI features and semi-quantitative parameters of two groups were documented and analysis.Statistical analysis between the two groups were performed.The independent sample t-test and was used for continuous variables in normal distribution,Mann-Whitney U test was used for non-normal distribution.The frequency of categorical variables were compared by Chisquare test.Logistic regression analysis was done to identify the most predictive MRI features for differentiation.RESULTS ONB often located in the nasal cavity olfactory recess and ethmoid sinus,characterized by intracranial extension through the cribriform plate,forming a‘dumbbell’shape mass(P=0.004).DLBCL more often located in paranasal sinus,orbits(P<0.001,P=0.024).T2WI signal intensity of ONB were higher than DLBCL(P<0.001).ONB showed more signs of outward turbinate and lobulation(P=0.001,P=0.004).ADC_(ave)of ONB was obviously higher than DLBCL(P<0.001).On DCE-MRI,ONB showed higher CI_(max),WR(P<0.001,P=0.011),lower TTP than DLBCL(P=0.003).ONB presented more wash-out type TIC curve(P=0.022).Logistic regression analysis demonstrated that tumor location(olfactory cleft or maxillary sinus),T2WI intensity,ADC_(ave)with cutoff value of 0.82×10^(-3)mm^(2)/s and TTP with cut off value of 52 seconds were the most predictive MRI features for differentiation.CONCLUSION The multiple MRI conventional and functional parameters are helpful in differentiating ONB from DLBCL.
