Abstract: [Abstract] Objective To evaluate the feasibility of quantitative DCE-MRI parameters in the differential diagnosis of head and neck squamous cell carcinoma and undifferentiated carcinoma. Methods Forty-two patients with head and neck squamous cell carcinoma (HNSCC) and 53 patients with undifferentiated carcinoma (UC) were enrolled. The mean age was 63±17 years, 45±23 years, and a total of 95 patients were examined with MRI before treatment, and QDCE-MRI quantitative parameters were evaluated to analyze pathological types and MRI parameters (including volume transport constant (Ktrans), reverse reflux rate constant (Kep), extravascular extracellular space (Ve), plasma The relationship between volume fraction (Vp), peak time (TTP), maximum concentration (MAXCon), area under the curve (AUC), and maximum slope (MAXSlope). Results The values of Ktrans, Kep, TTP, MAXSlope of HNSCC were 0.09620±0.3894 min-1, 0.6527±0.2608 min-1, 2.9640±0.8409 min,1.8499±0.7698, The value of Ktrans, Kep, TTP, MAXSlope of HNSCC is 0.1432±0.0527 min-1, 0.8520±0.2166 min-1, 2.1055±0.9605 min, 2.1543±0.8767(mean±SD). The differences of Ktrans, Kep, TTP and MAXSlope between HNSCC group and UC group were statistically significant (P<0.05). Conclusion DCE-MRI quantitative parameters including Ktrans, Kep, TTP, MAXSlope can be used to identify head and neck squamous cell carcinoma and undifferentiated cancer.

摘要: [摘要] 目的 评价定量动态对比增强磁共振成像(DCE-MRI)参数鉴别诊断头颈部鳞癌和未分化癌的可行性。方法 收集42名患有头颈部鳞状癌,53名患有未分化癌的患者,平均年龄分别为63±17岁,45±23岁,总共95名患者在治疗前进行MRI检查,对QDCE-MRI定量参数进行评估,分析病理类型和MRI参数,包括体积转运常数(Ktrans)、反向回流速率常数(Kep)、血管外细胞外间隙体积(Ve)、血浆体积分数(Vp)、达峰时间(TTP)、最大浓度(MAXCon)、曲线下面积(AUC)、最大斜率(MAXSlope)之间的关联。结果 HNSCC组Ktrans,Kep,TTP,MAXSlope值分别为0.09620±0.3894 min-1,0.6527±0.2608 min-1,2.9640±0.8409 min,1.8499±0.7698,UC组患者的Ktrans,Kep,TTP,MAXSlope值分别为0.1432±0.0527 min-1,0.8520±0.2166 min-1,2.1055±0.9605 min,2.1543±0.8767,两组间差异有统计学意义(P<0.05),其余参数无统计学差异。结论 包括Ktrans、Kep、TTP、MAXSlope在内的DCE-MRI定量参数可以用来鉴别头颈鳞癌和未分化癌。
