摘要
目的 :探讨3D动脉自旋标记灌注成像技术(3D arterial spin labeling,3D-ASL)、肿瘤血流(tumor blood flow,TBF)与舌部肿物组织病理学特征之间的相关性。方法:前瞻性分析2019年12月—2021年12月上海交通大学医学院附属第九人民医院临床拟诊为舌部肿物的患者55例,术前均行颌面部常规MRI平扫、3D-ASL、扩散加权成像(diffusion-weighted imaging,DWI)和动态增强(dynamic contrast-enhanced,DCE)序列扫描。计算病灶的TBF,术后组织切片用CD34及Ki67染色以评估微血管密度(microvessel density,MVD)。利用SPSS 26.0软件中的Mann-Whitney U检验分析不同疾病间的TBF,以及TBF和MVD的相关性。结果:舌异位甲状腺(ectopic thyroid,ET)在ASL的TBF伪彩图上均表现为整体红色的高灌注区(100%),且高灌注的面积最大(100%)。舌鳞状细胞癌(squamous cell carcinoma,SCC)早期高灌注比例较高(13例,13/15,86.7%)。测量瘤体血流最大区域TBFmax、TBFmean、ADC值之间的差异具有统计学意义(P<0.05)。所有肿瘤中MVD与TBFmean、TBFmax呈强正相关(rs=0.89、0.93,R2=0.70、0.84,P<0.01)。结论:3D-ASL可无创评估舌部肿瘤血流,利于区别良、恶性肿瘤。SCC分级越高,高灌注出现越少,可反映出受肿瘤侵犯的程度。
PURPOSE:To investigate the correlation between 3D arterial spin labeling(3D-ASL),tumor blood flow(TBF)and histopathological features of tongue masses.METHODS:A prospective analysis was performed in 55 patients with clinically probable tongue masses in Shanghai Ninth People’s Hospital,Shanghai Jiao Tong University School of Medicine from December 2019 to December 2021,and all of them underwent conventional maxillofacial MRI scanning,3D-ASL,diffusion-weighted imaging(DWI)and dynamic contrast-enhanced(DCE)sequence scanning before surgery.TBF of lesions was calculated,and postoperative tissue sections were stained with CD34 and Ki67 to assess microvessel density(MVD).Mann-Whitney U test was used to compare and analyze TBF between different diseases,as well as the correlation between TBF and MVD with SPSS 26.0 software package.RESULTS:Ectopic thyroid(ET)showed an overall red hyperperfusion area(100%)on the TBF pseudocolor map of ASL,and the hyperperfusion area was the largest(100%).The proportion of hyperperfusion in early squamous cell carcinoma(SCC)was high(13 cases,13/15,86.7%).The difference between TBFmax,TBFmean,and ADC values in the largest region of tumor blood flow was statistically significant(P<0.05).MVD was strongly positively correlated with TBFmean and TBFmax in all tumors(rs=0.89,0.93,R2=0.70,0.84,P<0.01).CONCLUSIONS:3D-ASL can noninvasively assess tongue tumor blood flow and help distinguish benign and malignant tumors.The higher the SCC grade,the less hyperperfusion occurs,which reflects the degree of tumor invasion.
