摘要 目的探讨基于体素内不相干运动(IVIM)理论MRDWI技术在鼻咽癌(NPC)应用的可行性,进一步探讨真实扩散系数(D值)、灌注相关扩散系数(D。值)及灌注分数(f值)在首发鼻咽癌的诊断价值。方法选择2011年12月至2013年1月临床怀疑鼻咽癌患者40例,男26例、女14例,中位年龄52岁。患者均行3.0TMR扫描,IVIMDWI采用13个b值(0、10、20、30、50、80、100、150、200、300、400、600、800s/mm2)。患者MR检查后0~11d(平均间隔3d)均行鼻咽部活检;根据不同病理结果分为2组,A组为NPC组(男17例、女9例,中位年龄54岁),B组为鼻咽慢性增生性炎症(NPH)组(男9例、女5例,中位年龄35岁)。IVIM参数值D值、D*值及f值的比较采用非参数Mann—Whitney检验法。结果40例中完成IVIMDWI的患者共36例(其中,A组26例中完成24例,B组14例中完成12例)。A组D值为(0.70±0.13)×10^-3 mm2/s,和B组(0.78±0.05)×10^-3 mm2/s相比,差异有统计学意义(U=2.05,P〈0.05)。A组的f值为(16.25±1.46)%,B组为(26.20±3.90)%,差异有统计学意义(U=11.16,P〈0.01);而D*值A组为(161.8±23.56)×10^-3mm2/s,B组为(55.28±17.05)×10^-3mm^2/s,A组较B组显著增高(U=13.90,P〈0.01)。结论IVIM DWI技术在鼻咽癌的应用是切实可行的,不同D值对鼻咽癌及鼻咽部慢性炎症具有一定的鉴别价值,D*值在鼻咽部良恶性疾病鉴别诊断方面具有潜在的重要价值。 Objective To investigate the feasibility of diffusion-weighted (DWI) MRI on basis of the intravoxel incoherent motion (IVIM) in nasopharyngeal carcinoma (NPC) , and the diagnostic value of pure molecular diffusion coefficient( D), perfusion-related diffusion coefficient( D * ) and perfusion fraction (f) in first onset NPC. Methods From December 2011 to January 2013, 40 consecutive patients (26 men, 14 women; median age, 52 years) with suspected NPC were examined on a 3.0 T MR scanner. DW imaging was performed by using a single-shot echo-planar sequence with 13 b-values (0, 10, 20, 30, 50, 80, 100, 150,200,300,400,600,800 s/mm2 ). MR imaging was compared with endoscopy and biopsy for the detection of NPC. Mean interval time between MR imaging examination and subsequent nasopharyngeal biopsy was 3 days (range, 0-11 days). The subjects were divided into 2 groups according to the pathological results, group A was subjects with NPC (17 men, 9 women; median age, 35 ) and group B was ones with nasopharyngeal chronic hyperplastic inflammation(NPH) (9 men, 5 women; median age ,35 ). The D, D * and f were measured and compared in patients with first onset NPC and nasopharyngeal hyperplasia (Mann-Whitney test). Results IVIM DWI was successful in 24/26 with NPC and 12/14 with NPH. D value was significantly lower in A group compared with B group [ mean, ( 0. 70 ± 0. 13 )×10^-3 mm2/s vs (0.78 ±0.05)×10^-3 mm2/s; U=2.05, P〈 0.05], as was f value[mean, (16.25 ± 1.46) % vs (26. 20 ± 3.90)% ; U = 11.16, P 〈 0.01 ]. However, D * value was significantly higher in Agroupas compared with B groupromean, (161.8 ±23.56) ×10^-3 mm2/s vs (55.28 ± 17.05)×10^-3mm2/s; U = 13.90, P 〈 0.01 ]. Conclusions IVIM DWI is a feasible technique for investigating first onset NPC and D value has a certain value in differentiating NPC and NPH. D * value has an important potential value in distinguishing benign and malignant NPC.
