目的探讨前列腺中央腺体癌的磁共振波谱分析(MRS)及扩散加权成像(DWI)表现,并对误诊病例进行分析。资料与方法回顾性研究术前MR诊断为前列腺中央腺体癌的患者共58例,术后确诊为癌40例、非癌18例,比较两组间的(胆碱+肌酸)/枸橼酸盐(CC/C)值和表观扩散系数(ADC)值。结果中央腺体癌组CC/C值及最小ADC值分别为2.89±1.26、(0.81±0.16)×10-3mm2/s,非癌组CC/C值及最小ADC值分别为1.28±0.59、(1.02±0.18)×10-3mm2/s,中央腺体癌组与非癌组之间的CC/C值及最小ADC值差异均有统计学意义(t值分别为5.994、-3.862,P值均<0.05)。结论 MRS和DWI对于前列腺中央腺体癌的诊断具有一定的价值。
Objective To investigate the MRS and diffusion weighted imaging (DWI) manifestations of central prostate cancer and to analyze the misdiagnosed cases. Materials and Methods Retrospective study of preoperative diagnosis of prostate central gland cancer in patients with a total of 58 patients were diagnosed as 40 cases of cancer, non-cancer in 18 cases, compared between the two groups (choline + creatine) / citron Acid value (CC / C) and apparent diffusion coefficient (ADC) values. Results The CC / C value and minimum ADC value of central gland cancer group were 2.89 ± 1.26 and 0.81 ± 0.16 × 10-3mm2 / s, respectively. The CC / C value and minimum ADC value of non-cancer group were 1.28 ± 0.59 and 1.02 ± 0.18) × 10-3mm2 / s. There were significant differences in CC / C value and minimum ADC value between central gland cancer group and non-cancer group (t = 5.994, -3.862, P = <0.05). Conclusion MRS and DWI have certain value for the diagnosis of central prostate cancer.
