摘要
目的:探讨3.0TMR在早期前列腺癌诊断中的价值。方法:回顾性分析经手术病理和穿刺活检证实的12例早期前列腺癌患者的常规序列、DWI及动态增强扫描表现。结果:12例早期前列腺癌患者中,病变均位于包膜内。T2WI抑脂像8例表现为T2WI外周带内异常低信号区,4例表现为中央带稍高信号,DWI序列10例呈高信号,2例等信号。LAVA多期动态增强扫描8例病灶于动脉期明显强化,平衡期为低信号,3例呈持续渐进性强化,1例动脉期强化不明显。结论:3.0TMR的常规T2WI序列、DWI及动态增强扫描在早期前列腺癌诊断中具有特征性表现,联合应用具有明确的诊断价值。
Objective:To study the early diagnostic value of 3.0T MR in prostatic cancer.Methods:To analyse the MR features in 12 cases of early prostatic cancer confirmed by surgery pathology,and needle biopsy.Conventional sequence,DWI and dynamic contrast enhanced scanning were performed.Results:The lesions of the 12 early prostatic cancer cases were all located in the capsule,T2WI fat suppression showed abnormal low signal within the peripheral zone in 8 cases,the other 4 cases showed slightly higher signal in the central zone,DWI sequence in 10 cases showed high signal,2 cases showed isointense signals.LAVA multi-phase dynamic contrast-enhanced scans showed the lesions were obviously enhanced in the arterial phase,low signal in the balance period,in 8 cases 3 cases were continually and progressively enhanced;one case was not obviously enhanced in the arterial phase.Conclusion:3.0T MR conventional T2WI sequences,DWI and dynamic contrastenhanced imaging have characteristic MR features and important diagnostic value for early prostatic cancer.
