摘要
目的：探讨3.0T MR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：3.0T MR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。
Abstract
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 iso-intense 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 contrast-enhanced imaging have characteristic MR features and important diagnostic value for early prostatic cancer.
