| 目的探讨磁共振肝脏快速容积采集(LAVA)多时相动态增强技术结合扩散加权成像(DWI)在评价前列腺病变性质上的应用。方法67例经组织病理学及随访证实的前列腺疾病患者,其中前列腺癌(PCa)19例,前列腺良性病变(BPH)48例,行LAVA多时相动态增强及DWI扫描,测量并计算其表观扩散系数(ADC)值,经2名有经验的医师进行双盲阅片,比较T-SI曲线及其结合ADC值对PCa、BPH的定性诊断准确率。结果T-SI曲线对PCa、BPH 的定性诊断准确率分别为57.9%、72.9%,T-SI 曲线结合ADC值对PCa、BPH的定性诊断准确率分别为73.7%、87.5%。 结论LAVA多时相动态增强技术结合ADC值对前列腺良恶性病变的鉴别具有重要应用价值。 |

| Abstract: |
| ObjectiveTo explore the value of liver acquisition with volume acceleration (LAVA) multi-phase dynamic enhanced technique combined with magnetic resonance diffusion weighted imaging(ＤＷＩ) in evaluating prostate lesions. MethodsTotally 67 prostate disease patients confirmed by histopathology and follow-up were included in the present study. The patients included 19 with prostate cancer (PCa) and 48 with benign prostate hyperplasia (BPH). LAVA multi-temporal enhancement and DWI scanning were performed, and the values of apparent diffusion coefficient (ADC) were calculated. Two experienced radiologists evaluated the results in a double-blinded manner; the qualitative diagnosis accuracy rates of the T-SI curves alone or in combination with ADC for PCa and BPH were compared. ResultsThe accuracy rates of T-SI curve alone for qualitative diagnosis of PCa, BPH were 57.9% and 72.8%, and those of T-SI curve combined with ADC value were 73.7% and 87.5%, respectively. ConclusionLAVA multi-phase dynamic enhanced technique combined with ADC is of great value for differential diagnosis of benign and malignant prostate lesions. |
