磁共振弥散加权成像DWI及动态增强扫描诊断前列腺癌的价值探讨

Magnetic resonance diffusion weighted imaging DWI and dynamic contrast-enhanced scan in diagnosis of prostate cancer

目的 研究分析磁共振弥散加权成像DWI及动态增强扫描对前列腺癌患者的诊断价值.方法 选择我院收治的经病理学检查确诊为前列腺癌的患者40例作为研究对象,对所有患者进行磁共振弥散加权成像DWI检查及动态增强扫描,并与病理学检查结果对比,分析其临床诊断效果.结果 前列腺癌患者的ADC为（0.81±0.09）,最大强化率为（138.98±36.34）,1 min强化率为（132.87±35.35）,2 min强化率为（133.09±41.21）,流出分数为（17.72±7.88）.与病理学检查诊断结果对比,2种检查方法对前列腺癌的检出率差异无统计学意义（P＞0.05）.结论 使用磁共振弥散加权成像DWI及动态增强扫描诊断前列腺癌效果较为理想,与病理学诊断较为接近,可以在临床上推广应用.

Objective To study the value of magnetic resonance diffusion weighted imaging DWI and dynamic contrast-enhanced scan in the diagnosis of patients with prostate cancer.Methods 40 patients diagnosed with prostate cancer were selected from our hospital as study objects.All the patients underwent diffusion weighted magnetic resonance imaging DWI and dynamic contrast-enhanced scanning.The results were compared with pathological results.Its clinical effect was analyed.Results The patients ADC was （0.81 ± 0.09）.The maximum enhancement rate was （138.98 ± 36.34）.The 1 minutes enhancement rate was （132.87 ± 35.35）.The 2 minutes enhancement rate was （133.09 ± 41.21）.The outflow fraction was （17.72 ± 7.88）.There was no statistical difference in diagnosing prostate cancer between these 2 methods（P 〉 0.05）.Conclusions Magnetic resonance diffusion weighted imaging DWI and dynamic contrast-enhanced scan in the diagnosis of patients with prostate cancer is effective.Its diagnostic value is as much the same as pathological diagnosis＆#39;.It should be clinically generalized.
