【摘要】：目的研究前列腺核磁共振成像(MRI)联合前列腺特异性抗原密度(PSAD)对前列腺癌(PCa)和前列腺增生(BPH)的诊断价值。方法 81例有穿刺活检或手术病理结果的前列腺病例,经穿刺或手术病理确诊28例为前列腺癌患者,53例为前列腺增生患者,回顾分析其资料,收集患者MRI的诊断结果、前列腺特异性抗原(PSA)数值及测量前列腺体积,结合PSA数值及前列腺体积,计算出PSAD,分别分析前列腺MRI及PSAD诊断结果及当MRI诊断不明时,联合PSAD的诊断结果。结果 MRI对前列腺癌和前列腺增生的诊断准确率分别为90.0%(18/20)、96.0%(24/25);PSAD对前列腺癌和前列腺增生的诊断准确率分别为68.0%(17/25)、80.4%(45/56);当MRI诊断不明确时,联合PSAD,前列腺癌阴性诊断率为78.6%(22/28)。结论联合MRI和PSAD可以明显提高前列腺癌和前列腺增生的诊断水平。
[Abstract]:Objective to study the diagnostic value of prostatic magnetic resonance imaging (MRI) combined with prostate specific antigen density (PSAD) in the diagnosis of prostatic carcinoma (PCA) and prostatic hyperplasia (BPH). There were 28 cases of prostate cancer diagnosed by puncture or operation and pathology. The data of 28 patients with prostate cancer and 53 patients with prostatic hyperplasia were analyzed retrospectively, the diagnostic results of MRI, the value of prostate specific antigen (PSA) and the volume of prostate were collected. Combined with PSA value and prostate volume, PSAD was calculated, and the diagnostic results of MRI and PSAD were analyzed, respectively, and when the diagnosis of MRI was unknown, Results the diagnostic accuracy of MRI for prostate cancer and prostatic hyperplasia was 90.0 / 20 / 20 / 96. 0, respectively. The diagnostic accuracy of MRI for prostate cancer and prostatic hyperplasia was 68.0 / 25 / 80.4 / 4556, respectively. When the diagnosis of MRI was not clear, In combination with PSAD, the negative diagnosis rate of prostate cancer was 78.6 / 28%. Conclusion the combination of MRI and PSAD can significantly improve the diagnostic level of prostate cancer and prostatic hyperplasia.
