Abstract

THE PURPOSE

Assessing the accuracy of multi parametric magnetic resonance (mp-MRI) after application of PI-RADS V2 for diagnosis of prostate cancer as comparison to pathological results of trans rectal ultra-sound (TRUS) guided biopsy.

PATIENTS AND METHODS

138 prostatic lesions in 23 patients were retrospectively assessed and analyzed with Trans rectal ultra-sound (TRUS) guided biopsy results. Those patients underwent multi parametric magnetic resonance (mp-MRI) with application of PI-RADS V2 reporting system. The sensitivity, specificity, validity, negative predictive value and positive predictive value were calculated for PI-RADS V2 reporting system compared to biopsy-proven pathological results.

RESULTS

92 out of 138 lesions were positive for Peripheral zone cancer prostate. PI-RADS V2 reporting system proved 88.04% sensitive & 93.4% specific for diagnosis of prostate cancer with negative predictive value & positive predictive value of 100%.

CONCLUSION

Our results proved that mp-MRI of prostate using PI-RADS v2 scoring system had high sensitivity and specificity in diagnosis of prostate cancer and PI-RADS V2 scoring system using mp-MRI is recommended as a non-invasive diagnostic tool compared to TRUS guided biopsy.

摘要

目的

评估应用PI-RADS V2后多参数磁共振成像（mp-MRI）对前列腺癌诊断的准确性，并与经直肠超声（TRUS）引导活检的病理结果进行比较。

患者与方法

回顾性评估并分析23例患者的138个前列腺病变及TRUS引导活检结果。这些患者接受了应用PI-RADS V2报告系统的多参数磁共振成像（mp-MRI）检查。将PI-RADS V2报告系统与活检证实的病理结果进行比较，计算其敏感性、特异性、有效性、阴性预测值和阳性预测值。

结果

138个病变中有92个外周带前列腺癌呈阳性。PI-RADS V2报告系统对前列腺癌诊断的敏感性为88.04%，特异性为93.4%，阴性预测值和阳性预测值均为100%。

结论

我们的结果证明，使用PI-RADS v2评分系统的前列腺mp-MRI在前列腺癌诊断中具有高敏感性和特异性，与TRUS引导活检相比，推荐将使用mp-MRI的PI-RADS V2评分系统作为一种非侵入性诊断工具。
