The benefits and drawbacks of the dynamic contrast-enhanced MRI sequence for prostate cancer diagnosis are increasingly being recognized, with many centers adopting the biparametric (bp) MRI approach as the default initial approach. The abandonment of the routine use of contrast medium requires an assessment of the loss of diagnostic power against the gains in operational logistics, costs, time, capacity, and side effects. It is the balance of these factors weighted against the clinical priorities of patients that determines which patient groups can safely avoid dynamic contrast enhancement. Although systematic reviews and individual studies are broadly supportive of the bpMRI approach, the pathway impacts for men with suspected cancer using the bpMRI approach are still not well documented for clinical practice. Robust prospectively acquired data for bpMRI regarding biopsy avoidance, detection of clinically significant and insignificant cancers, and for increasing the precision of tumor grade and volume are needed. There is a requirement for prospective, randomized, or blinded head-to-head, multicenter studies, addressing the noninferiority of biopsy yields prompted by bpMRI and multiparametric MRI approaches. These studies should more precisely define patient groups where the benefits and harms of contrast enhancement are aligned to their clinical priorities. Only then can we be confident in recommending bpMRI as an initial diagnostic approach for prostate cancer diagnosis. Level of Evidence 1 Technical Efficacy Stage 5.
动态对比增强磁共振成像(MRI)序列在前列腺癌诊断中的利弊日益受到认可,许多中心已将双参数(bp)MRI方法作为默认的初始方法。放弃常规使用造影剂需要评估诊断能力的损失与操作流程、成本、时间、容量和副作用方面的收益。正是这些因素与患者临床优先级的权衡,决定了哪些患者群体可以安全地避免动态对比增强。尽管系统评价和个别研究广泛支持bpMRI方法,但对于临床实践中使用bpMRI方法的疑似癌症男性患者的路径影响仍未得到充分记录。需要关于bpMRI在避免活检、检测临床显著和不显著癌症以及提高肿瘤分级和体积精度方面的可靠前瞻性数据。需要进行前瞻性、随机或盲法的头对头多中心研究,以探讨bpMRI和多参数MRI方法在活检阳性率方面的非劣效性。这些研究应更精确地界定造影剂增强的利弊与临床优先级相匹配的患者群体。只有这样,我们才能有信心推荐bpMRI作为前列腺癌诊断的初始诊断方法。证据水平1技术疗效阶段5。
