Abstract

Currently there is a lot of interest in the use of a “biparametric” or “abbreviated” prostate MR protocol, which usually refers to removal of the dynamic contrast-enhanced (DCE) MRI, in the detection of clinically significant prostate cancer. In this article we describe the benefits of DCE as part of the PI-RADS lexicon, with particular reference to its role in PI-RADS V2 category 3 peripheral zone lesions. We also discuss the benefits of triplanar T2-weighted images, and finally discuss how a mpMRI protocol is of benefit in prostate cancer staging, in evaluating for local disease recurrence, and as a biomarker for neoadjuvant therapy response.

反对使用缩写或双参数前列腺MRI协议的争论

摘要

当前，对“双参数”或“缩写”前列腺MR协议的使用引起了很多兴趣，该协议通常是指在临床上重要的前列腺癌的检测中去除动态对比增强（DCE）MRI。在本文中，我们描述了DCE作为PI-RADS词典的一部分的优势，特别是其在PI-RADS V2第3类外围区域病变中的作用。我们还讨论了三瓣T2加权图像的好处，最后讨论了mpMRI协议在前列腺癌分期中，在评估局部疾病复发以及作为新辅助治疗反应的生物标志物方面如何有益。
