In the last decade, technical advances in magnetic resonance imaging (MRI) have made it the technique of choice in the overall management of patients with suspected or confirmed prostate cancer. MR makes it possible to acquire information about morphology and function in the same examination by using techniques like spectroscopy, diffusion, and dynamic sequences with intravenous contrast material administration. Moreover, MRI enables both focused study of the prostate gland and of regional and/or whole-body involvement, depending on the clinical indications, in less than an hour. The main clinical indications for MRI of the prostate are a) staging local, regional, and/or remote disease; b) detecting prostate cancer or guiding prostate biopsy in cases of clinical suspicion or negative findings in previous biopsy specimens; and c) monitoring the response to treatment. It is important to know the different protocols with specific MRI sequences for the prostate, depending on the different clinical indications, to ensure that they are performed and interpreted correctly. This article provides up-to-date information about the use of MRI for the study of the prostate to show how the morphological and functional information can be used in clinical practice.
在过去十年中，磁共振成像（MRI）技术的进步使其成为疑似或确诊前列腺癌患者综合管理中的首选技术。通过使用光谱分析、扩散成像以及静脉注射造影剂的动态序列等技术，MRI能够在同一次检查中获取有关形态和功能的信息。此外，根据临床指征，MRI能够在不到一小时的时间内对前列腺进行重点研究，并评估局部和/或全身受累情况。前列腺MRI的主要临床指征包括：a）对局部、区域和/或远处疾病进行分期；b）在临床怀疑或先前活检标本结果为阴性的情况下，检测前列腺癌或指导前列腺活检；c）监测治疗反应。了解针对前列腺的不同MRI序列的特定方案非常重要，这取决于不同的临床指征，以确保检查的正确实施和解读。本文提供了有关MRI用于前列腺研究的最新信息，以展示形态学和功能信息如何应用于临床实践。
