Acquiring multiparametric magnetic resonance images of the prostate is not a simple "push-button" approach.
To show how image acquisition of prostate multiparametric Magnetic Resonance Imaging (mpMRI) can be optimized.
DESIGN, SETTING, AND PARTICIPANTS: Image protocols, magnetic field strength choice, and the use of receiver coils are discussed. In addition, patient preparation and the recognition, prevention, and mitigation of artifacts are evaluated.
Based on expert prostate MRI technologists (MRI radiographers) opinion, the optimal protocol is reviewed, and potential artifacts are determined.
The entire acquisition process is presented from initial patient preparation until the end of the imaging. The choice of the used equipment, pulse sequences, and prevention of patient- and imaging-related artifacts are presented. This will be shown in individual patients.
Although the Prostate Imaging Reporting and Data System guidelines (2012 and 2016) describe minimal and optimal acquisition protocols for prostate mpMRI, these standards are not always met in daily practice. A major challenge in mpMRI is to obtain high image quality and reduce its variability for radiologic interpretations. A summary of evidence and guidelines for the acquisition of mpMRI of the prostate can set a basic guideline to reduce these variabilities.
This article and an accompanying video can be used as a guide by MRI technologists (MRI radiographers) to improve their image acquisitions by optimizing protocols, magnetic field strength choice, and use of receiver coils. We also discuss patient preparation and the recognition, prevention, and mitigation of artifacts.
In this first surgery-in-motion contribution, we will show how optimized image acquisition is performed to detect prostate cancer. Both MRI-dependent and patient related factors are discussed.
获取前列腺的多参数磁共振图像并不是一个简单的“一键式”方法。
展示如何优化前列腺多参数磁共振成像（mpMRI）的图像采集。
设计、设置和参与者：讨论了图像协议、磁场强度选择以及接收线圈的使用。此外，还评估了患者准备以及伪影的识别、预防和缓解。
根据专家前列腺 MRI 技师（MRI 放射技师）的意见，对最佳方案进行了回顾，并确定了潜在的伪影。
从最初的患者准备到成像结束，介绍了整个采集过程。展示了所使用设备、脉冲序列以及患者和成像相关伪影的预防选择。这将在个别患者中进行展示。
尽管前列腺成像报告和数据系统指南（2012 年和 2016 年）描述了前列腺 mpMRI 的最小和最佳采集方案，但这些标准在日常实践中并不总是得到满足。mpMRI 的主要挑战是获得高质量的图像并降低其放射学解释的可变性。前列腺 mpMRI 采集的证据和指南摘要可以为减少这些可变性设定一个基本指南。
本文和配套视频可作为 MRI 技师（MRI 放射技师）的指南，通过优化方案、磁场强度选择和接收线圈的使用来改进图像采集。我们还讨论了患者准备以及伪影的识别、预防和缓解。
在这项首次手术中动态贡献中，我们将展示如何进行优化的图像采集以检测前列腺癌。讨论了 MRI 相关和患者相关的因素。
