摘要：
当怀疑前列腺癌时，多参数 MRI 是最佳的初步检查，其排除和排除临床重大疾病的能力依赖于高质量的解剖和功能图像。实现一致的高质量采集的途径包括细致的患者准备、扫描仪设置、优化的脉冲序列、人员培训和人工智能系统。这些干预措施对最终图像的影响需要量化。前列腺成像质量 (PI-QUAL) 评分系统是第一个标准化量化方法，通过将图像质量与 MRI 癌症检测能力联系起来，证明了临床获益的潜力。我们推出 PI-QUAL (PI-QUAL v2) 的更新版本，适用于使用或不使用静脉造影剂进行的前列腺 MRI，使用简化的 3 点量表，重点关注关键技术和定性图像参数。临床相关性声明：高图像质量对于前列腺 MRI 至关重要，PI-QUAL 评分的更新版本 (PI-QUAL v2) 旨在解决版本 1 的局限性。它现在适用于多参数 MRI 和无静脉注射 MRI造影剂。要点：高质量图像对于使用 MRI 进行前列腺癌诊断和治疗至关重要。 PI-QUAL v2 简化了图像评估，并将其适用性扩展到无需造影剂的前列腺 MRI。 PI-QUAL v2 专注于关键技术和定性图像参数，并强调 T2-WI 和 DWI。© 2024。作者。
Multiparametric MRI is the optimal primary investigation when prostate cancer is suspected, and its ability to rule in and rule out clinically significant disease relies on high-quality anatomical and functional images. Avenues for achieving consistent high-quality acquisitions include meticulous patient preparation, scanner setup, optimised pulse sequences, personnel training, and artificial intelligence systems. The impact of these interventions on the final images needs to be quantified. The prostate imaging quality (PI-QUAL) scoring system was the first standardised quantification method that demonstrated the potential for clinical benefit by relating image quality to cancer detection ability by MRI. We present the updated version of PI-QUAL (PI-QUAL v2) which applies to prostate MRI performed with or without intravenous contrast medium using a simplified 3-point scale focused on critical technical and qualitative image parameters. CLINICAL RELEVANCE STATEMENT: High image quality is crucial for prostate MRI, and the updated version of the PI-QUAL score (PI-QUAL v2) aims to address the limitations of version 1. It is now applicable to both multiparametric MRI and MRI without intravenous contrast medium. KEY POINTS: High-quality images are essential for prostate cancer diagnosis and management using MRI. PI-QUAL v2 simplifies image assessment and expands its applicability to prostate MRI without contrast medium. PI-QUAL v2 focuses on critical technical and qualitative image parameters and emphasises T2-WI and DWI.© 2024. The Author(s).
