概括

前列腺成像报告和数据系统 (PI-RADS) 在两个MRI扫描中显示病变识别的一致性. 前列腺MRI扫描之间的6周间隔没有显著影响活检结果.

科学领域:

放射学和泌尿病学
癌症学
医学成像

背景情况:

前列腺癌的诊断依赖于多参数磁共振成像 (mpMRI) 和前列腺成像报告和数据系统 (PI-RADS).
在PI-RADS评分的一致性对于精确的病变识别和随后的活检规划至关重要.
图像检查方案的变化或扫描之间的时间间隔可能会影响诊断可靠性.

研究的目的:

评估前列腺成像报告和数据系统 (PI-RADS) 在前列腺癌中病变识别的一致性.
评估两次多参数磁共振成像 (mpMRI) 扫描之间的6周间隔对活检结果的影响.
分析PI-RADS得分和组织学发现在大量的第三级护理环境中的相关性.

主要方法:

在2018年至2022年间进行两次前列腺mpMRI扫描的111名患者的实际数据的回顾性分析.
在不同机构进行扫描,平均间隔42天.
在第二次MRI后7天进行了MRI融合活检.

主要成果:

在室内MRI上,PI- RADS V和IV是指数病变的最常见分类 (33. 3%和49. 5%).
癌症检测率因PI- RADS得分而异,PI- RADS V显示了最高的检测率 (91. 9%).
在64. 9%的向病变和57. 7%的随机活检中发现了恶性组织学;活检计划对51. 4%的患者进行了调整.

结论:

连续进行前列腺核磁共振扫描的6周间隔没有显著影响活检结果的质量或可靠性.
PI-RADS分类仍然是预测癌症检测率的一个关键因素.
即使在成像研究之间有适度的时间间隔,也可以实现一致的病变识别和准确的活检计划.

Imaging Studies IV: Magnetic Resonance Imaging

Introduction:Magnetic Resonance Imaging, or MRI, can include a specialized imaging technique of the urinary system known as Magnetic Resonance Urography (MRU). This radiation-free technique uses strong magnetic fields and radio waves to produce detailed images with the help of a computer. MRU is particularly effective for visualizing fluid-filled structures like the kidneys, ureters, and bladder.Applications of MRI in the Genitourinary SystemKidneys and Ureters: MRI detects tumors, cysts,...

Magnetic Resonance Imaging

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...
