概括
一个新的双参数超声波 (BU) 评分系统有效检测临床显著的前列腺癌 (csPCa),为多参数MRI提供了有价值的替代方案. 这种超声波方法有助于风险评估和诊断.
科学领域:
- 放射学 放射学是一门学科.
- 在瘤学瘤学.
- 医疗成像医学成像
背景情况:
- 超声波为前列腺癌检测和活检指导提供了优势.
- 需要使用多参数超声波特征进行全面的定量评估模型.
- 目前的方法缺乏标准化的评分系统,用于风险评估和临床显著的前列腺癌 (csPCa) 检测.
研究的目的:
- 开发一个双参数超声波 (BU) 评分系统,用于前列腺癌 (PCa) 风险评估.
- 评估BU评分系统在检测csPCa.的有效性.
- 将BU的诊断性能与多参数磁共振成像 (mpMRI) 进行比较.
主要方法:
- 在活检前接受BU和mpMRI的392名患者 (培训组) 和166名患者 (验证组) 的回顾性分析.
- 开发一个非增强型双参极超声波 (NEBU) 评分系统和一个包含对比剂到达时间的双参极超声波 (BUS) 评分系统.
- 使用曲线下的面积 (AUC) 与mpMRI的诊断性能的比较,使用活检 (csPCa的格莱森得分≥3+4) 作为黄金标准.
主要成果:
- 在训练和验证组中,NEBU评分系统和BUS的诊断性能与mpMRI的诊断性能相当.
- 在训练组中,NEBU,BUS和mpMRI的AUC分别为0.86,0.86和0.86.
- 验证组中的AUC为0.89 (NEBU),0.90 (BUS) 和0.88 (mpMRI),表明类似的疗效.
结论:
- 开发的BUS是有效和有价值的诊断csPCa,与mpMRI相比较.
- 在特定的临床情况下,NEBU评分系统可以作为替代方案.
- 这些发现支持了高级超声波技术在前列腺癌诊断中的实用性.

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

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,...
