通过高率对比增强超声波对固体瘤的定性和定量分析
概括
高率对比增强超声波 (H-CEUS) 与传统对比增强超声波 (C-CEUS) 相比,提供了更清晰的瘤可视化. 定量分析显示了明显的时间强度曲线参数,表明H-CEUS提供了固体质的优越表征.
科学领域:
- 医疗成像医学成像
- 腎臟病學 (nephrology) 是一種醫學.
- 在瘤学瘤学.
背景情况:
- 固体质需要准确的特征,用于诊断和治疗规划.
- 传统的对比增强超声波 (C-CEUS) 是对脏瘤的标准成像方法.
- 高率对比增强超声波 (H-CEUS) 在成像分辨率和时间动态方面提供了潜在的进步.
研究的目的:
- 在固体瘤中比较高率对比增强超声波 (H-CEUS) 与常规对比增强超声波 (C-CEUS) 的定性和定量成像特征.
- 评估H-CEUS在区分良性和恶性质中的诊断性能.
主要方法:
- 追溯分析75名患有89个质的患者,接受常规超声波,C-CEUS和H-CEUS.
- 对病变特征和对比度增强模式 (洗,填充) 的定性评估.
- 定量分析时间强度曲线 (TIC) 参数,包括峰值强度 (PI),减速时间 (DT) /2,曲线下的面积 (AUC) 和平均过渡时间 (MTT).
主要成果:
- 良性和恶性群体之间的性别,回声性和颜色多普勒血流成像 (CDFI) 显著差异.
- 与恶性瘤中的C-CEUS相比,H-CEUS在冲洗模式和填充方向上表现出显著的差异.
- 定量分析显示,在良性和恶性两组中,H-CEUS与C-CEUS相比,H-CEUS的PI,DT/2,AUC和MTT显著降低 (p < 0.001).
- 在恶性质群体的H-CEUS中,上升曲线 (AS) 的上升斜率显著更高 (p=0.048).
结论:
- 与C-CEUS相比,H-CEUS在瘤中提供了更清晰的内部增强和洗动态的可视化.
- 定量TIC参数 (PI,DT/2,AUC,MTT) 与H-CEUS显著较低,而AS在恶性质群中较高.
- 定性和定量分析都表明H-CEUS提供了比C-CEUS更好的固体质的表征.

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,...

Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.
