概括

胺质子转移加权成像 (APTWI) 在区分良性和恶性乳腺病变方面显示出前景. 这种技术可能成为动态对比增强 (DCE) 磁力共振成像用于乳腺瘤诊断的有价值的替代品.

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:

胺基质子转移加权成像 (APTWI) 已因其在区分瘤类型方面的潜力而得到认可.
APTWI越来越多地用于乳腺瘤研究.
没有先前的研究直接比较APTWI和动态对比增强 (DCE) MRI,以区分良性和恶性乳腺病变.

研究的目的:

研究APTWI和DCE-MRI在区分良性和恶性乳腺病变中的有效性.
为了比较APTWI和DCE-MRI的诊断性能.
探索APT值与瘤特征之间的相关性.

主要方法:

在40名患有42个乳腺病变的患者身上进行了APTWI.
根据组织学,病变被分类为恶性 (n=28) 或良性 (n=14).
分析了图像特征 (APT,ADC,TIC),ROC曲线量化了诊断性能. 斯皮尔曼的相关性检查了与受体状态和等级的关系.

主要成果:

APT和ADC值显示了观察者之间的强烈一致.
与良性病变 (2.01 ± 0.51) 相比,恶性病变的APT值显著更高 (3.18 ± 1.07).
结合DCE + APTWI实现了曲线下的最高面积 (0.936),优于单个方法.

结论:

APTWI是区分良性和恶性乳腺病变的一个有前途的工具.
在乳腺损伤评估中,APTWI可能成为未来DCE检查的替代品.

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...
