概括

敏感度加权成像 (SWI) 显示诊断准确度与ADC值相比,用于区分乳腺病变. 结合SWI和ADC可以提高无对比乳房MRI的诊断信心.

科学领域:

放射学放射学是一门学科.
医疗成像医学成像
在瘤学瘤学.

背景情况:

非对比的乳房MRI是一种日益增长的对比增强成像的替代方案.
在没有对比的情况下区分良性病变和恶性病变可能是具有挑战性的.
对改进诊断的替代序列的研究至关重要.

研究的目的:

评估SWI序列在区分良性和恶性乳腺病变的诊断性能.
将SWI的诊断贡献与ADC值进行比较.
评估SWI在非对比性乳腺MRI中的附加值.

主要方法:

对129名经遗传学证实乳腺病变的妇女进行了回顾性分析.
对SWI参数 (ILSS,边缘形态) 和ADC值的分析.
使用ROC分析评估的诊断性能和用科恩的 κ系数计算的观察者间协议.

主要成果:

恶性病变表现出更高的ILSS值比良性病变 (2.75对1.18).
恶性与SWI上的不规则边缘和不完整的边缘相关 (p < 0.001).
ILSS (0.86) 的曲线下的面积 (AUC) 比ADC (0.78) 高;综合AUC达到0.90.

结论:

SWI的诊断准确度相当于ADC的诊断准确度,用于乳腺病变的特征.
结合SWI和ADC值可以提高诊断的可靠性.
SWI,特别是边缘形态分析,为非对比的乳房MRI提供了有价值的补充信息.

关键词:

Magnetic Resonance Imaging

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...
