概括

在高T2信号病变上的乳房MRI导向真空辅助活检 (MVAB) 显示了20%的恶性瘤率. 仅仅T2高强度不足以排除癌症;考虑患者的年龄和MRI特征.

科学领域:

放射学放射学是一门学科.
在瘤学瘤学.
病理学病理学病理学

背景情况:

乳房MRI上的高T2信号可能含糊不清.
真空辅助活检 (MVAB) 用于可疑的病变.

研究的目的:

评估MVAB对高T2信号乳腺病变的结果.
确定这些病变中恶性瘤的预测因素.

主要方法:

对于高T2病变的174个MVAB程序的回顾性审查.
对与病理结果相关的人口和成像特征的分析.

主要成果:

20%的恶性瘤发生率 (DCIS,IDC),38%的良性瘤发生率 (FCC).
年龄较大,洗动力学和疾病程度表明预测恶性瘤.
损伤大小和形态不是显著的预测因素.

结论:

单独的T2高强度对于排除恶性瘤是不可靠的.
纳入患者的年龄,运动特征和MRI指示,以提高诊断准确度.

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...
