概括
快速T2加权MRI与脂肪抑制 (T2-FS) 比扩散加权成像 (DWI) 更敏感,用于检测多发性骨髓瘤骨病变. 添加DWI并没有改变患者管理,而FDG PET在少数情况下改变了管理.
科学领域:
- 放射学和成像科学 放射学和成像科学
- 瘤成像学成像学
背景情况:
- 18F-氧葡萄糖正子发射断层扫描 (FDG PET) 和全身 (WB) MRI 与扩散权重成像 (DWI) 是多发性骨髓瘤评估的既定方法.
- 长时间的扫描时间和文物限制了WB DWI; 快速的T2加权MRI与2点迪克森脂肪抑制 (T2-FS) 提供了更快的骨损伤检测替代方案.
研究的目的:
- 评估快速WB T2-FS的诊断准确性,以检测多发性骨髓瘤病变.
- 评估添加DWI和FDG PET到T2-FS对诊断准确性和患者管理的增量影响.
主要方法:
- 在多发性骨髓瘤患者的31个WBPET/MRI检查的回顾性分析.
- 由两位读者对T2-FS,DWI和PET进行独立的盲目审查,以确定焦点病变和非焦点骨髓疾病.
- 使用McNemar的精确测试对每病变和每患者的敏感性和特异性的比较.
主要成果:
- 与DWI (66.7%) 和FDG PET (44.4%) (P<0.001) 相比,T2-FS表现出明显更高的每损伤敏感性 (91.9%).
- T2-FS确定了所有患有疾病的患者 (100%),而DWI和FDG PET的患者为85.7% (P>0.050).
- 将DWI添加到T2-FS并没有改变患者管理;添加FDG PET改变了31名患者中的3名患者的管理.
结论:
- 与WB DWI相比,快速WB T2-FS是多发性骨髓瘤评估的更敏感和更快的成像技术.
- 虽然FDG PET可以影响管理,但将DWI添加到T2-FS似乎不会影响临床决策.
- 建议通过更大的前性研究进一步验证多发性骨髓瘤成像中的T2-FS.

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...

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,...
