Abstract
PURPOSE
To investigate the visibility of mammographically occult breast cancers on diffusion-weighted MRI (DWI) versus ultrasound.
MATERIALS AND METHODS
Mammographically occult breast cancers (n=60) initially detected on contrast-enhanced MRI that underwent pre-biopsy targeted ultrasound were retrospectively evaluated for visibility on DWI and ultrasound.
RESULTS
More cancers were visible on DWI than ultrasound (78% vs. 63%; p=0.049), with 32 (53%) visible on both and 7 (12%) not visible on either. Visibility differences were more significant in larger lesions (92% vs. 68%, p=0.006).
CONCLUSION
DWI may detect more mammographically occult cancers than ultrasound, warranting further investigation as an alternative supplemental screening technique.
摘要
目的
探讨在扩散加权磁共振成像（DWI）与超声检查中，乳腺钼靶隐匿性乳腺癌的可视性。
材料与方法
对60例最初在对比增强磁共振成像上发现、并在活检前接受靶向超声检查的乳腺钼靶隐匿性乳腺癌进行回顾性评估，以确定其在DWI和超声检查中的可视性。
结果
DWI上可见的癌症比超声检查更多（78%对63%；p=0.049），32例（53%）在两者上均可见，7例（12%）在两者上均不可见。在较大病变中，可视性差异更显著（92%对68%，p=0.006）。
结论
DWI可能比超声检测出更多的乳腺钼靶隐匿性癌症，作为一种替代性补充筛查技术值得进一步研究。
