概括

放射科医生的经验显著提高了高风险女性乳腺MRI查的诊断准确性. 增加MRI阅读经验可以提高恶性或高风险病变的检测,即使具有更高的背景辅酶增强.

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:

高风险妇女从每年的乳房MRI查中受益.
影响可疑MRI结果准确性的因素需要进行调查.

研究的目的:

评估放射学家经验,背景体增强 (BPE) 和纤维腺组织 (FGT) 对乳房MRI用于检测可疑发现的预测价值和准确性的影响.

主要方法:

分析 BI-RADS 4/5 乳腺MRI 结果与来自省级查计划的病理诊断 (n=536).
计算活检证明的预测值 (PPV3) 和用于诊断准确性的逻辑回归,考虑到放射科医生的经验,BPE和FGT.

主要成果:

放射科医生经验与检测恶性或高风险病变 (OR=1.05,p=0.03) 有显著的相关性.
随着经验的增加,诊断的准确性呈指数级提高 (5年:OR=1.27;10年:OR=1.61,p=0.03).
较低的BPE水平与恶性瘤的几率增加有关,独立于FGT和经验.

结论:

增加乳腺MRI阅读经验可以提高放射科医生的高风险和恶性病变的诊断准确性.
经验仍然是改善诊断绩效的关键因素,即使在具有较高背景辅酶增强的病例中也是如此.

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...
