【摘要】：目的:探讨乳腺MRI检查对乳腺X线摄影中结构扭曲表现的诊断价值。方法:搜集2014年1月1日-2015年3月10日本院行乳腺X线摄影检查患者的相关临床、影像及病理资料,连续性纳入乳腺X线摄影诊断为腺体结构扭曲且术前行乳腺MRI检查的患者,排除病变部位有既往外伤或手术史的患者。最终入组32例病例,其中22例单纯结构扭曲,10例合并微钙化、局灶不对称致密或肿块等征象。分别分析X线摄影腺体结构扭曲伴有其他征象者、单纯性结构扭曲者的阳性预测值(PPV)及进一步MRI检查对诊断效能的影响。结果:乳腺X线摄影表现为腺体结构扭曲且有伴随征象者,PPV为66.7%(8/12),进一步MRI检查减少30%的假阳性诊断;表现为单纯结构扭曲者,PPV为9.1%(2/22),进一步MRI检查减少86.4%的假阳性诊断;未发现MRI漏诊病例。结论:对于乳腺X线摄影表现为单纯腺体结构扭曲者,进一步MRI检查能够显著提高PPV。
[Abstract]:Objective: to evaluate the diagnostic value of mammary MRI in structural distortion in mammography.Methods: the clinical, imaging and pathological data of patients undergoing mammography from January 1, 2014 to March 10, 2015 in our hospital were collected. The patients diagnosed by continuous mammography as distorted glandular structure and MRI before mammography were included in this study.Patients with previous trauma or surgical history were excluded from the lesion.Finally, 32 cases were included in the study, including 22 cases with simple structural distortion and 10 cases with microcalcification, focal asymmetry or mass.The positive predictive value (PPVs) and the effect of further MRI examination on the diagnostic efficacy were analyzed in patients with structural distortion of glandular structure and other signs in X-ray radiographs, and in patients with simple structural distortion (PPVs) and in patients with simple structural distortions (PPVs).No missed diagnosis of MRI was found.Conclusion: if mammography shows simple glandular structure distortion, further MRI examination can significantly improve PPVs.
