目的 探究导管造影钼靶X线与磁 共振(MRI)检查在乳腺导管内乳头状瘤诊 断中的价值及其影像表现差异。方法 选 取52例经病理检查确诊的乳腺导管内乳头 状瘤患者为研究对象,均接受影像检查。 比较导管造影钼靶X线检查和MRI检查对乳 腺导管内乳头状瘤病理诊断的符合率差 异，分析其影像表现。结果 导管造影钼 靶X线检查与病理诊断符合43例(82.7%)， MRI检查符合44例(84.6%)，组间比较无统 计学意义(P>0.05)。52例患者中35例X线 钼靶平片无异常发现，但所有患者导管造 影钼靶X线检查均可见异常表现：可见明 显肿块影者31例、导管膨胀13例、导管扭 曲8例。MRI图像可见囊状扩张的导管内结 节样病灶者13例，乳腺内未见明显扩张导 管且病灶呈实性结节样形态者39例；病灶 明显均匀强化45例，不均匀强化6例，未 见明显强化1例。结论 两种检查方式均在 乳腺导管内乳头状瘤的诊疗中具有较高的 应用价值，建议联合使用，以此降低误诊 及漏诊风险。

Objective To explore the value of galactography molybdenum target X-ray and magnetic resonance imaging (MRI) in the diagnosis of breast intraductal papillomas and the differences of imaging findings. Methods A total of 52 patients with breast intraductal papillomas diagnosed by pathological examination were selected as the study subjects, and all of them underwent imaging examination. The coincidence rates of galactography molybdenum target X-ray and MRI examination with pathological diagnosis for breast intraductal papillomas were compared, and the imaging findings were analyzed. Results There were 43 cases (82.7%) detected by galactography molybdenum target X-ray, accordant with pathological diagnosis and there were 44 cases (84.6%) detected by MRI, accordant with pathological diagnosis (P>0.05). Among the 52 subjects, the plain films of molybdenum target X-ray of 35 cases showed no abnormal findings. However, the galactography molybdenum target X-ray of all subjects showed abnormal findings, including obvious mass shadow in 31 cases, tube expansion in 13 cases and ductal distortion in 8 cases. MRI showed that there were 13 cases with cystic dilating intraductal nodular lesions and 39 cases without obvious dilating catheter and with solid nodular lesions. The lesions showed obviously homogeneous enhancement in 45 cases, inhomogeneously enhancement in 6 cases and no obviously enhancement in 1 case. Conclusion Both of the two examinations are of high value in the diagnosis and treatment of breast intraductal papillomas. It is recommended that the two be combined to reduce the risk of misdiagnosis and missed diagnosis.
