【摘要】：目的评估MRI引导下定位活检对仅MRI显示乳腺病变的应用价值。方法搜集52例56个MRI上显示而其他影像技术难以显示的隐匿病灶。全部病灶BI-RADS分类4级或4级以上。采用1.5 T超导MRI仪,乳腺MRI专用定位活检穿刺架及乳腺MRI专用定位针和定位导丝。根据MRI检查发现可疑病灶的部位选择外侧位、内侧位或轴位行定位活检。观察操作方式及定位准确性。结果 52例56个病灶均一次定位成功,病理切片证实病变完全切除,成功率达100%。病理结果:52例56个病灶中乳腺导管内癌8个,浸润型癌7个,乳腺导管内乳头状瘤病1个,乳腺导管上皮不典型增生7个,乳腺腺病伴高度增生20个,乳腺纤维腺瘤13个。术前MRI诊断与术后病理结果对照MRI诊断符合率89.29%(50/56)。结论对仅MRI显示的乳腺隐匿病灶,MRI导引的定位活检是一种安全可靠的方法,弥补了其他影像方法的不足及假阴性的发生,是对钼靶和超声引导乳腺定位活检的重要补充,为微创手术治疗提供了又一种精确导向的方式。
[Abstract]:Objective to evaluate the value of MRI guided biopsy in the diagnosis of breast lesions only by MRI. Methods 52 cases (56 cases) with occult lesions displayed on MRI but difficult to display by other imaging techniques were collected. All lesions were classified by BI-RADS in grade 4 or above. 1.5T superconducting MRI apparatus, breast MRI specific biopsy frame, breast MRI special positioning needle and guiding wire were used. According to MRI examination, the location of suspected lesions was located in lateral, medial or axial position. Observe the operation mode and positioning accuracy. Results all the 56 lesions in 52 cases were located successfully in one time. The pathological section proved that the lesions were resected completely, and the success rate was 100%. The pathological results showed that there were 8 breast ductal carcinoma, 7 invasive carcinoma, 1 intraductal papillomatosis, 7 atypical hyperplasia of ductal epithelium, 20 high hyperplasia of mammary gland adenosis and 13 fibroadenoma. The coincidence rate of preoperative MRI diagnosis and postoperative pathological results in MRI diagnosis was 89.29% or 50% 56%. Conclusion the MRI-guided localization biopsy of breast occult lesions displayed only by MRI is a safe and reliable method, which makes up for the deficiency of other imaging methods and the occurrence of false negative. It is an important supplement to mammography and ultrasound guided mammary gland localization biopsy. It provides another kind of precise guidance for minimally invasive surgical treatment.
