摘要
目的旨在比较动态增强MRI以及乳腺钼靶在致密型乳腺病变的诊断效能。方法选取本院2017年3月至2019年1月收治的88例致密型乳腺病变的患者,所有患者均经MRI、钼靶检查。观察患者两种检查影像学表现,并与病理诊断结果为基准比较两种检查诊断正确率。结果88例患者中,乳腺钼靶检查确诊78.40%(69/88),MRI为92.04%(81/88)。明显优于乳腺钼靶检查(P<0.05)。乳腺钼靶检查良、恶性诊断正确率分别为80.00%、63.15%,动态增强MRI分别为92.00%、92.10%,(P<0.05)。良性病变肿块数边界清晰,以圆形为主,4例患者出现“大导管征”;恶性病变肿块为边界不清分叶状,6例患者有“毛刺征”,2例透亮环,可有恶性钙化及“大导管征”出现,1例淋巴癌栓。良性病变时间-信号曲线类型多为Ⅲ型,恶性病变为Ⅰ型或Ⅱ型。结论动态增强MRI诊断致密型乳腺病变正确率优于钼靶,钼靶在对细微病灶检测上有一定优势,钼靶可作为辅助补充检查手段。
Objective to compare the diagnostic efficacy of dynamic enhanced MRI and mammography for dense breast lesions.Methods 88 patients with dense breast lesions admitted to our hospital from March 2017 to January 2019 were selected.All patients underwent MRI and mammography.the imaging findings of the two examinations of the patient were observed and compared.the results of pathological diagnosis were used as a benchmark to compare the accuracy of the two examinations.results Among the 88 patients,the diagnosis rate of mammography was 78.40%(69/88),and the diagnosis rate of MRI was 92.04%(81/88),which was significantly better than that of mammography(P<0.05).the diagnostic accuracy of mammography for benign and malignant breast lesions was 80.00%and 63.15%,respectively,and the diagnostic accuracy of dynamic enhancement MRI was 92.00%and 92.10%,respectively(P<0.05).the boundary of benign lesions was clear and circular mainly.4 patients had big catheter sign.the boundary of the malignant lesion was unclear and lobulated,6 patients had burr signs,2 cases had translucent rings sign,but they had malignant calcification and big catheter sign.1 patient had a lymphatic tumor thrombus.the type of benign lesion time-signal curve was mostly typeⅢ,and type of malignant lesion time-signal curve was typeⅠor typeⅡ.Conclusion the correct rate of dynamic enhanced MRI in the diagnosis of dense breast lesions is superior to that of molybdenum targets.the molybdenum target has certain advantages in the detection of subtle lesions.the molybdenum target can be used as an auxiliary supplementary examination.
