钼靶联合MRI诊断乳腺导管原位癌的价值

Value of Mammography Combined with MRI in the Diagnosis of Ductal Carcinoma in Situ

目的:探讨钼靶联合MRI诊断乳腺导管原位癌(DCIS)的价值。方法:选取2015年10月至2023年10月本院50例经手术病理检查证实为DCIS患者为对象。入组患者均接受钼靶及MRI检查,分析MRI、钼靶诊断DCIS的准确度。结果:钼靶、MRI及联合检测诊断DCIS的准确度分别为52.00%、70.00%、88.00%。联合检测诊断DCIS的准确度高于钼靶、MRI(P<0.05)。钼靶检查可见31例(62.00%)患者伴有钙化,其中14例(45.16%)患者为段样分布钙化,13例(41.94%)患者为簇状钙化,4例(12.90%)患者为区域分布钙化。MRI扫描可见37例患者(74.00%)为非肿块样强化,其中12例(32.43%)为段样分布强化,11例(29.73%)为线样分布强化,10例(27.03%)为局灶性强化,4例(10.81%)为区域分布性强化。结论:钼靶与MRI联合检查可发挥各种的优势,提高DCIS诊断的准确率。

Objective:To evaluate the value of mammography combined with MRI in the diagnosis of ductal carcinoma in situ(DCIS).Methods:From October 2015 to October 2023,50 patients with DCIS confirmed by surgical pathological examination in our hospital were selected as the objects All enrolled patients received mammography and MRI,and the accuracy of MRI and mammography in diagnosing DCIS was analyzed.Results:The accuracy of molybdenum target,MRI and combined detection of DCIS were 52.00%,70.00%and 88.00%,respectively.The accuracy of combined detection in diagnosing DCIS was higher than that of molybdenum target and MRI(P<0.05).Molybdenum examination showed 31 patients(62.00%)with calcification,of which 14 patients(45.16%)had segmental distributed calcification,13 patients(41.94%)had cluster calcification,and 4 patients(12.90%)had regional distributed calcification.MRI scan showed that 37 patients(74.00%)had non-lump-like enhancement,of which 12 patients(32.43%)had segmental distribution enhancement,11 patients(29.73%)had linear distribution enhancement,10 patients(27.03%)had focal enhancement,and 4 patients(10.81%)had regional distribution enhancement.Conclusion:Molybdenum combined with MRI can play a variety of advantages and improve the accuracy of DCIS diagnosis.
