X数字化钼靶、超声及磁共振成像用于乳腺导管原位癌中的诊断价值

Diagnostic value of X-ray digital molybdenum target, ultrasound, and magnetic resonance imaging in ductal carcinoma in situ

目的探讨X数字化钼靶(MG)、超声及磁共振成像(MRI)三种检测方式对乳腺导管原位癌(DCIS)患者的诊断价值。方法选取2016年3月至2018年12月在本院接受治疗的67例DCIS患者资料进行回顾性分析,分别采用MG、超声及MRI检查,分析比较三种检测方式对DCIS的图像特征及诊断符合率。结果MG显示肿物伴钙化型12例,单纯肿物型1例,单纯钙化型42例;超声显示肿物伴钙化型9例,单纯肿物型41例,单纯钙化型0例;MRI显示非肿块样强化47例,单纯肿物型3例,肿物伴导管扩张8例;MG显示钙化占比显著高于超声(P<0.05);MRI对DCIS的诊断符合率明显高于超声(P<0.05);MG+超声+MRI联合诊断符合率明显高于单纯MRI、MG及超声检查(P<0.05)。结论MRI对DCIS的诊断符合率明显高于超声,但三者联合应用于DCIS的诊断价值更高。

Objective To explore the diagnostic value of X-ray digital molybdenum target (MG), ultrasound, and magnetic resonance imaging (MRI) in patients with breast ductal carcinoma in situ (DCIS). Methods A retrospective analysis was made on 67 DCIS patients treated in our hospital from March 2016 to December 2018. The image characteristics and diagnostic coincidence rate of DCIS were analyzed and compared by using MG, ultrasound, and MRI. Results MG showed 12 cases of tumor with calcification type, 1 case of simple tumor type, and 42 cases of simple calcification type. Ultrasound showed 9 cases of tumor with calcification type, 41 cases of simple tumor type, and 0 case of simple calcification type. MRI showed non-mass enhancement in 47 cases, simple mass type in 3 cases, tumor with duct dilatation in 8 cases. The proportion of calcification showed by MG was significantly higher than that by ultrasound (P<0.05). The diagnostic coincidence rate of DCIS by MRI was significantly higher than that by ultrasound (P<0.05). The coincidence rate of combined diagnosis of MG + ultrasound + MRI was significantly higher than those of simple MRI, MG, and ultrasound (P<0.05). Conclusion The diagnostic coincidence rate of DCIS by MRI is significantly higher than that by ultrasound. However, the combination of the three methods is more valuable in the diagnosis of DCIS.
