目的观察3.0T磁共振成像(MRI)与数字钼靶X线在诊断乳腺病变中的应用价值。方法选取2014年1月-2015年5月期间在该院就诊的64例乳腺病变患者的临床资料作为回顾性分析材料,所有患者均经3.0T MRI及数字钼靶X线诊断,以手术后病理组织检查结果作为判断标准,对3.0T MRI、数字钼靶X线的诊断结果进行分析判断。结果 64例患者病理组织检查显示良性病变34例、恶性病变30例。3.0T MRI平扫+弥散加权成像(DWI)检出率为76.56%,3.0T MRI增强扫描检出率为98.44%;3.0T MRI诊断符合率为98.44%,数字钼靶X线诊断符合率为71.88%,经纳入统计学检验诊断符合率,结果显示差异具有统计学意义(P<0.05);3.0T MRI诊断乳腺病变的敏感性、特异性、阳性预测值及阴性预测值均较数字钼靶X线更高,差异均有统计学意义(P<0.05)。结论 3.0T MRI检查乳腺病变的敏感性、特异性均更高,在临床诊断中具有一定价值。必要时可联合两种检测手段,以进一步提高检测准确性。
Objective To observe the value of 3.0T magnetic resonance imaging (MRI) and digital mammography X-ray in the diagnosis of breast lesions. Methods The clinical data of 64 cases of breast lesions in our hospital from January 2014 to May 2015 were retrospectively analyzed. All the patients were diagnosed by 3.0T MRI and digital mammography. The postoperative pathology Tissue test results as a criterion for the diagnosis of 3.0T MRI, digital mammography X-ray analysis to determine. Results 64 cases of pathological examination showed benign lesions in 34 cases, 30 cases of malignant lesions. 3.0T MRI scan + diffusion weighted imaging (DWI) detection rate was 76.56%, 3.0T MRI enhanced scan detection rate was 98.44%; 3.0T MRI diagnosis coincidence rate was 98.44%, the digital mammography X-ray diagnosis coincidence rate was 71.88% respectively. The coincidence rate was statistically significant (P <0.05). The sensitivity, specificity, positive predictive value and negative predictive value of 3.0T MRI in diagnosis of breast lesions were higher than those of mammography X-ray higher, the difference was statistically significant (P <0.05). Conclusion The sensitivity and specificity of 3.0T MRI in the diagnosis of breast lesions are higher, which is of great value in clinical diagnosis. When necessary, two detection methods can be combined to further improve the detection accuracy.
