Abstract

Objective: This study aimed to assess the diagnostic role of perfusion weighted image (DCE-PWI) to differentiate benign from malignant breast lesions.

Patients and methods: The study comprised 32 women who had mammography and/or breast ultrasonography findings that were clinically questionable. All patients were fasting during the magnetic resonance imaging (MRI) test to avoid nausea or dynamic contrast-enhanced vomiting from the contrast medium.

Result: In this study, we observed the form of the dynamic curve (time and signal intensity curve) type I (persistent curve) was noted in 12 lesions (37.5%): 10 lesions were benign and two lesions were malignant; type II (plateau curve) was noted in eight lesions (25%): three lesions were benign and five lesions were malignant, and type III (washout curve) noted in 12 lesions (37.5%): one lesion was benign and 11 lesions were malignant.

Conclusions: The dynamic contrast-enhanced (DCE) magnetic resonance imaging (MRI) perfusion technique plays an important role in differentiating benign and malignant tumors in breast cancer.

动态增强磁共振成像在乳腺病变鉴别中的诊断作用。
目的:探讨灌注加权图像(DCE-PWI)对乳腺良恶性病变的鉴别诊断价值。患者和方法:该研究包括32名有临床可疑的乳房x光检查和/或乳房超声检查结果的妇女。所有患者在磁共振成像(MRI)检查期间均禁食,以避免造影剂引起的恶心或动态对比增强呕吐。结果:在本研究中,我们观察到12个病变(37.5%)出现I型(持续曲线)的动态曲线形式(时间和信号强度曲线):10个病变为良性,2个病变为恶性;II型(平台曲线)病变8例(25%),良性3例,恶性5例;III型(洗脱曲线)病变12例(37.5%),良性1例,恶性11例。结论:动态对比增强(DCE)磁共振成像(MRI)灌注技术在鉴别乳腺癌良恶性肿瘤中具有重要作用。
