摘要

目的:本研究旨在利用乳腺成像报告与数据系统(BI-RADS)词汇描述符,定性评估乳腺2型动态曲线病变的弥散加权成像(DWI)和t2加权成像(T2WI)的附加诊断价值。材料和方法:我们回顾性分析了181例连续接受3-特斯拉(3-T)磁共振成像(MRI)的乳房2型动态曲线病变。训练有素的放射科医生使用BI-RADS词汇描述符评估病变在动态对比增强(DCE) MRI、DWI和T2WI上的形态学特征,并测量表观扩散系数(ADC)。对病变类型组(肿块样组与非肿块样组)的变量进行统计分析比较。采用受试者工作特征曲线下面积(AUC)和DeLong检验评价诊断效能,p <; 0.05有统计学意义。结果:在肿块样病变中,DCE、DWI、T2WI各形态参数均能显著区分良恶性病变(p < 0.05)。ADC值也有显著性差异(p < 0.05)。联合方法(DCE + DWI + T2WI)的AUC最高(0.895),显著优于单个方法(均p <; 0.05)。在非肿块样病变中,没有参数显著预测恶性(均p >; 0.05)。结论:使用BI-RADS词汇描述符对DWI和T2WI的增加进行解释,可以增强对2型动态曲线乳腺病变的鉴别诊断。

Morphological Assessment of Breast Lesions With Type 2 Dynamic Curves Using DWI and T2WI Based on Breast Imaging Reporting and Data System Lexicon Descriptors

Morphological Assessment of Breast Lesions With Type 2 Dynamic Curves Using DWI and T2WI Based on Breast Imaging Reporting and Data System Lexicon Descriptors

Purpose: This study aimed to qualitatively assess the added diagnostic value of diffusion-weighted imaging (DWI) and T2-weighted imaging (T2WI), using Breast Imaging Reporting and Data System (BI-RADS) lexicon descriptors, in evaluating breast lesions with type 2 dynamic curves.

Materials and Methods: We retrospectively reviewed 181 breast lesions with type 2 dynamic curves in 181 consecutive patients who underwent 3-Tesla (3-T) magnetic resonance imaging (MRI). Trained radiologists assessed the morphological features of the lesions on dynamic contrast-enhanced (DCE) MRI, DWI, and T2WI using BI-RADS lexicon descriptors and measured the apparent diffusion coefficient (ADC). Statistical analysis was performed to compare variables in lesion type groups (mass-like group vs. nonmass-like group). Diagnostic performance was evaluated using the area under the receiver operating characteristic curve (AUC) and the DeLong test, with statistical significance at p < 0.05.

Results: In mass-like lesions, all morphological parameters significantly distinguished benign from malignant lesions on DCE, DWI, and T2WI (all p < 0.05). ADC values also showed significant differences (p < 0.05). The combined approach (DCE + DWI + T2WI) yielded the highest AUC (0.895), significantly outperforming the individual methods (all p < 0.05). In nonmass-like lesions, no parameter significantly predicted malignancy (all p > 0.05).

Conclusion: The addition of DWI and T2WI, interpreted using the BI-RADS lexicon descriptors, enhances the differential diagnosis of breast lesions with type 2 dynamic curves.

期刊介绍: The Breast Journal is the first comprehensive, multidisciplinary source devoted exclusively to all facets of research, diagnosis, and treatment of breast disease. The Breast Journal encompasses the latest news and technologies from the many medical specialties concerned with breast disease care in order to address the disease within the context of an integrated breast health care. This editorial philosophy recognizes the special social, sexual, and psychological considerations that distinguish cancer, and breast cancer in particular, from other serious diseases. Topics specifically within the scope of The Breast Journal include: Risk Factors Prevention Early Detection Diagnosis and Therapy Psychological Issues Quality of Life Biology of Breast Cancer.
