中文摘要：目的分析多模态高场磁共振成像(MRI)乳腺扫描诊断乳腺良恶性病变的临床价值.方法收集 2022 年 1月至 2023 年 12 月于河南科技大学第二附属医院进行乳腺MRI检查的 79 例乳腺患者的临床资料,所有患者入院后均接受高场MRI轴位T1加权成像(T1WI)、压脂T2加权成像(fs-T2WI)、扩散加权成像(DWI)、表观弥散系数(ADC)、动态对比增强(DCE),并将扫描的图像传至配套的后处理软件工作站建立病灶感兴趣区的动态增强曲线(DCE-TIC)及最大强度投影(MIP)图像、分析多模态高场MRI乳腺扫描在诊断乳腺良恶性病变方面的临床价值.结果以组织病理学检查结果作为金标准,79 例患者中发现 81 个病灶,其中良性病变 44 个,恶性病变 37 个,有 2 例患者存在 2 个病变并存的情况,1 例是左乳纤维腺瘤,右乳微小粘液癌,1 例是左乳发现 2 个病变,血管平滑肌瘤和叶状肿瘤并存.磁共振平扫、动态对比增强扫描和多模态高场MRI乳腺扫描诊断恶性病变的灵敏度分别为 72.97%、86.49%、94.59%,特异度分别为 54.55%、59.09%、81.82%,准确度分别为 62.96%、71.60%、87.65%,约登指数分别为 0.28、0.46、0.76.其中多模态高场MRI乳腺扫描诊断乳腺恶性病变效能最高,灵敏度、特异度、准确度及约等指数分别为 94.59%、81.82%、87.65%,0.76,高于单一做乳腺磁共振平扫或单做动态对比增强成像.结论多单一做乳腺平扫或DCE检查都有一定的不足,多模态高场MRI乳腺扫描诊断乳腺良恶性病变的诊断效能较好,对乳腺恶性病变诊断的准确性较高,对乳腺良恶性病变的诊断具有较高的临床价值.

外文标题：Diagnostic Value of Multimodal High-Field MRI Breast Scanning for Benign and Malignant Breast Lesions

外文摘要：Objective To analyze the clinical value of multimodal high-field magnetic resonance imaging(MRI)breast scanning in diagnosing benign and malignant breast lesions.Methods Clinical data of 79 breast patients who underwent breast MRI examination at The Second Affiliated Hospital of Henan University of Science and Technology from January 2022 to December 2023 were collected.All patients received high-field MRI axial T1-weighted imaging(T1WI),fat-suppressed T2-weighted imaging(fs-T2WI),diffusion-weighted imaging(DWI),apparent diffusion coefficient(ADC),and dynamic contrast-enhanced(DCE)imaging after admission.The scanned images were transmitted to the post-processing software workstation to dynamic contrast enchancement-time intensity curve(DCE-TIC)and maximum intensity projection(MIP)images of the lesion areas of interest.The clinical value of multimodal high-field MRI breast scanning in diagnosing benign and malignant breast lesions was analyzed.Results Using histopathological examination results as the gold standard,81 lesions were found in 79 patients,including 44 benign lesions and 37 malignant lesions.Two patients had coexisting lesions:one had a left breast fibroadenoma and a right breast micro-mucinous carcinoma,and one had two lesions in the left breast,including an angioleiomyoma and a phyllodes tumor.The sensitivity,specificity,accuracy,and Youden index of MRI plain scan,dynamic contrast-enhanced scan,and multimodal high-field MRI breast scanning in diagnosing malignant lesions were 72.97%,86.49%,94.59%;54.55%,59.09%,81.82%;62.96%,71.60%,87.65%;and 0.28,0.46,0.76,respectively.Among them,multimodal high-field MRI breast scanning had the highest diagnostic efficiency for malignant breast lesions,with sensitivity,specificity,accuracy,and Youden index of 94.59%,81.82%,87.65%,and 0.76,respectively,which were higher than those of single breast MRI plain scan or dynamic contrast-enhanced imaging.Conclusion Both single breast plain scan and DCE examination have certain limitations.Multimodal high-field MRI breast scanning has better diagnostic efficiency for benign and malignant breast lesions,with higher accuracy in diagnosing malignant breast lesions,and has high clinical value in differentiating benign and malignant breast lesions.
