Diagnostic value of breast digital X-ray combined with MRI in patients with Bi-RADS 4 suspicious malignant microcalcification
Objective To investigate the diagnostic value of digital X-ray combined with magnetic resonance imaging(MRI)in the evaluation of Bi-RADS 4 suspicious malignant microcalcification.Methods Seventy-nine patients with Bi-RADS 4 suspicious malignant microcalcifications of the breast who underwent surgical treatment at the Second People's Hospital of Kunshan City,Jiangsu Province,from June 2021 to July 2023 were selected for the study.All the patients underwent digital X-ray and MRI examination of the breast,and the diagnostic efficacy of the different exami-nation methods was analyzed by taking the pathological results as the"gold standard",and the characteristics of digital X-ray images and MRI fea-tures of the breasts of benign and malignant patients was analyzed.Results According to the"gold standard",there were 34 malignant patients and 45 benign patients,including 21 cases of fibroadenoma,12 cases of cystic hyperplasia,and 12 cases of mastitis.There were significant differences in the distribution of microcalcification in malignant patients,the proportion of amorphous shape,and the proportion of rough uneven shape benign and malignant patients(P＜0.05).There were significant differences in the proportion of each type of outflow time-signal intensity curve in malig-nant patients benign patients(P＜0.05).The specificity and accuracy,value of digital X-ray combined with MRI were higher than those of single detection(P＜0.05).Digital X-ray,MRI and digital X-ray combined with MRI were generally consistent with the"gold standard",with Kappa val-ues of 0.625,0.630,and 0.726,respectively.Conclusion Breast digital X-ray combined with MRI is of high value in the diagnosis of Bi-RADS 4 suspicious malignant microcalcification,which is helpful for clinicians to accurately judge the malignant possibility of patients with suspected mi-crocalcification.
