Clinical Effectiveness of Magnetic Resonance Imaging Combined with Multimodal Ultra-sound in Differential Diagnosis of Benign and Malignant Breast Tumors
Objective To explore the differential diagnostic efficacy of magnetic resonance imaging(MRI)combined with multimodal ultrasound in breast tumors.Methods 92 female patients with breast occupying lesions were selected as the re-search subjects.MRI and multimodal ultrasound were performed on all patients,with pathological examination results as the"gold standard"to explore the application effect of MRI +multimodal ultrasound combined examination for benign and malignant breast tumors.Results Among the 92 cases of breast occupying lesions,31 cases(33.70%)were confirmed as malignant and 61 cases(66.30%)as benign by pathological examination;A total of 30 cases were diagnosed as malignant by MRI combined with multi-modal ultrasound,25 cases were diagnosed as malignant by MRI,and 23 cases were diagnosed as malignant by multimodal ultra-sound;The sensitivity[93.55%(29/31)],accuracy[96.74%(89/92)],and negative predictive value[96.77%(60/62)]of MRI combined with multimodal ultrasound in the differential diagnosis of breast tumors were higher than those of MRI and multi-modal ultrasound alone,with statistically significant differences(P<0.05);There was no statistically significant difference in the specificity and positive predictive value between MRI and multimodal ultrasound alone and in combination(P>0.05).The Kappa test showed excellent consistency between the results of MRI combined with multimodal ultrasound and the"gold standard"(Kap-pa value =0.926,P =0.000);The consistency between MRI and multimodal ultrasound alone and the"gold standard"was rela-tively ideal(kappa values =0.636,0.642,P =0.000,0.000).Conclusion The combination of MRI and multimodal ultrasound has a significant effect in the differential diagnosis of benign and malignant breast tumors,which can effectively improve the sensi-tivity and accuracy of malignant tumor diagnosis.It has high clinical application value and is worth vigorously promoting.
