Abstract:
Objective To explore the accuracy and influencing factors of contrast-enhanced spectral mammography(CESM)and MRI in the dimension measurement of breast lesions.Methods A retrospective analysis was performed on 104 patients with breast lesions who underwent CESM and MRI examinations within one week.The pathological size was used as the gold standard to com-pare the accuracy of the two measurement methods.Logistic regression analysis was used to compare the influencing factors of the measurement accuracy of CESM and MRI.Results The measured values of CESM,MRI and pathology were 1.70 cm(1.20-2.70 cm),1.65 cm(1.20-2.28 cm),1.75 cm(1.00-2.50 cm),respectively,and there were no statistically significant differences between the two measurement methods and the pathological results(P＞0.05).Bland-Altman plot analysis showed that 95.2％(99/104)of the differences in CESM fell within the consistency interval,and 93.3％(97/104)of the differences in MRI fell within the consistency interval.Logistic regression analysis showed that the independent risk factors affecting the accuracy of CESM and MRI measurement were lesion size and enhancement type.Conclusion Both CESM and MRI show good accuracy.As a potential alternative to MRI technology,CESM can be used for imaging evaluation of breast lesion size.
