PDFAbstract
Objective To explore the imaging features of MRI diffusion weighted imaging (DWI) and dynamic enhanced Time-Signal intensity curve (TIC) in the differential diagnosis of benign and malignant breast lesions, so as to improve the diagnostic accuracy and avoid misdiagnosis. Methods The clinical and imaging data of 52 patients with pathologically confirmed breast lesions were retrospectively analyzed. Conventional MRI, DWI and TIC were compared to evaluate the superiority of DWI combined with TIC in differential diagnosis of benign and malignant breast lesions. Results The apparent diffusion coefficient of benign and malignant breast lesions was significantly different (P<0.05). The difference of TIC in benign and malignant lesions was statistically significant (P<0.05). The sensitivity, specificity and accuracy of joint diagnosis with ADC or TIC were significantly different (all P<0.05). Conclusion ADC value combined with TIC can assist in the diagnosis of benign and malignant breast lesions, which is more valuable than single index alone.
