Abstract
Objective To study the application value of diffusion weighted imaging (DWI) combined with time-signal intensity curve (TIC) in the diagnosis of breast cancer.Methods 28 cases of breast cancer and 25 cases of breast benign lesions were performed DWI and DCE-MRI examination.The morphological features,TIC curve shape and distribution,ADC values of patients with breast benign lesions and breast cancer were compared.The sensitivity,specificity,and accuracy of combined diagnosis and single diagnosis were compared.Results The form of MRI dynamic enhancement in breast benign lesions was given priority to class round (76.0％),edge was given priority to smooth (72.0％),the form of breast cancer was given priority to leaf shape (60.7％),edge was given priority to burr indications (60.7％),with statistically significant differences between the two groups (P＜0.05).The TIC curve of breast benign lesions was given priority to Ⅰ type (68.0％),malignant lesions was given priority to Ⅲ type (78.6％),with statistically significant difference between the two groups (P＜0.05).ADC values of 78.6％ breast cancer were ≤ 1.22× 10-3 mm2/s,ADC values of 80.0％ breast benign lesions were ＞1.22× 10-3 mm2/s,with statistically significant difference between the two groups (P＜0.05).The sensitivity,specificity,and accuracy of both diagnosis of benign and malignant breast lesions were significantly higher than those of single dynamic enhanced magnetic resonance or diffusion weighted imaging diagnosis (P＜0.05).Conclusion DWI combined with TIC has a high clinical value in the diagnosis of breast cancer.关键词
