Clinical value of magnetic resonance dynamic enhancement in breast cancer diagnosis

To analyze the application effect of magnetic resonance dynamic enhancement in the diagnosis of breast cancer. 126 patients with suspected breast cancer who were examined in imaging were selected and their clinical data were retrospectively analyzed. The patients were divided into benign breast lesion group(67 cases) and breast cancer group(59 cases) according to their pathological results. All patients underwent magnetic resonance dynamic enhancement scanning and ultrasonography before surgery. The diagnostic effects of magnetic resonance dynamic enhancement scanning and ultrasonography were compared. The imaging characteristics of the two groups were observed, and the reflux rate constant, transport constant and volume fraction blood flow parameters were compared between the two groups. The diagnostic effect of magnetic resonance dynamic enhancement scanning was better than that of ultrasonography. The percentage of lesions with irregular shape, burr sign, increased vascularity, uneven enhancement, and blurred borders was higher in breast cancer patients than in benign breast lesions group(P<0.05). The reflux rate constant, transport constant and volume fraction of patients in breast cancer group were significantly higher than those in benign breast lesion group, and reflux rate constant, transport constant and volume fraction of patients with highly malignant breast cancer were higher than those of the patients with low-grade malignant breast cancer(P<0.05).Resonance enhancement scanning can improve detection rate of early breast cancer, and can also quantitatively analyze blood flow characteristics of lesion with the help of blood flow parameters, which can provide a reference for judging the condition and evaluating the prognosis.
