摘要

Background Imaging the perfusion of contrast media in breast tumors may allow improved diagnosing and treating breast cancer. Purpose To compare the perfusion curve f (t) characteristics of contrast-enhanced ultrasonography in benign and malignant breast tumors. Material and Methods Patients with breast tumors (n = 87) were evaluated with contrast-enhanced ultrasonography and the perfusion curve f (t) parameters were calculated using Sonoliver(?) software to compare analysis (tumor) and reference (normal) tissue areas. Differences between breast and breast tumors were assessed. Results Compared to benign tumors, malignant tumors had faster enhancement time and a shorter mean transit time (all P values < 0.05). The intensity of the signal was also greater for malignant compared with benign tumors. Conclusion Perfusion curve f (t) parameter measurements can distinguish differences in vascular flow between malignant and benign breast tumors and may provide a new quantitative indicator of breast tumor.
