Abstract:

Objective   To explore the significance of 256 slice CT perfusion imaging and three-dimensional reconstruction technology for diagnosis and preoperative evaluation of breast disease.   Methods  50 patients found breast tumors by color doppler ultrasound or mammography underwent 256 slice CT perfusion scan, combined with the postoperative pathological results, analyzed the perfusion imaging indexes of different nature of breast neoplasm tissue and normal breast tissue, and three-dimensional reconstruction of guidance for clinical surgery.   Results   The perfusion imaging indexes of 256 slice CT had important reference value in differential diagnosis of benign and malignant breast tumors, three-dimensional reconstruction model could observe lesions in all situations, and provided the basis for preoperative assessment.   Conclusion   256 slice CT perfusion imaging can be helpful to differentiate the breast cancer from benign breast tumor from the aspects of hemodynamics. three-dimensional reconstruction can provide more information for clinical diagnosis, treatment, and help to preoperative evaluation of breast cancer.
