Development of navigation method for breast cancer operation using distortion correction and image fusion

临床应用60例。为了提高技术的准确性，还在手术室进行了与超声的图像融合，为了省略潜在的毒性造影剂，检查了扩散加权图像在乳腺癌中的应用。弥散加权图像的高诊断性能、高诊断性能和低b值的省略，以及对新辅助化疗后预后的良好预测。

Navigation techniques for breast cancer operation using contrast-enhanced CT was developed. Sixty cases underwent clinical application. Positive margin rate was lower than that using MRI navigation. Image fusion with ultrasound in the operation room was also performed in order to improve accuracy of the technique.For omission of potentially toxic contrast media, the usefulness of diffusion-weighted image in breast cancer was examined. High diagnostic performance, increased diagnostic performance with the omission of low b value, and a good predictor of prognosis after neo-adjuvant chemotherapy of diffusion-weighted images were demonstrated.
