| Outline of Final Research Achievements |
Although the correlation with the prognostic factor of breast cancer is known as the improvement of the specificity in the discrimination between benign and malignant as the usefulness of diffusion weighted images in breast cancer, it is stated that the sequence is expected at the research level in the future Only. In the background, DWI believes that standardization is difficult, distortion in the breast region by EPI method, noise, magnetic susceptibility artifacts. In this research, DWI imaging of the TSE method was taken as a new method against the conventional EPI method, and the image quality and the diagnostic ability were compared. As a result, the TSE method is superior to the EPI method in terms of improving SNR and distortion, and imaging of DWI using the TSE method is considered to be an imaging method leading to standardization.
