| Outline of Final Research Achievements |
It is often difficult to diagnose the anterior mediastinal tumors because of their similar imaging findings. We evaluated the utility of the monoenrrgetic imaging method for improving differential diagnosis of the mediastinal tumors by using dual energy CT. We compared the gradient of CT numbers of 40-100 keV and 40-110 keV at non-contrast CT, early and delayed phase contrast enhanced CT for the three mediasitnal tumors; thymic epithelial tumors (TET), lymphoma, and cystic tumors, respectively. There were significant differences between cystic tumors and TET, lymphoma, respectively (p <0.05).
