| Research Abstract |
In recent years, it has become clear that the hyperplasia of ablood vessel and the hyperplasia of a lymph vessel have correlation in a cancer. Cancer cells are metastasized through a lymph vessel. Then, since dynamic CE-MRI can perform the diagnostic imaging reflecting the blood flow in a tumor, the hyperplasia of the lymph vessel in a cancer was evaluated by dynamic CE-MRI. Correlation positive in dynamic CE-MRI and the number of the blood vessels in a tumor on a pathology specimen was shown. Moreover, although positive correlation was shown also between the number of the blood vessels in a tumor on a pathology specimen and the number of lymph vessels, correlation was not shown between dynamic CE-MRI and the number of lymph vessels on a pathology specimen. However, the significant difference was shown between dynamic CE- MRI of the primary lesion with lymph-nodes metastasis group and with non- lymph-nodes metastasis group.
