Ou Jian, director of Gynecological Oncology Surgery, Resigned from the clinical work of gynecological radiotherapy in Jilin Cancer Hospital and joined the Guowen Medical corporation Changchun hospital. She specializes in precision radiotherapy for gynecological tumors, three-dimensional afterloading and three-dimensional brachytherapy, chemotherapy for gynecological malignant tumors, molecular targeted therapy and individualized comprehensive therapy. She is especially good at MRI-guided brachytherapy for gynecological malignant tumors. Compared with the traditional CT-guided brachytherapy, it has the advantages of higher tumor treatment accuracy and lower side effects, which is at the advanced level at home and abroad.
MRI-guided 3D brachytherapy
Project Description.
MRI-guided three-dimensional brachytherapy is brachytherapy guided by MRI image positioning, while most domestic radiotherapy centers still use CT positioning for three-dimensional brachytherapy.
The advantage of MRI over CT is the superior soft tissue resolution, which is especially crucial for the outline of brachytherapy target area for cervical cancer, a common gynecological malignancy. Compared with CT, MRI can better display the extent of parametrial and tumor invasion during brachytherapy target area outline, avoiding over-evaluation of tumor extent under CT guidance, which further shrinks the isodose curve, thus providing higher MRI can better show the extent of parametrial and tumor invasion when outlining the target area, avoiding the over-evaluation of tumor extent under CT guidance and further shrinking the isodose curve, thus providing higher dose to the target area and better protection of surrounding organs. It can improve the tumor control rate and reduce the side damage to normal organs of patients.
