Comparison of CT-based and MRI-based high-risk clinical target volumes in image guided-brachytherapy for cervical cancer, referencing recommendations from the Japanese Radiation Oncology Study Group (JROSG) and consensus statement guidelines from the Groupe Européen de Curiethérapie-European Society for Therapeutic Radiology and Oncology (GEC ESTRO)
The Working Group of the Gynecological Tumor Committee of the Japanese Radiation Oncology Study Group (JROSG) published recommendations for contouring high-risk clinical target volumes (HR-CTV) on CT for 3-dimentional image-guided brachytherapy for cervical cancer. The purpose of this study was to compare HR-CTV delineated on CT, referencing recommendations from JROSG, with HR-CTV delineated on MRI, referencing consensus guidelines from the Groupe Européen de Curiethérapie-European Society for Therapeutic Radiology and Oncology (GEC ESTRO). Fourteen patients were evaluated. After the insertion of the CT/MR applicator into the patient, CT and MRI were performed. HR-CTV The median volumes of HR-CTV Somewhat difference could be seen between HR-CTV
