The goal of this observational study is to learn about the added diagnostic and prognostic value of advanced medical imaging procedures in cervical cancer, endometrial cancer and ovarian cancer. The main questions it aims to answer are: * Does advanced medical imaging predict survival? * Can advanced medical imaging improve radiotherapy target planning? * Are advanced medical imaging results associated with risk markers found in tumor tissue? Participants will * Undergo four additional imaging procedures, as compared to clinical routine examinations, two at baseline and two after three months. * Be subject to clinical follow-up for five years.
