Ovarian cancer is a genetically heterogeneous disease with a poor prognosis, and treatment individualisation could be aided by an ability to predict treatment outcome e.g. through measurements reflecting tumour blood supply. This study reports measurements of dynamic contrast enhanced MRI before and after neo-adjuvant chemotherapy, in primary ovarian tumour, omental cake and peritoneal deposits. A reduction in kep following treatment was found for ovarian and peritoneal tumours, with no change in the omental cake. There were no significant changes in Ktrans or area under the curve, possibly due to the small number of patients (14) studied so far.
