In those women with confirmed cancer on histology an MRI is performed to assess stage of cancer (current routine standard of care). This will include T1, T2, DWI and contrast enhanced sequences. Patients referred to Hammersmith Hospital from other trusts will also be able to undergo a 3D ultrasound if this was not already performed. Definitive management of endometrial cancer includes a hysterectomy and the surgical specimen will be examined for depth of myometrial invasion. In the meantime, the saved 3D ultrasound images will be analysed and rendered to predict the stage of the endometrial cancer. The results of 3D ultrasound, and MRI will be compared against the stage found on the gold standard test (on histological examination).
