Magnetic resonance imaging (MRI) that measures the movement of water molecules in tumours may be the best way to monitor the response to treatment of women with advanced ovarian cancer, shows a study that compares different types of imaging in this group of patients.

The study compared three different MRI techniques and found that diffusion weighted MRI was the most effective for detecting the effects of treatment on primary ovarian tumours and on tumours that had metastasised to surrounding tissues (Radiology doi:10.1148/radiol.11110175).

Computed tomography has traditionally been used to assess whether patients with ovarian cancer should continue with chemotherapy after their first …
