Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
All study patients will have a diffusion weighted MRI scan prior to surgery.
This is a single MRI which will take approximately 1 hour to perform. It will be performed up to a week prior to surgery.

Three T high field strength MR scanner will be used . High performance gradients (50 mT/m, 200 mT/m/sec) are advantageous for high quality DW imaging.

The MRI scan will be performed by the MRI radiographer with the radiologist supervising.

Intravenous gadolinium contrast will be administered using a power injector at an injection rate of 2 cc per second. We will use a single dose 0.1 mmol/kg of MultiHance® (gadobenate dimeglumine) (Bracco).

Key exclusion criteria
• Patients who have a heart pacemaker may not have an MRI scan
• Patients who have a metallic foreign body (metal sliver) in their eye, or who have an aneurysm clip in their brain, cannot have an MRI scan since the magnetic field may dislodge the metal
• Patients with severe claustrophobia may not be able to tolerate an MRI scan, although more open scanners are now available, and medical sedation is available to make the test easier to tolerate
• Patients who have had metallic devices placed in their back (such as pedicle screws or anterior interbody cages) can have an MRI scan, but the resolution of the scan is often severely hampered by the metal device and the spine is not well imaged.

Efficacy
Statistical methods / analysis
We used the sample size recommended by Bland(2004) based on the Bland Altman method (Bland +Altman 1986) This guideline is not based on a formal powering process as the Bland-Altman approach is not inferential. Bland 2004 recommends a sample of at least 100 patients for the Bland –Altman approach.

We employed both the ICC (Intra class correlation) and the Bland Altman approach to guage both inter-method and inter-rater (within MRI) agreement. The ICC was used as it provides a single measure of agreement with a 95% CI. Where as Bland Altman was used because it is much more informative about the specific causes of lack of agreement (bias, Noise, Spectrum Bias, Spectrum noise) Bland Altman is also much more intuitive.

We will compare the radiologically scored PCI with the surgically scored PCI using paired t-testing

Summary
Brief summary
This research study is designed to assess whether a special MRI scan can accurately predict the extent of cancer spread in the abdominal cavity in advanced ovarian cancer.

Who is it for?
You may be eligible for this study if you have a diagnosis of metastatic ovarian cancer and are aged over 18 years old.

Study details
All participants in this study will undergo an MRI scan no longer than 2 weeks prior to their routine diagnostic laparoscopy. This scan will take approximately 60 minutes. Participants will also give informed consent for access to their medical records.

It is hoped this research might demonstrate that MRI scans can replace surgery when assessing the spread of advanced ovarian cancer in the abdominal cavity.

Public notes
The aim of the study is to compare the radiologically scored PCI with our surgically scored PCI. We will determine if MRI can replace laparoscopy in the work up for ovarian cancer definitive surgery. The primary objective is to assess if MRI scored PCI equates to surgically scored PCI. The secondary objectives are to identify if personal factors affect the sensitivity of the test (ethnicity, body habitus, age, diabetes, smoking status, neoadjuvant chemotherapy, histology), and to assess the need for an experienced abdominal radiologist versus a junior radiologist in performing accurate scoring.
Patients will be diagnosed with ovarian cancer in the standard manner. This includes assessment of symptoms, tumour markers, a CT scan, an ultrasound scan, histological or cytological testing and an exploratory laparoscopy. After this assessment, patients are deemed suitable for primary surgery or primary chemotherapy based on our ability to remove all of their disease. The management of patients will not change in this study. The only addition to management will be the addition of a diffusion weighted MRI scan prior to the exploratory laparoscopy. Patients will be consented for participation in the study at the outpatient clinic by a senior member of the team. The MRI scan will be done at the radiology department at the Mater Hospital.

The MRI scan will take up to 60 minutes. Patients will have intravenous and oral contrast for best visualisation of the colon. Standard comfort measures will be taken as for all MRI imaging. Each patient will continue with standard laparoscopic assessment of their disease and PCI scores from two radiologists will be compared to those taken by the surgeon intra-operatively.
