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).

Outcomes
Primary outcome [1] 306573 0
assess the extent of cancer assessed by Peritoneal Cancer Index (PCI) using MRI
Timepoint [1] 306573 0
Surgically score PCI will occur in theatre and Radiologically scored PCI will occur up to a week before surgery.
Primary outcome [2] 307973 0
assess the extent of cancer seen at surgery assessed Peritoneal Cancer Index (PCI) determined by surgeon
Timepoint [2] 307973 0
Surgically score PCI will occur in theatre
Secondary outcome [1] 348917 0
Comorbidities as assessed by data-linkage to medical records. These include the presence or absence of cardiac disease, respiratory disease, a history of heart attack or stroke, the presence of diabetes,

Timepoint [1] 348917 0
This data will be recorded at the clinical consultation prior to both the MRI and the surgery. It is standard clinical data collection in this condition

Can healthy volunteers participate?
No
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
