Description of intervention(s) / exposure
The study involves an additional MRI scan being required for the study. This will require attendance at one MRI scan session of a half hour duration from the participant. This modification does not affect the gold standard of imaging the patients would otherwise receive for their treatment. This MRI scan will be undertaken at the Diagnostic Imaging Department, Calvary Mater Newcastle, scheduled on the same day as the participants planning CT scan. There will be no change to the participant’s treatment in this study – they will receive the gold standard of care and treatment as per departmental protocols. The MRI scan will be used for comparative purposes only.
The MRI will be used to create a "synthetic CT scan" which will be used prospectively to compare to the participants previously acquired CT scan

Outcomes
Primary outcome [1] 303442 0
This is a composite primary outcome to demonstrate the mean dosimetric agreement and 95% confidence interval between conventional CT and synthetic CT for radiotherapy treatment planning of cancers of the rectum, anal canal, endometrium and cervix
Timepoint [1] 303442 0
after completion of radiotherapy treatment planning
Secondary outcome [1] 338941 0
To demonstrate the Hounsfield Unit comparison of conventional CT and synthetic CT for complex pelvic cancers using mean absolute error
Timepoint [1] 338941 0
after completion of radiotherapy treatment planning
Secondary outcome [2] 338942 0
To demonstrate the generation of digitally reconstructed radiographs (DRR’s) from synthetic CT for on treatment guidance. A mock image guidance alignment will be performed using synthetic CT DRR based alignment and cone-bean CT based alignment. The differences in these measurements compared to the gold standard CT will be quantified

Statistical methods / analysis
The sample size will consist of 40 patients (20 male and 20 female patients) diagnosed with histologically confirmed malignancy of the rectum, anal canal, cervix or endometrium indicated for definitive radiotherapy, and who are eligible to undergo an MRI examination.
Prior experience in early phase development of the synthetic CT software suggests that a minimum sample of 20 participants is required to create an accurate sCT atlas. The contouring atlas which is used for this study to develop the synthetic CT scans cannot generalise between genders, therefore males and females would be required to be separated into 2 different groups. As 20 participants of each group will need to be recruited to generate a reliable sCT atlas, 40 patients will be recruited to the study; 20 male patients and 20 female patients. Assuming the dose difference at the representative voxel is 1.5% (based on content knowledge and prior experience), a sample of 20 participants, each with a CT and sCT, will enable estimation of the mean percentage dose difference and 95% confidence interval with a 0.7% (absolute) margin of error.

Summary
Brief summary

The aim of this study is to evaluate the feasibility of MRI only planning for rectal, anal canal and gynaecological cancer radiation therapy. 

Who is it for?
You may be eligible to join this study if you are aged 18 years or over and have a histological diagnosis of a malignancy of the rectum, anal canal, cervix or endometrium and are about to be treated definitively with radical Radiotherapy at Calvary Mater Newcastle. 

Study details
All participants enrolled into this study will receive an additional MRI scan at the Diagnostic Imaging Department, Calvary Mater Newcastle, scheduled on the same day as the participants planning CT scan. There will be no change to the participant’s treatment in this study – they will receive the gold standard of care and treatment as per departmental protocols. The MRI scan will be used for comparative purposes only.
The MRI will be used to create a "synthetic CT scan" which will be used prospectively to compare to the participants previously acquired CT scan.

The use of MRI alone for radiotherapy planning will eliminate the potential inaccuracies in the current fusion process between the MRI and CT scan. This method has the potential to improve radiotherapy planning techniques by better utilising the superior soft tissue contrast that MRI affords.
