Last year in the UK over 60,000 cancer patients enrolled on clinical trials aimed at improving cancer treatments and making them available to all.
A study looking at PET-MRI scans for people with head and neck cancer
This study used a combined PET and MRI scan to help plan radiotherapy for people with head and neck cancer. It was for people with squamous cell carcinoma of their mouth or throat.
The study was open for people to join between 2016 and 2018. The research team presented the results at a conference in 2018.
More about this trial
Doctors often treat head and neck cancers with radiotherapy.
When this trial was done, people usually had a CT scan before they had radiotherapy. This was to show the size and position of the cancer. It helps doctors plan the area to treat and the dose of radiotherapy to use.
In this study, researchers looked at using PET-MRI scans as well as CT scans. They hoped these scans would give clearer pictures so doctors could plan radiotherapy even more accurately.
When people have radiotherapy for head and neck cancer, they wear a specially made plastic mask that is moulded to the shape of their head. This is sometimes called a shell. It is to help them stay still during treatment, so the radiotherapy treats the exact area of cancer.
The research team wanted to find out what people thought about having a PET-MRI scan while wearing their radiotherapy mask.
The main aims of this study were to find out:
- the best way to do a combined PET and MRI scan (the scanning protocol)
- if it is possible for people to have a PET-MRI scan with a radiotherapy mask on
Summary of results
This study was for people with advanced head and neck cancer who were due to have radiotherapy. They had PET-MRI scans before and during their course of radiotherapy.
A total of 6 people took part.
The research team found that PET-MRI scans could be useful to help plan radiotherapy for people with head and neck cancer. And that they could be done in 30 minutes or less. Most people found it ok to have a scan while they had their radiotherapy mask on.
