Peter, who was diagnosed with cancer at Barts but because of his pacemaker – which had been implanted at another hospital – struggled to get an MRI. Instead of undergoing MRI, he initially underwent an attempt at extracting the pacemaker. This is a major procedure which carries a risk of mortality. This was only partly successful as part of the lead was left abandoned in the heart, which then increased his risk of future MRI.  Thanks to the MRI service, scans were planned carefully for him. He was able to undergo multiple scans which were needed for his treatment with surgery and radiotherapy. He has kindly agreed to post this (as both a patient and a Barts Charity ambassador) so that we as clinicians drive more service availability across the country.
