Abstract
Introduction: Magnetic resonance imaging (MRI) offers superior soft tissue contrast to computed tomography
(CT), the current standard imaging modality for planning radiotherapy treatment. Improved
soft tissue contrast could reduce uncertainties in identifying tumour and surrounding healthy tissues,
potentially leading to improved outcomes in patients with lung cancer. This study explored patient
experience of MR treatment planning scans in addition to a CT scan.
Methods: Participants were recruited to the 'Magnetic Resonance Imaging for the Delineation of Organs
At Risk and Target Volumes in Lung Cancer Patients (MR-Lung)' study at a UK specialist cancer centre.
Participants completed their standard of care radiotherapy planning CT scan and two additional MRI
scans. Baseline and post-scan questionnaires were completed assessing anxiety and claustrophobia.
Motion artefact during MRI was assessed by a modified visual grading analysis. Sixteen participants
completed semi-structured interviews; transcripts were analysed thematically.
Results: 29 people (66% female; aged 54e89 years) participated. Nineteen participants completed all
imaging and 10 participants withdrew before completion. There was minimal adverse impact on state
and scan-specific anxiety levels from completing the MRI scans. Completers experienced significantly
less scan-specific anxiety during MRI 1 compared to non-completers (U ¼ 33, z ¼ 1.98, p < 0.05). 78% of
those who withdrew during or post MRI 1 were positioned 'arms up'. Motion artefact negatively
impacted image quality in 34% of scans. Participants commonly reported concerns during MRI; noise,
claustrophobia and pain in upper limbs.
Conclusion: Two thirds of participants tolerated two additional MR scans with minimal adverse impact
on anxiety levels.
