- Background: Cardiovascular magnetic resonance imaging (CMR) and myocardial perfusion scintigraphy (MPS) are two technically advanced methods for imaging cardiac diseases. Although CMR is considered to be painless, considerable patient cooperation is necessary during scanning. Some patients may experience anxiety because of the closed environment of the procedure.The aims of this paper were to evaluate the potential effect on patient anxiety and on motion artefacts by adding a 5 min video sequence to the standard written information given before CMR. Additionally, the patient experience of CMR was compared to that of MPS.Methods: The sample (n=146) consisted of 97 patients randomized to receive either video information in addition to standard written information (CMR-video/n=49) or standard written information alone (CMR-standard/n=48). A third group undergoing MPS (n=51) was used to compare CMR-standard and MPS. Anxiety was evaluated before, immediately after the procedure and one week later. Four questionnaires were used: State-Trait-Anxiety Inventory, Hospital-Anxiety and Depression-scale, MRI-Fear-Survey-Schedule and the MRI-Anxiety-Questionnaire (MRI-AQ). Motion artefacts were evaluated by three observers, blinded to the information given. Motion artefacts due to arrhythmia were not considered.Results: Measured with MRI-AQ, the CMR-video and the CMR-standard groups did not score significantly different on the factor Anxiety. However, CMR-video scored lower (=better) in the factor Relaxation (p=0.039). Younger patients and women scored a higher level of anxiety in most scales. Anxiety levels (MRI-AQ) were lower during MPS examinations compared to the CMRstandard group (p < 0.001 ). The presence of motion artefacts was similar in the CMR-video compared to the CMR-standard group.Conclusions: Patient ability to relax during CMR increased by adding video information prior to the exam. This positive effect on patient experience is important to enable technologists to obtain full patient cooperation. An apparent lack of effect on motion artefact could possibly be due to the addition of compensatory extra scans when a low image quality was recognized by the technologists.
