Abstract [en]

Introduction: Magnetic resonance imaging in closed-bore scanners sometimes provokes anxiety but closed-bore designs have gradually become wider and shorter. Open scanners may be easier to tolerate. The aim was to compare patient anxiety during MRI between bore diameters of 60 cm and 70 cm, and to determine the current level of patient anxiety and experience in open scanners in a clinical setrting.

Methods: Consecutive patients referred for examination of the spine in 60 cm and 70 cm bores and one open scanner participated. Four established/validated questionnaires, answered before, directly after (N = 155) and one week after (N = 109) the MRI-examination were used, measuring anxiety, fear and depression.

Results: No difference was found in the patient scores of anxiety between the 60 cm and the 70 cm scanners on the examination day. At follow-up, patients in the 70 cm bore rated their examination experience better (p < 0.025), compared to patients in the 60 cm bore. Patients in the open scanner rated higher levels of anxiety (p < 0.001) before, directly after and one week after the examination, compared to the closed bore scanners.

Conclusion: Scanners with a 70 cm diameter bore seem more tolerable than those with a 60 cm bore. Patients referred to the open scanner had on average a higher tendency to express anxiety. Still, patient anxiety in MRI is challenging and further research required.

Implications for practice: Patients prefer to be examined in 70 cm bore scanners compared with 60 cm. If open scanners aren't available extended support may be necessary for the most anxious patients.
