Preferred scanner design for future scanner development depending on the presence of a claustrophobic event

Preferred scanner design for future development	In patients without a claustrophobic event after MRI		In patients with a claustrophobic event after MRI		Change in preferences depending on the presence of a claustrophobic event
					p = 0.047 ***
	n = 116	95% CI	n = 44	95% CI
A: Open panoramic scanner, n (%)	36 (31.0)	23.3–39.9	17 (38.7)	25.7–53.4
B: Short-bore scanner, n (%)	23 (19.8)	13.6–28	3 (6.8)	2.3–18.2
C: Open one-column scanner, n (%)	19 (16.4)	10.7–24.2	3 (6.8)	2.3–18.2
D: Upright open scanner, n (%)	38 (32.8)	24.9–41.7	21 (47.7)	33.8–62.1

Patients who experienced a claustrophobic event directly before completing the questionnaire preferred an upright open scanner and open panoramic design significantly more often than a short-bore design. The change in difference depending on the presence of a claustrophobic event was statistically significant (p = 0.047)
