MRI of the claustrophobic patient: interventionally configured magnets.
The aim of this study was to determine whether or not claustrophobic patients would tolerate a scan in an open configuration interventional magnetic resonance (iMR) imaging unit, when they had failed to complete a diagnostic scan in a conventional MRI system. 50 claustrophobic subjects were entered into the study. Their response to the iMR environment was compared with their previous experience in an MRI scanner by means of a two-stage questionnaire. Part 1 was completed before their iMR scan and Part 2 following their attempt at imaging in the iMR unit. 60% (n = 30) of the participants were female and 40% (n = 20) were male, age range 25-71 years (mean 49.5 years). 48% (n = 24) were lumbar spine studies and 28% (n = 14) were studies of the head. 24% (n = 12) underwent scanning of other anatomical regions. 94% (n = 47) of participants underwent successful MRI in the interventional magnet without extra sedation. 6% (n = 3) failed to complete a diagnostic scan in the iMR machine. The GE Signa 0.5 T SP magnet allows successful MRI in 94% of the claustrophobic population who have failed to complete a scan in a conventional diagnostic machine.
