of motion sickness was present in 75% (simulation) and 37% (imaging) of all subjects, however the mean motion sickness scores over all rotations were 3.5% (simulation) and 6.76% (imaging) indicating a good tolerance of the PRS for most subjects. In detail the symptom strength of the subclasses was not the same for imaging and simulation. The greatest discrepancy occurred for peripheral symptoms like cold-sweatiness, sweatiness and heat (imaging: 18.63%; simulation: 52%). Presumably, this is due to the ambient temperatures present at time of study participation (simulation mostly in late spring; imaging mainly in winter). The gastro-intestinal symptoms (imaging: 14.14%; simulation: 12.6%) and the central symptom (imaging: 8.63%; simulation: 7.83%) were less prominent and similar for both simulation and imaging. Anxiety was comparable for both parts of the study and comparable to regular resonance-imaging examination without a rotation system.

Conclusion:

Magnetic resonance-imaging in a fully-enclosed patient-rotation-system was shown to be feasible for the investigated subjects. In order to further develop the system, the air circulation within the system should be increased, in order to reduce heat build-up. Also the general comfort should be increased. The anxiety scores showed similar levels as for regular MRI.
