Why the study?
The implications of lateral patient position on radiofrequency-induced heating of active and passive implantable medical devices in a wide-bore 3T MRI system were unknown.
Does lateral patient position affect RF-induced heating of implantable medical devices during 3T MRI?
Population
Three commercially available AIMDs and four orthopedic PIMDs in human body models and phantoms
Comparison
Different lateral phantom shifts and patient positions inside a wide-bore 3T MRI scanner
Design
In vitro simulation and experimental validation study

Lateral positioning may increase peripheral device heating risk in 3T MRI; leaves open human validation of position-specific safety.
Does lateral patient position affect RF-induced heating of implantable medical devices during 3T MRI?
Lateral patient positioning in wide-bore 3T MRI scanners can significantly increase RF-induced heating of implantable medical devices, particularly peripheral ones, impacting MR conditional labeling.
