Why the study?
Are 32 previously unevaluated heart valve prostheses safe for use in a 1.5-T MRI environment?
Are 32 previously unevaluated heart valve prostheses safe for use in a 1.5-T MRI environment?
Ex vivo testing of 32 heart valve prostheses demonstrates they are safe for MRI procedures at 1.5 Tesla or less, with negligible heating and minor magnetic field interactions.

Supports conditional 1.5-T MRI labeling; extends ex vivo data but leaves open in vivo confirmation before clinical adoption.
Edwards et al. (2000) studied this question.
