|
The purpose of this study is to evaluate the safety of the breast tissue expander implanted patients who require MRI examination. Torques were 0ml, 150 ml, 300 ml, 450 ml at 1.5 Tesla forward direction, 4, 3, 3, and 2 respectively, and 1.5 Tesla reverse direction at 4, 4, 4, 3 respectively. In the 3.0 T environment, 4 was shown in all conditions. In the overturning experiment, no overturning occurred in more than 300 ml in the 1.5Tesla environment, and most of the overturning occurred in the 3.0 Tesla environment. In terms of safety, MRI scans of patients with breast tissue expanders should be avoided at 3.0 Tesla and conditionally at 1.5 Tesla.
