유방 조직 확장기의 1.5T와 3.0T MRI 환경 내 안정성 평가 = Evaluation of MR Safety of Breast Expander on 1.5T and 3.0T MRI

다국어 초록 (Multilingual Abstract)

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.

MRI 검사가 필요한 유방조직확장기 삽입 환자에 대해 체내 안전성을 평가하고자한다. 토크는 1.5 T 정방향 진입 시 0 ml, 150 ml, 300 ml, 450 ml 각각 4, 3, 3, 2이었고, 1.5 T 역방향 진입 시 각각 4, 4, 4, 3이었다. 3.0 T 환경에서는 모든 조건에서 4를 나타냈다. 뒤집힘 실험은 1.5 T 환경에서 300 ml 이상에서 뒤집힘이 발생하지 않았고, 3.0 T 환경에서는 대부분 뒤집힘이 발생하였다. 유방조직확장기 삽입 환자의 MRI 검사는 안전성 측면에서는 3.0 T는 피하고 1.5 T에서 조건부로 가능하다.
