Abstract

The purpose of this study was to examine the usefulness of IDEAL technique in breast MRI by performing a quantitative comparative analysis in patients diagnosed with DCIS. On a 3.0T MR scanner, fat-suppressed T2-weighted images and T1-weighted images before and after contrast enhancement were obtained from 20 patients histologically diagnosed with ductal carcinoma in situ (DCIS). The findings from the quantitative image analysis are the following: 1) On T2-weighted images, SNR were not significantly different in the lesion area itself between the CHESS and IDEAL groups, while the IDEAL group showed higher SNR at the ductal area and fat area than the CHESS group. In addition, the CNR were higher for the IDEAL group in those regions. 2) On T1-weighted images before enhancement, SNR were not significantly different in the lesion area itself between the CHESS and IDEAL groups, while the IDEAL group showed higher SNR at the ductal area and fat area than the CHESS group. In addition, the CNR were higher for the IDEAL group in those regions. 3) On T1-weighted images after enhancement, SNR were not significantly different in the lesion area itself between the CHESS and IDEAL groups, while the IDEAL group showed higher SNR at the ductal area and fat area than the CHESS group.

유방암중 관상피내암으로 진단 받은 환자를 대상으로 기존의 지방 억제 기법인 CHESS와 새로운 기법인 IDEAL을 정량적으로 비교 분석하여 IDEAL기법의 효과와 유용성을 고찰 해보고자 한다. 조직학적으로 관상피 내암으로 진단 받은 환자 20명을 대상으로 3.0T MR scanner를 이용하여 CHESS 기법과 IDEAL 기법을 이용하여 지방 억제한 횡이완 강조 영상과 조영 증강 전후의 종이완 강조 영상을 획득하였다. 분석 결과 횡이완 강조 영상과 조영 증강 전, 후의 종이완 강조 영상에서 신호대 잡음비는 병변 부위에서는 차이를 보이지 않는 반면 유관조직과 지방조직에서는 IDEAL 기법을 이용한 그룹에서 높은 신호대 잡음비를 보였으며 두 그룹에서의 대조도대 잡음비는 IDEAL 기법을 이용한 그룹에서 높은 대조도대 잡음비를 보였다.
