Abstract

The purpose of this study was to examine the usefulness of diffusion weighted images in breast MRI by performing a quantitative comparative analysis in patients diagnosed with DCIS. On a 3.0T MR scanner, diffusion weighted images and ADC map images were obtained from 20 patients histologically diagnosed with ductal carcinoma in situ (DCIS). The findings from the quantitative image analysis are the following: The diffusion weighted images showed higher SNR and CNR at the lesion area. In addition, the ADC values were lower at the lesion area.

유방암중 관상피 내암으로 진단 받은 환자를 대상으로 확산강조 영상을 정량적으로 비교 분석하여 확산강조영상의 효과와 유용성을 고찰 해보고자 한다. 조직학적으로 관상피 내암으로 진단 받은 환자 20명을 대상으로 3.0T MR scanner를 이용하여 확산강조영상과 ADC map 영상을 획득하였다. 정량적 분석 결과 병변 부위와 정상부위의 신호대 잡음비와 대조도대 잡음비는 병변 조직에서 높은 신호대 잡음비와 대조도대 잡음비를 보였으며 병변 부위와 정상부위의 현성확산계수는 병변 조직에서 낮은 현성확산계수를 보였다.
