Abstract

Purpose: Establishment of an appropriate protocol for breast magnetic resonance imaging (MRI) in the study of image quality standards to enhance the effectiveness of medical image information exchange, which is part of the construction and activation of clinical information exchange for healthcare informatization. Materials and Methods: The recommended protocols of breast and MRI scans were reviewed and the questionnaire was prepared by a responsible researcher. Then, a panel of 9 breast dedicated radiologists was set up in Korea. The expert panel conducted a total of three Delphi agreements to draw up a consensus on the breast MRI protocol. Results: The agreed breast MRI recommendation protocol is a 1.5 Tesla or higher device that acquires images with prone position using a breast dedicated coil and includes T2-weighted and pre-contrast T1-weighted images. Contrast enhancement images are acquired at least two times, and include 60-120 seconds between images and after 4 minutes. The contrast enhancement T1-weighted image should be less than 3 mm in thickness, less than 120 seconds in temporal resolution, and less than $1.5mm^2$ in-plane pixel resolution. Conclusion: The Delphi agreement of the domestic breast imaging specialist group has established the recommendation protocol of the effective breast MRI.

목적: 보건의료정보화를 위한 진료정보교류 기반 구축 및 활성화 과제의 일부인 의료영상정보교류의 효용성을 높이기 위한 영상 품질 기준 연구에서 유방 자기공명영상검사의 적절한 프로토콜을 정립한다. 대상과 방법: 문헌 및 참고자료를 통한 국내외 유방 자기공명영상검사의 권고 프로토콜과 판독문 형식을 조사하고, 책임연구자가 설문지를 작성한 후, 국내 9명의 유방영상의학 전문가를 섭외하여 패널을 구성하였다. 전문가 패널은 총 3차례의 델파이 합의를 진행하여 유방자기공명영상 프로토콜의 합의안을 도출하였다. 결과: 합의된 유방자기공명영상 권고 프로토콜은 1.5 테슬라 이상의 기기로 유방 전용 코일을 사용하여 복와위 자세에서 영상을 획득하며, T2 강조영상과 조영 전 T1 강조영상을 포함한다. 조영증강영상은 적어도 2차례 이상 획득하며, 60~120초 사이 영상과 4분 이후 영상을 포함한다. 또한 조영증강 T1 강조영상의 절편 두께는 3 mm 이하, 측면 해상력은 120초 이하, 공간 내 평면 해상도는 $1.5mm^2$ 이하여야 한다. 결론: 국내 유방영상전문가 집단의 3차례에 걸친 델파이 합의를 통하여 효율적인 유방 자기공명영상검사의 검사 프로토콜 권고안을 정립하였다.
