Summary:The present invention relates to an RF coil for magnetic resonance imaging (MRI) to measure a molar concentration of a specific nuclide by using a magnetic field outside the coil. The RF coil for magnetic resonance imaging comprises: one pair of end rings (110) disposed on the same axis (C); and a plurality of legs (120) connecting the end rings (110) to each other. The leg (120) comprises a first leg element (121) connecting the end rings (110) to each other at an outer diameter of the end rings (110) and a second leg element (122) which is electrically insulated from the first leg element (121) to form a closed shell together with the first leg element (121), and in which a phantom (2) is disposed, so that each of the legs (120) constitutes a resonance circuit. 본 발명은 코일 외부의 자기장을 이용하여 특정 핵종의 몰농도를 측정하기 위한 자기공명영상용 RF 코일에 관한 것으로, 동일 축(C) 상에 배치되는 한 쌍의 엔드링(110)과, 상기 엔드링(110)을 서로 연결하는 복수 개의 레그(120)를 포함하는 자기공명 영상용 RF 코일에 있어서, 상기 레그(120)는, 상기 엔드링(110)의 외경 측에서 상기 엔드링(110)을 서로 연결하는 제1레그 엘리먼트(121)와; 상기 제1레그 엘리먼트(121)와 전기적으로 절연되어 상기 제1레그 엘리먼트(121)와 함께 폐각(closed shell)을 구성하여 그 내부에 팬텀(2)이 배치되는 제2레그 엘리먼트(122)를 포함하여 상기 레그(120) 각각은 공진 회로를 구성한다.
