PROBLEM TO BE SOLVED: To provide a multilayer coil type MRI (Magnetic Resonance Imaging) probe for imaging the lumen in the body which draws blood vessels and guts in the deep part of the living body in high resolution and attains predictive diagnosis of a disease by having a reception coil of an NMR signal, loading this at the tip of a catheter or an endoscope to be guided to the blood vessels and the guts in the deep part of the living body, so as to capture the image of a lesion the image of which is difficult to capture with a normal MRI apparatus, from inside of the living body.SOLUTION: The MRI receiving coil is obtained by forming at least a coil part 32 on a small-diameter tube 31. At a part of the wiring of a loop forming the coil part, a projecting part 35 projecting toward the distal side in the axial direction of the tube or a recessed part recessed in the proximal side in the axial direction of the tube is formed.COPYRIGHT: (C)2011,JPO&INPIT【課題】NMR信号の受信コイルを有しており、これをカテーテルや内視鏡の先端に搭載して体内深部の血管や消化管へ誘導することで、通常のMRI装置では撮像困難な病変を体内から撮像できるようになり、体内深部の血管や消化管を高分解能に描画し、病気の予防診断を実現する体内管腔撮像用多層コイル型MRIプローブを提供する。【解決手段】細径チューブ31上に少なくともコイル部32を形成したMRI受信コイルであって、コイル部を形成する1ループの配線の一部に、チューブの軸方向の遠位側に突出した凸部35又はチューブの軸方向の近位側に凹んだ凹部を形成した。【選択図】 図6
