PROBLEM TO BE SOLVED: To provide an intracorporeal lumen-imaging multilayer coil type MRI (Magnetic Resonance Imaging) probe having a reception coil of an NMR signal, allowing imaging of a lesion difficult to be imaged with a normal MRI apparatus from the inside of the body by mounting the reception coil at the tip of a catheter or an endoscope and leading it into a blood vessel or a digestive tract in a deep part inside the body, and allowing high-resolution drawing of the blood vessel or the digestive tract in the deep part inside the body to achieve preventive diagnosis of a disease.SOLUTION: An MRI reception coil is formed with at least a coil part 32 on a small-diameter tube 31. A part of wiring of one loop forming the coil part is formed with a projecting part 35 projecting on a distal side in the axial direction of the tube or a recessed part recessed on a proximal side in the axial direction of the tube.COPYRIGHT: (C)2014,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
