PROBLEM TO BE SOLVED: To provide a catheter for imaging and an image diagnostic apparatus which can identify a structure of a blood vascular system to the same degree as a case in which a contrast medium is administered, without pouring the contrast medium in blood.SOLUTION: A catheter for imaging includes a catheter body and a plurality of linear objects. The catheter body consists of a hollow member. The linear object consists of a slender and flexible member in which at least a part has low X-ray permeability, and is configured so as to be able to protrude from the tip of the catheter body.COPYRIGHT: (C)2015,JPO&INPIT【課題】造影剤を血液中に流してしまわないで、かつ、血管系の構造を造影剤を投与したのと同等程度の識別できるようにする造影用カテーテルおよび画像診断装置を提供する。【解決手段】実施形態の造影用カテーテルは、カテーテル本体と複数本の線状体とを有する。カテーテル本体は中空部材で構成される。線状体は、細長く、柔軟で、少なくとも一部がX線透過性の低い部材で構成され、前記カテーテル本体の先端から突出可能に構成される。【選択図】図2
