Abstract
Image guided puncture is one of the most fundamental techniques among many procedures that interventional radiologists should acquire. While the diversification of the techniques is accelerating, it usually depends on the skill and judgment of individual operators. Basically, the operators should know the characteristics of needles and acquire the skill and the sense of manipulating each needle with their own hands delicately. To that end, it is important that the attitude of continuing to refine their skills in daily practice, and as a result of that, it will be possible to achieve maximum results with minimal invasion. We report biliary intervention, radiofrequency ablation (RFA) and percutaneous drainage from the viewpoint of how to lead to success at sites considered to be difficult to puncture.
