Role of Radiological Assessment and Intervention in Pediatric Dialysis

Children on hemodialysis or peritoneal dialysis frequently need radiological assessment of dialysis access placement and patency. In many cases, radiological interventions can assist with the creation and maintenance of dialysis access. For these purposes, contrast media facilitate the interpretation of medical imaging by increasing the differences seen between body tissues displayed on the images. The contrast media used in diagnostic imaging and interventions have evolved over the decades. This chapter discusses the different roles that radiologic assessment and interventions, via contrast agents, play in dialysis, along with the current challenges.
