Visualization of Dialysis Fistula by Computed Tomography Using Time-Resolved 3D Volume Rendering
چکیده انگلیسی

BackgroundTo evaluate the function of arteriovenous (AV) dialysis fistula using dynamic computed tomography (CT) and time-resolved 3-dimensional (3D) volume rendering (VR).MethodsSeven patients referred for angiographic CT examination of the AV dialysis fistula were enrolled. Twenty-four grams of iodine were administered intravenously (iomeprol 400 mg I/mL at 6 mL/sec) followed by a 50-mL saline flush. Dynamic scanning was performed for 15–24 sec. CT images were then postprocessed on a dedicated workstation creating time-resolved 3D VR images and movies.ResultsAll studies showed good image quality showing pathology in 6 of 7 patients. Unexpected findings were observed in 1 patient, aneurysm (n = 1). Radiation dose was 5 mSv.ConclusionsThe function of AV dialysis fistula can be visualized using dynamic CT and time-resolved 3D VR.
