Ask Dr. Z

Dr Z, Hello, I have a client that checks vascular catheter patency using radionuclide in Nuc Med department. History:Left neck pain with flushing port-a-cath "Immediately after radionuclide injection images were obtained at 2-second intervals during the radionuclide phase. During the first 8 seconds, the port-a-cath was not opacified. radionuclide promptly opacifies at 10 seconds. The superior venacava is patent. Radionuclide promptly opacifies the right atrium, right ventricle, pulmonary outflow tract and lungs. Impression: no reflux into the left internal jugular vein was seen. I appreciate any suggestions, Judy
