RT Journal Article SR Electronic T1 Central Venous Catheter Scintigraphy Using a Slow Radionuclide Infusion: Case Report JF Journal of Nuclear Medicine Technology JO J. Nucl. Med. Technol. FD Society of Nuclear Medicine SP 245 OP 247 VO 18 IS 4 A1 Jacobson, Arnold F. A1 Williams, Walter H. YR 1990 UL http://tech.snmjournals.org/content/18/4/245.abstract AB Radiologic investigation of malfunctioning central venous catheters is conventionally performed using a bolus injection of either radiographic contrast material or a radionuclide solution. An alternative scintigraphic technique employing a slow radionuclide infusion is described. The association between retrograde flow in an obstructing fibrin sleeve and leakage from a central venous catheter is better demonstrated using this technique than with imaging after a bolus injection.
