Abstract:
Objective To comparatively study the differences of 18F‐FDG imaging agent by three kinds of different intravenous injection method for conducting PET / CT examination in aspects of the puncture success rate ,residual amount of drug injection and staff ray exposure time and their significance .Methods 240 patients with PET /CT examination were randomly divided into the group A ,B and C ,80 cases in each group .The drug injection adopted the traditional direct injection ,indwelling catheter injection and scalp venous needle connecting syringe(indwelling bubbles) .The puncture success rate ,drug residues and staff contacting radio‐pharmaceuticals time were compared among 3 groups .The obtained relevant data were statistically analyzed .Results The puncture success rate in the scalp venous needle connecting syringe (indwelling bubbles) and the indwelling catheter injection was higher than that in the traditional direct injection and the staff contacting radiopharmaceuticals time was significantly decreased ,the differ‐ences among them were statistically significant(P< 0 .01) ;the radioactive drugs residue in the scalp venous needle connecting syr‐inge was significantly decreased than that in other two kinds of injection method ,the difference was statistically significant (P <0 .01) .Conclusion The injection method of scalp intravenous needle connecting syringe (indwelling bubbles) significantly increases the puncture success rate ,reduces the radioactive drug residue ,at the same time decreases the staff radiation exposure time ,this method has the advantage in the radionuclide injection .
