Steady state venography using 195m-gold
The introduction of 195m-Au has provided a useful non-diffusible, short T1/2 isotope (30 seconds) for cardiac and vascular work. The authors have investigated its use as an imaging agent for the deep venous circulation of the legs comparing its results with conventional contrast venography and a routine radioisotope method using 99mTc-MAA. The 195m-Au Generator is steadily eluted using a constant perfusion pump at 10cc/minute. The eluant was delivered into a superficial leg vein using a catheter (1.5mm Cook PVC) and 19G butterfly needle. Bilateral venograms were performed using a ''Y'' divider. Owing to the very short T1/2 recirculation activity was not seen and the images gave a clean picture of the lower limb venous circulation extending up to the inferior vena cava.
