Figures
- FIGURE 1.
(A) Relationship between dispensed activity and injected activity of 99mTc-sestamibi in 216 patient procedures performed with brand A syringes. (B) Histogram showing distribution of residual activity in syringes and infusion sets used in 216 procedures.
- FIGURE 2.
Correlation between percentage residual activity in patient syringe (rinsed 3 times with saline) and percentage residual activity in sham syringe (no rinsing) that was prepared under identical conditions to patient syringe.
- FIGURE 3.
Effect of up to 15 prerinses on cumulative residual activity in brand A (both with and without prior wash in acetone) and brand F syringes.
- FIGURE 4.
γ-camera image of 2 brand A syringes. Syringe on left was used to draw up 1 mL of 99mTc-sestamibi solution. Syringe on right was dipped in same 99mTc solution up to top of barrel. Both syringes were then emptied and rinsed with water.
- FIGURE 5.
(A) Relationship between dispensed activity and injected activity of 99mTc-sestamibi in brand A syringes (73 procedures) and brand F syringes (50 procedures). (B) Histogram showing distribution of residual activity in brand A and brand F syringes.
