- Abstract
Objective To apply a simple fixator to salivary gland scintigraphy to evaluate its effect on body position movement. Methods Totally 30 female patients complaining xerostomia were randomly and equally divided into a conventional scan group and a simple fixator group, who were injected with Technetium Tc-99m Pertechnetate intravenously. In the conventional scan group the patients had their necks fixed with the bracket and cushion, while in the other group the fixation was executed with the single fixator. SPECT imager was used for dynamic salivary gland scintigraphy, and two nuclear medicine physicians evaluated the maximum shift of the parotid gland along left-right (X) and head-foot (Y) axes in series of dynamic images. SPSS 16.0 software was used for data analysis. In the conventional scan group the maximum shift was(6.6±4.6)mm at X axis and(5.2±3.4)mm at Y axis;in the single fixator group the maximum shift was(3.2土 1.6)mm at X axis and(3.0±1.3)mm at Y axis.Thereweresignificantdifferencesbetweenthemaximumshiftsinthetwogroups (P=0.012, X axis; P=0.027, Y axis). Conclusion The single fixator assists in salivary gland scintigraphy, and alleviates the body position movement during dynamic acquisition and provides data support for functional parameter calculation and result determination.
