The ability of 67Ga scintigraphy to detect Trichinella spiralis

To assess the value of (67) Ga scintigraphy in the lesions of Trichinella spiralis, an animal model was developed. Three infected and five healthy animals were enrolled in this study. After the injection of 7.4 MBq (200 micro Ci) (67) Ga citrate intravenously, static images from whole body were obtained at 24(th), 48 (th) and 72 (nd) hours Visual and semiquantitative analyses were performed. In semiquantitative analysis, activity counts were calculated over the whole body, diaphragm, neck muscles and extremities muscles of all animals. Between the infected animals and control group, mean bodies activity ratios were compared as visually and statistically. (67) Ga scintigraphy can't successfully demonstrate the lesions of Trichinella spiralis.
