Numerical assessment of asymmetry at scintigraphy of normal joint pairs with (99)Tcm polyphosphate

Numerical analysis of (99)Tcm polyphosphate distribution in 1 348 selected, non-pathologic joint pairs revealed a significantly higher right-sided accumulation in 37 per cent, a left-sided dominance in 21 per cent and no significant side difference in the remaining 42 per cent. The most common level of asymmetry was the shoulder joint.
