99Tcm nanocolloid scintigraphy: a reliable way to detect active joint disease in patients with peripheral joint pain
2001
We evaluated 99 Tc m nanocolloid (NC) scintigraphy as a method for identifying patients with active joint disease in a group with peripheral joint pain of varying aetiology. Fifty-nine patients with peripheral joint pain were divided into two groups: those with clinical signs of active joint inflammation and those without objective signs. Thirty-four patients clinically diagnosed as having active joint disease had a total of 117 joints (95 large and 22 small) involved. 99Tcm NC identified 96 (79 large and 17 small) of these joints. Twenty-five patients were negative clinically. Twenty-two of these were scan negative. The other three had a total of 11 scan positive joints. The correlation coefficient between clinical and scan findings was 0.79. There was no significant difference shown between clinical evaluation and scintigraphy (z = -1.64, p 0.1004). 99 Tc m NC proved to be an effective method for identifying patients with active peripheral joint disease from among a group with arthralgia.
