Abstract
OBJECTIVE- To assess the new quantitative bone scan parameters as markers of Charcot neuroosteoarthropathy (CNO) activity. RESEARCH DESIGN AND METHODS - Forty-two patients With acute (n = 2 1) and nonacute (n = 21) CNO underwent quantitative bone scanning.
Patients With acute CNO were followed for 3-12 months and bone scans were repeated after treatment. New quantitative parameters were assessed and compared with markers of bone turnover and with skin temperature difference (STD).
RESULTS- Significant correlations between quantitative bone scan parameters and bone turnover markers were observed (all P < 0.05). These parameters decreased after treatment of CNO, and its reduction to the baseline Value correlated with differences of bone turnover markers and STD (all P < 0.05).
CONCLUSIONS - Our study suggests that bone scanning can be used not only for diagnosis of CNO but also for monitoring disease activity by quantitative bone scan parameters.
