Beck MC, et al. - The researchers performed a comparative evaluation of the fluorescence optical imaging (FOI) with ultrasonography (US), by gray-scale (GS) and power Doppler (PD)) and clinical examination (CE). It also aimed at computing the predictive power of FOI for the discrimination between inflammatory and non-inflammatory juvenile joint diseases. A moderate to good agreement was disclosed of the FOI with CE and US based on the phase evaluated. Limitation prevailed in both the imaging methods and hence ought to be interpreted cautiously. FOI could present as an additional diagnostic method in pediatric rheumatology.
