Power Doppler sonography: synovial tissue assessment in RA

Unfortunately, Carotti et al did not provide any data on the sensitivity and specificity of the method used. [...]no figure showing distribution of the vascularisation scores in individual patients and/or confidence limits of the mean was available. [...]the implementation of microinjection devices that are currently being studied may decrease the required dose of contrast medium, and this should reduce overall examination time and the cost of ultrasound contrast agent for each patient.
