Dynamic Doppler evaluation of the hand arteries to distinguish between primary and secondary raynaud phenomenon.


OBJECTIVE The objective of our study was to use Doppler sonography to detect the flow characteristics and parameters of the hand arteries that are needed to distinguish between primary Raynaud phenomenon (RP) and secondary RP. SUBJECTS AND METHODS The diameter, resistive index (RI), and flow volume of the digital, ulnar, and radial arteries of patients… (More)
