Methods Greyscale imagi g a d blood flow of the sy ovial membra e were studied by highfreque cy grey scale, color Doppler flow imagi g, color Doppler e ergy a d pulsed w ave Doppler i 43 patie ts ( 86 k ee joi ts) w ith rhe matoid arthritis ( RA) . Results The thick ess of the sy ovial membra e was i creased i 83 joi ts ( 96. 51% , 2. 2~ 17. 3 mm) , the sy ovial membra e w as furrowed a d fuzzy a d sy ovial villi were ma ifested i most cases. Low velocity mode CDFI a d CDE revealed blood flow i 68 k ee ( 81. 92%) i proportio to the thick ess of sy ovial membra e. CDE i creased the positive rate of blood flow display a d showed much more vascular bra ch tha CDFI did. Artery blood Vmax, Vmi a d RI w ere ( 11.76 3. 68) cm/ s, ( 4. 68 1. 62) cm/ s a d ( 0. 63 0.05) recorded by pulsed w ave Doppler. Vmea of vei was ( 4. 37 1. 03) cm/ s. Conclusions Highfreque cy ultraso ography is a o i vasive a d se sit ive method to reveal fu dame tal pathological alteratio of sy ovial membra e i rheumatoid k
