Doppler sonography of perifibroid and intrafibroid arteries of uterine leiomyomas.

The predominant pattern of fibroid vascularity is peripheral vascularity and the perifibroid artery indices (except EDV and DAR) are significantly higher than those of the intrafibroid artery. Recurrent fibroids in women with previous myomectomy had significantly higher intrafibroid PI, RI, SDR, and ImI than those without previous myomectomy.
