  • Title: Color Doppler twinkling artifacts in small-bowel bezoars.
    Author: Kim HC, Yang DM, Kim SW, Park SJ, Ryu JK.
    Journal: J Ultrasound Med; 2012 May; 31(5):793-7. PubMed ID: 22535727.
    Abstract:
    Small-bowel bezoars usually form in the stomach and may subsequently cause small-bowel obstruction. Bezoars associated with small-bowel obstruction have been accurately diagnosed by computed tomography, although some case reports have described the specific sonographic findings of small-bowel bezoars. Bezoars can be overlooked by sonographic examination if a dilated small-bowel loop contains a large amount of air. Twinkling artifacts on color Doppler images appear as rapidly fluctuating red and blue signals behind certain strongly reflecting structures. In this series, we hypothesize that twinkling artifacts might appear in small-bowel bezoars, and we describe the presence of twinkling artifacts in 3 cases of small-bowel bezoars presenting as small-bowel obstruction.
