In some cases, however, B\u2010mode ultrasonography can be inconclusive. We investigated whether color Doppler imaging can significantly improve vocal cord examination in these cases.<\/jats:p><jats:p><jats:italic>Method.<\/jats:italic> Ten normal volunteers were examined using the Acuson 128XP\/5 with a 7\u2010MHz L7384 linear transducer. The thyroid cartilage was used as an acoustic window. Several distinct color flow patterns were observed with the subjects breathing quietly at rest, at the start of vocalization, and in prolonged phonation. Eight patients with hoarseness of voice were then examined by two separate observers in a double\u2010blinded fashion. The first observer performed B\u2010mode ultrasonography and color Doppler imaging, while the second observer performed indirect laryngoscopy and direct fiberoptic laryngoscopy.<\/jats:p><jats:p><jats:italic>Results.<\/jats:italic> Laryngoscopy was used as the standard for comparison. B\u2010mode real\u2010time ultrasonography correctly identified vocal cord palsy in three patients and normal vocal cords in one. The remaining four patients were reported as equivocal or normal. Color Doppler imaging correctly identified the problem in all eight patients.<\/jats:p><jats:p><jats:italic>Conclusion.<\/jats:italic> Color Doppler imaging for vocal cord examination is more sensitive than B\u2010mode real\u2010time ultrasonography, and seems to be as accurate as laryngoscopy in determining vocal cord palsy or paresis. \u00a9 1995 Jons Wiley &amp; Sons, Inc.<\/jats:p>","DOI":"10.1002\/hed.2880170105","type":"journal-article","created":{"date-parts":[[2007,2,21]],"date-time":"2007-02-21T22:43:21Z","timestamp":1172097801000},"page":"20-23","source":"Crossref","is-referenced-by-count":29,"title":["Color doppler imaging for vocal cord palsy"],"prefix":"10.1002","volume":"17","author":[{"given":"London Lucien P.
