US images were used to determine the glottic angles. During MRI two dynamic sequences, fast field echo and balanced gradient echo, were applied to determine the minimum and maximum values of the glottic angles, along with the rima glottidis area, separately for the right and left compartments. Due to differences in larynx anatomy, the abovementioned parameters were analysed separately for women and men.<\/jats:p><\/jats:sec>Results<\/jats:title>No significant differences were observed between the glottic angle values obtained during US and dynamic MRI (FFE and TRUFI sequences). Regardless of the dynamic MRI sequence used, a\u00a0positive correlation was found between the maximum values of glottic angle and the rima glottidis area. This correlation was strong and statistically significant among men, but not in women.<\/jats:p><\/jats:sec>Conclusions<\/jats:title>Dynamic MRI of vocal folds using FFE and TRUFI sequence is an accurate method for the objective evaluation of rima glottidis width.<\/jats:p><\/jats:sec>","DOI":"10.5114\/pjr.2019.89122","type":"journal-article","created":{"date-parts":[[2019,11,5]],"date-time":"2019-11-05T09:21:00Z","timestamp":1572945660000},"page":"368-374","source":"Crossref","is-referenced-by-count":10,"title":["Assessment of vocal fold mobility using dynamic magnetic resonance imaging and ultrasound in healthy volunteers"],"prefix":"10.5114","volume":"84","author":[{"given":"Magdalena","family":"Derlatka-Kochel","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pawel","family":"Kumoniewski","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marcin","family":"Majos","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kamil","family":"Ludwisiak","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lech","family":"Pomorski","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Agata","family":"Majos","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"3061","published-online":{"date-parts":[[2019,9,25]]},"reference":[{"key":"ref-1139892","doi-asserted-by":"crossref","first-page":"178","DOI":"10.1097\/01.mlg.0000150701.46377.df","article-title":"Endoscopic measurement of vocal fold movement during adduction and abduction","volume":"115","author":"Dailey SH","year":"2005","unstructured":"Dailey SH, Kobler JB, Hillman RE, et al.
