His lifelong contributions to Doppler ultrasound fundamentally reshaped obstetric and gynecologic practice worldwide, with measurable impact on maternal and perinatal morbidity and mortality. From seminal work in uteroplacental and fetal circulation to pioneering applications of transvaginal color and three-dimensional Doppler imaging, Professor Kurjak\u2019s visionary leadership and mentorship established a global school of thought that transcended geographic, political, and economic boundaries. His achievements are particularly remarkable given that much of this transformative work originated in a small country, Croatia, yet profoundly influenced clinical practice across the world.<\/jats:p>","DOI":"10.1515\/jpm-2026-0088","type":"journal-article","created":{"date-parts":[[2026,4,10]],"date-time":"2026-04-10T02:38:47Z","timestamp":1775788727000},"page":"645-647","source":"Crossref","is-referenced-by-count":0,"title":["A lifetime of innovation, visionary leadership, and global mentorship in Doppler ultrasound: honoring professor Asim Kurjak"],"prefix":"10.1515","volume":"54","author":[{"given":"Ivica","family":"Zalud","sequence":"first","affiliation":[{"name":"ID50677 John A Burns School of Medicine, University of Hawai\u2019i , Honolulu , USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"374","published-online":{"date-parts":[[2026,4,8]]},"reference":[{"key":"2026050821281529740_j_jpm-2026-0088_ref_001","unstructured":"https:\/\/scholargps.com\/certificates?e_ref=7a2130ec4d6ed9ee7d49&id=93495166585780&c=5f2a6302a5e7627e99293137e2 2d0d1e87c655584d9ee4b2a242c32dd47aa834 [Accessed 2 Feb 2026]."},{"key":"2026050821281529740_j_jpm-2026-0088_ref_002","doi-asserted-by":"crossref","unstructured":"Kurjak, A, Jurkovic, D, Alfirevic, Z, Zalud, I.
