Most reputable medical journals have taken a strong stand against the practice of reporting substantially the same work in two or more different publications. The Editorial Board ofJournal of Medical Ultrasonics wishes to affirm and clarify its position on the subject ofrepetitive publication. When reviewers pointed out duplicate submission, the duplicate paper has been rejected. Apublication will be considered repetitive when materials, method, results, and discussion areessentially the same. Presence or absence of new insights or information, and reference to theearlier publication in the latter publication, will also be taken into consideration. Language of publication will not be accepted as justification for multiple publication. Publication of a paper in the Supplements of the Journal of Medical Ultrasonics will not,however, disqualify it for publication in the Journal of Medical Ultrasonics. When repetitive publication comes to light after publication in the Journal, a Notice of Repetitive Publication will be published and prominently placed in the Journal as soon as possible after discovery.
