THE SILVER ANNIVERSARY OF THE AMERICAN JOURNAL OF NEURORADIOLOGY: Twenty-Five Years of Documenting Advances in Neuroradiology This issue of the American Journal of Neuroradiology

marks our 25th anniversary. The silver border on the journal’s cover and Reed Murtagh’s clever cartoon help celebrate this important milestone in our history. The AJNR has evolved from what many newly trained radiologists would now consider a “primordial neuroradiological ooze ” in 1980 to the publication of the most recent advances in neuroimaging and neu-rointervention. These scientific advances have been mirrored by simultaneous improvements in the for-matting and publication of the journal; the ownership of the journal by the ASNR in 1986, self-publication in 1992, and on-line publication in 2000 are just three of the more notable events of the past 25 years. The cover illustrates the steps in “evolution ” to a more advanced form of existence, a process that has been guided by the editors of the journal and supported by the Executive Committee of the ASNR. While it seems obvious today that American neu-roradiology should have a journal published under the sponsorship of the ASNR, that opinion was not uniformly shared 26 years ago. There were some who, for a number of reasons, felt that neuroradiology ought to remain under the umbrella of the larger diagnostic radiology journals. Time and experience has shown that the vision of those who advocated a separate specialty journal was correct. Large societies such as the ASNR flourish when they have their own dedicated vehicle for publishing scientific material, a concept which is further strengthened when associ-ated societies contribute their efforts and material to a single widely read journal. This in particular per-tains to those societies that call the AJNR their hom
