Special Reports |
1 From the Radiological Society of North America, 820 Jorie Blvd, Oak Brook, IL 60523. Address correspondence to John J. Humpal, Managing Editor, Radiology (e-mail: humpal@rsna.org).
Index terms: Radiology (journal)
Illustrations include radiologic images, graphs, anatomic drawings, diagrams of techniques, photographs of devices, flow charts, and photomicrographs. These various types of illustrations are helpful to visually report or clarify the results of a study, to explain methods, or to show a device or technique being discussed.
Because of the expense involved in reproducing a color image, the Editor of Radiology discourages the use of color unless it is necessary to convey the message of the image. For all illustrations, it is essential that the original image be of highest quality, as some degradation may occur in the reduction and reproduction process. To avoid reducing the image by more than 50% or enlarging by more than 10%, which would distort detail, unretouched glossy prints no larger than 12.7 x 17.8 cm (5 x 7 inches) are desirable. The image printed in the Journal typically will be smaller than the original; therefore, the submitted illustration should show only the area(s) of interest with enough surrounding area for orientation purposes. Also, the keys (arrows, letters, symbols) should be large enough on the original to be distinguishable after reduction. Computer-generated artwork should be done in continuous tones (ie, solid black, solid gray, solid white), as opposed to dotted shadings or several shades of gray. Some adjustment to lighten or darken the image can be made, but if the original lacks the desired contrast, only very minimal improvement will occur. Also, in the final print stage the reproduced image may darken by up to 10%.
Digital images submitted on 3
-inch disk, ZIP disk, or CD are acceptable if they meet the following specifications. All scanned photographic images should be submitted as 300-dpi TIFs, and all scanned line-art images should be submitted as 800–1,200-dpi TIFs. Image mode should be CYMK for color photographic images, gray scale for black-and-white photographic images, and bit map for line-art images.
Images labeled in Photoshop software (Adobe) should be provided as PSDs without the layers merged or the image flattened.
The size of the submitted digital image should be as close as possible to the print size: 2
inches wide for one journal column, 3 inches wide for one and a half columns, and 4 inches wide for 2 columns.
Each image file should be named, and the following should be provided with the disk: a hard-copy inventory of the disk, description of file source, three sets of proofs obtained with at least an 800-dpi-resolution printer.
Throughout the production process, great care is taken in cropping and sizing the original illustration and in reviewing the quality of the photoproof (revising as necessary) to obtain the best possible image in the final print version of the Journal.
Each illustration includes a caption that is explicit enough to stand alone so the reader does not have to refer to the text. Each caption for a radiologic image includes pertinent information, such as the type of image, its plane, whether or not contrast material was used, pulse sequence parameters for magnetic resonance images, and the features to be observed by the reader. All features described in the caption are labeled with professional-quality arrows or other keys, with a different label used for each feature. Within the text, illustrations are cited in consecutive order with arabic numerals, with the parts generally designated with lowercase letters. Text around the citation should agree with but not duplicate the caption to that illustration.
RSNA journals discourage the use of previously published illustrations unless absolutely essential, because the publisher may require the author to pay a fee and some publishers will not grant permission for electronic publication. The latter precludes these illustrations from the online versions of the journals. If used, it is essential to obtain written permission from the copyright holder, and a statement that the image is reprinted with permission must be included in the caption.
The online versions of the journals provide an interesting opportunity to display cine images. Movie files should be in the widely implemented standard formats MPEG (.mpg, .mpeg) and QuickTime (.qt, .mov). Audio should be in the standard .au or Real Audio (.ra, .ram) format. Other material that may be considered for online-only publication as a supplement to an article in the print journal includes relevant images whose number would exceed the limits of print publication; relevant data in the form of tables, text, or equations; and Java applets and other programs that allow expansion of browser capabilities to support interactivity in areas such as image display and computer-assisted instruction.
The Publication Information for Authors pages appearing in each issue of the journal give complete details on submitting illustrations for the print journal. Also, these instructions and complete instructions regarding submission of supplementary material are available online at the RSNA Web site (www.rsna.org) under "Publications."
