Instructions for Use of the Atlas

In the "alphabetical index" or the "index by grade" , click on the tumor entity you wish to consult. This will bring up an "initial plate" containing all of the images illustrating the selected tumor entity in "small format" in a didactic order. Clicking on one of these small images will enlarge it to a "midsize format" with a caption . Another click on the image will enlarge it to a "large format" that takes up the entire screen. Download time for the large format is approximately 1 to 2 minutes with a 28800 bps modem, however, meaning that it will thus be used only exceptionally, especially because it is not accompanied by a caption. To return from the "large format" to the "midsize format", merely re-click on the image or click on the "back" button on the tool bar.

After viewing the "midsize image" with its caption, you can advance to the next image or go back to the previous image on the same "initial plate" simply by clicking on the "next image" or "previous image" buttons on the righthand side of the screen. Clicking on the other buttons alllows you to return to the "initial plate" of this tumor entity, to go back to the "previous plate" or to advance to the "next plate" (these plates correspond to other tumor entities), or to consult the "index" or the "table of contents" . The order of presentation of these plates corresponds to the index by grade in order to follow the didactic logic of this atlas. However, any tumor entity can be selected by clicking on the "index" button.

Each initial plate has a "tumor entity number" that starts with a Roman numeral corresponding to the grade (from I to IV). For example, ependymoma is numbered I.09 while anaplastic ependymoma is III.02 and ependymoblastoma is IV.06. Each image number consists of the number of the tumor entity (and thus of the initial plate to which it belongs) followed by a letter and a number. As an example, ependymoma is illustrated by three images numbered I.09.a1 - I.09.b1 - I.09.c1. The letter "a" is attributed to the gross appearance, when appropriate. The major microscopic features are illustrated in images bearing the letter "b" (or "a" if the gross appearance is not shown). Other letters are used to designate subtypes or varieties of tumor entities such as meningiomas, pituitary adenomas, astrocytomas, glioblastomas, medulloblastomas, etc. The number of each image is indicated at the beginning of its caption and is visible transiently when the "small hand" controlled by the mouse rests on the image.
