Canine Head Transections (MRI & CT Slide Show)
New! This web app presents a slide show of MRI and CT axial (transverse plane) images through the head of an embalmed, latex-injected, brachycephalic, mongrel canine cadaver. The web app enables students to explore planar head anatomy thoroughly and to compare MRI vs CT views at each transverse level. MRI and CT images are synced during rostral-caudal navigation, which can be manual or automatic (at an adjustable rate). During manual navigation, MRI labels may be displayed (using a button or the spacebar). The keyboard can be used for navigation (arrow keys) and to toggle MRI/CT display (shift key). The auto navigation mode gives students an overview of head planar anatomy. The MRI labels that become available during manual navigation provide detailed identification.
Canine Regional Planar Anatomy Quizzes
This web site enables students to explore canine planar anatomy. MRI, CT and Cadaver-Slab images, displayed in Transverse Plane, Dorsal Plane and Sagittal Plane views, are presented in random order per body region. Two modes of presentation are available: In Quiz Mode, three terms and five target frames are shown per image. Students match terms to frames by dragging or sequentially clicking/tapping. In Atlas Mode, numerous labels per image may be toggled on/off.
Canine MRI Atlas
New. This web site presents MRI images of the canine head, neck, thorax, abdomen (male & female), and pelvis (male & female). Each region can be viewed in transverse, sagittal & dorsal planes; each image has accompanying labels that can be toggled on/off. The mouse or keyboard may be used to navigate through the images and toggle the appearance of labels. At all times, single-key navigation executed by Return/Enter is available: regions [h / n / t / a / p], planes [x / s / d], gender [m / f], and location within an image set [1...9 (10...90%)]. The MRI images are proton-density-weighted from embalmed, latex injected cadavers. (The face region of the head is still under development.)
Canine Head MRI Atlases
This web site presents images of a cadaver Beagle Head (Cranium) obtained by Magnetic Resonance Imaging (T2-weighted images from a 3 Tesla MR system). Three Atlases show MRI images in transverse, sagittal, and dorsal planes of view. Buttons toggle labels and switch between bright and dark versions of the images, a slider generates gradations between bright and dark image versions. (This courseware requires browsers to use a Flash Player plug-in.)
Canine Cadaver Planar Anatomy (cadaver slabs)
New. Canine planar anatomy is presented as 900 x 600 pixel images of cadaver slabs produced by bandsawing frozen cadavers. The head/neck, thorax, and abdomen/pelvis regions are each shown in three planes: sagittal (left to right lateral views), transverse (cranial/rostral to caudal, caudal views), and dorsal (dorsal to ventral, dorsal views). Keyboard arrow keys may be used to navigate among images per plane per region. Use the spacebar or click/tap an image to toggle labels.
Canine Brain MRI Atlas
This web site presents labeled transverse views of a Beagle Brain obtained by Magnetic Resonance Imaging: T2-weighted, T1-weighted, and Proton-Density-weighted MRIs are included. Three viewing options are presented: 1] MRIs are paired with stained tissue sections of a dog brain to facilitate neuroanatomy identification; 2] MRIs are shown within transverse views of the Beagle head; and 3] MRIs are featured in animated quizzes intended to provide knowledge self-assessment of MRI brain structures. (This courseware requires browsers to use a Flash Player plug-in.)
mobile MRI Brain Atlas
This web app presents proton-density-weighted MRI images paired with brain-transection images of a dog brain. The app is intended to provide quick access to canine brain MRI anatomy through a smart phone. Particular brain levels are accessible via a Gallery Menu (tap a small image) or a List Menu (tap a text button). At each level, a button toggles between MRI and brain section images. Labels per image can be switched on/off by tapping the image (or a Show/Hide button). Rostral/caudal buttons are available for navigation to adjacent levels. This web app can be viewed on a smart phone, a tablet, or a computer screen.
Canine Brain Atlas
This Brain Atlas web site consists of twelve transverse levels through a dog brain. The Atlas is accompanied by a Glossary-Index of brain anatomy terms. Labels may be toggled on/off and levels may be navigated with a mouse or key strokes. (Page width is 1200 pixels; a print version of this Atlas is available in A Practical Guide to Canine & Feline Neurology, 2nd ed. by Curtis W. Dewey, Wiley-Blackwell 2008.)

Link: University of Illinois Radiographic Anatomy Imaging
The University of Illinois has produced an outstanding web site for viewing normal radiographic anatomy images. The canine is most thoroughly presented, followed by feline, equine and bovine images. The site is still undergoing development.
