Method

We have created a brain atlas that is an interactive tool for studying the conventional anatomy of the normal brain based on a magnetic resonance imaging exam of the axial brain. Anatomical structures and particular area are visible as interactive labeled images.

Cross sectional anatomy: MRI of the brain

A mri was performed on a healthy subject, with several acquisition with different weightings: spin-echo T1, T2 and FLAIR, T2 gradient-echo, diffusion, and T1 after gadolinium injection. We obtained 24 axial slices of the normal brain.
Data and DICOM images archived on our PACS (Picture Archiving and Communicating System) were processed and exported as JPEG images. The software Macromedia Flash and Adobe Photoshop allow us the development of an atlas based application with a suitable functionality and user interface for exploration of the neuroanatomy.
Anatomical structures were labeled according to the actual Terminologia Anatomica.

Anatomy of the brain: how to visualize anatomic labels

This module is a comprehensive and affordable learning tool for medical students and residents and especially for neuroradiologists and radiation oncologists.
It provides access to an atlas and to images in the axial planes, allowing the user to learn and review neuroanatomy interactively. Images are labeled, providing an invaluable teaching resource. The test mode allows comprehensive evaluation of user progress.
The horizontal menu gives access to several groups of anatomical structures: encephalic sulci and gyri, limbic system, white matter, ventricle and cisterns architecture, basal nuclei and related structures, optic tract, cerebellum with his lobes according to numbered nomenclature, spinal cord. Vascularisation of the brain can be afforded with the arteries and venous sinuses sections. Pituitary and pineal glands are regrouped as “gland”.
As the cursor is moved over a particular anatomic area, that area is highlighted and labeled: this tool has been chosen to show encephalic lobes: frontal, occipital, parietal, temporal, insula, cerbellum (anterior, posterior and flocculonodular lobes).
The MRI is a particulary powerful exam for studying structures as diencephalon, mesencephalon (mid brain), pons, myelencephalon (medulla oblongata, bulb) and spinal cord.
The vertical left menu provides coronal and sagittal images of the brain, with anatomical schemas based on a three dimensional (3D) model.

awesome, incroyable, fabuloso, April 15, 2008

By ulises bacilio

Hi I'm from México city, I'm a third year radiology resident, i hope i have found you page earlier, so I'm telling everybody about it, it's been very helpful for the new resident.
Merci beaucoup votre site est incroyable, ce la mellieur chose que j'ai vu dans tout ma residence,
excuse moi, mon francais est terrible.

One last question are you from france?.
Gracias por todo.
Saludos desde méxico.
