This CD provides the viewer with both gross anatomic and MR imaging of the brain in an attractive and friendly interactive format. The anatomic (cryotome sections at 0.15-mm intervals) and the 3T MR images (fluid-attenuated inversion recovery, T1, magnetization-prepared rapid acquisition of gradient echo, and T2 fast spin-echo) takes one through 3 orthogonal planes (axial, coronal, sagittal), providing the chance for structures to be either individually labeled (more than 170 in total) or provide full labeling in every section. For a general overview of cerebral anatomy, this by far supersedes the learning of brain anatomy by the usual type of atlas published in books and journals because of the interactive nature of the material. The fact that the MR images were obtained on a 3T system with a 1056 × 1528 pixel resolution has yielded high-quality detailed images.

The MR images were obtained from a healthy 63-year-old while the anatomic images were obtained from a 72-year-old donor. The use of the CD is intuitive and really requires no instruction on how to use the atlas; nonetheless, a help file explains the options available and how to use each. One simply clicks onto either the gross anatomic specimen or 1 of the 3 MR images, selects the plane in which to visualize the structures, and scrolls through the images. At any point, you click onto the label selector and choose the structure which you wish to identify. After this, you may click the structure label and up pops a definition of the structure, its function, and connections.

In summary, this CD should be required viewing for all residents and fellows in neuroradiology and should be in a department or sectional library. It provides a quick, painless, and instructive review of brain anatomy.

While there are more structures that could have been labeled (for example all the lobules of the vermis or specific brain stem nuclei or numerous white matter tracts), I presume the labeling was kept to a reasonable level so the images would not be unduly cluttered. What is particularly appealing is the way one can follow a given structure through multiple sections; this is particularly appealing for curved structures such as the fornix where one can trace its anterior-to-posterior portions from precommissural to postcommissural to columns to crus and do so in all 3 planes. By simply scrolling an arrow at the bottom of the image, you smoothly follow a structure through multiple sections.
