Digital and print brain atlases have been used with success to help in the planning of neurosurgical interventions. In this paper, a technique presented for the creation of a brain atlas of the basal ganglia and the thalamus derived from serial histological data. Photographs of coronal histological sections were digitized and anatomical structures were manually segmented. A slice-to-slice nonlinear registration technique was used to correct for spatial distortions introduced into the histological data set at the time of acquisition. Since the histological data were acquired without any anatomical reference (e.g., block-face imaging, post-mortem MRI), this registration technique was optimized to use an error metric which calculates a nonlinear transformation minimizing the mean distance between the segmented contours between adjacent pairs of slices in the data set. A voxel-by-voxel intensity correction field was also estimated for each slice to correct for lighting and staining inhomogeneity. The reconstructed three-dimensional (3D) histological volume can be viewed in transverse and sagittal directions in addition to the original coronal. Nonlinear transformations used to correct for spatial distortions of the histological data were applied to the segmented structure contours. These contours were then tessellated to create three-dimensional geometric objects representing the different anatomic regions in register with the histological volumes. This yields two alternate representations (one histological and one geometric) of the atlas. To register the atlas to a standard reference MR volume created from the average of 27 T1-weighted MR volumes, a pseudo-MRI was created by setting the intensity of each anatomical region defined in the geometric atlas to match the intensity of the corresponding region of the reference MR volume. This allowed the estimation of a 3D nonlinear transformation using a correlation based registration scheme to fit the atlas to the reference MRI. The result of this procedure is a contiguous 3D histological volume, a set of 3D objects defining the basal ganglia and thalamus, both of which are registered to a standard MRI data set, for use for neurosurgical planning.

What is an e-book?An e-book is an electronic edition of a printed book that is available as a file. The content does not differ from the printed edition of the book. Thieme offers electronic books in PDF and EPUB formats. For both formats, you need software to display the documents on your reading device. This software is not part of the e-book download.

What is the PDF format?

Adobe PDF format (Portable Document Format) is a standard format in MAC/PC area. Free programs for reading a PDF are available for all common operating systems (e.g. Windows, Mac OS, Linux) and for almost all e-book readers such as e-book readers, tablets or smartphones.

What is the EPUB format?

EPUB (electronic publication) is a standard format for e-books that enables dynamic adaptation of the text to the size of the display device. It is particularly well suited for displaying e-books on tablet PCs, smartphones, and e-book readers.

EPUBs can also be easily displayed on MACs/PCs via the free ADE (Adobe Digital Editions) software, for example.

Can I exchange/return an e-book?

E-books are products that are not suitable for return due to their nature. Just like downloads of other electronic files (movies, music or software), e-books are excluded from the right of withdrawal. A return or exchange is therefore not possible.

This MRI atlas of the spine is the fruit of interdisciplinary cooperation among radiologists, orthopedic surgeons, traumatologists, and neurosurgeons. It is a clinically oriented atlas that covers all important diseases and injuries of the spine. Ample illustrations are supplemented by concise descriptions of anatomy and pathophysiology, the normal and abnormal MRI appearance, diagnostic pitfalls, and the clinical significance of MRI. The clear and didactic style enables readers to revise the fundamentals of spinal anatomy and disease states as a basis for understanding the diagnostic strategies and surgical management. By combining descriptions of the clinical manifestation of spinal disorders with the corresponding MRI findings, the authors hope to help readers develop a meaningful approach to the interpretation of MRI of the spine.
