For decades, the determination of bone maturity has relied on a visual evaluation of skeletal development in the hand and wrist, most commonly using the Greulich and Pyle atlas. The Gilsanz and Ratib ...digital atlas takes advantage of the advent of digital imaging and provides a more effective and objective approach to skeletal maturity assessment. This atlas integrates the key morphological features of ossification in the bones of the hand and wrist and provides idealized, sex- and age-specific images of skeletal development. This computer-generated set of images should serve as a reasonable alternative to the reference books currently available.
During the second trimester, the human fetal brain undergoes numerous changes that lead to substantial variation in the neonatal in terms of its morphology and tissue types. As fetal MRI is more and ...more widely used for studying the human brain development during this period, a spatiotemporal atlas becomes necessary for characterizing the dynamic structural changes. In this study, 34 postmortem human fetal brains with gestational ages ranging from 15 to 22 weeks were scanned using 7.0 T MR. We used automated morphometrics, tensor-based morphometry and surface modeling techniques to analyze the data. Spatiotemporal atlases of each week and the overall atlas covering the whole period with high resolution and contrast were created. These atlases were used for the analysis of age-specific shape changes during this period, including development of the cerebral wall, lateral ventricles, Sylvian fissure, and growth direction based on local surface measurements. Our findings indicate that growth of the subplate zone is especially striking and is the main cause for the lamination pattern changes. Changes in the cortex around Sylvian fissure demonstrate that cortical growth may be one of the mechanisms for gyration. Surface deformation mapping, revealed by local shape analysis, indicates that there is global anterioraposterior growth pattern, with frontal and temporal lobes developing relatively quickly during this period. Our results are valuable for understanding the normal brain development trajectories and anatomical characteristics. These week-by-week fetal brain atlases can be used as reference in in vivo studies, and may facilitate the quantification of fetal brain development across space and time.
Resting state functional connectivity MRI (rsfc-MRI) reveals a wealth of information about the functional organization of the brain, but poses unique challenges for quantitative image analysis, ...mostly related to the large number of voxels with low signal-to-noise ratios. In this study, we tested the idea of using a prior spatial parcellation of the entire brain into various structural units, to perform an analysis on a structure-by-structure, rather than voxel-by-voxel, basis. This analysis, based upon atlas parcels, potentially offers enhanced SNR and reproducibility, and can be used as a common anatomical framework for cross-modality and cross-subject quantitative analysis. We used Large Deformation Diffeomorphic Metric Mapping (LDDMM) and a deformable brain atlas to parcel each brain into 185 regions. To investigate the precision of the cross-subject analysis, we computed inter-parcel correlations in 20 participants, each of whom was scanned twice, as well as the consistency of the connectivity patterns inter- and intra-subject, and the intersession reproducibility. We report significant inter-parcel correlations consistent with previous findings, and high testaretest reliability, an important consideration when the goal is to compare clinical populations. As an example of the cross-modality analysis, correlation with anatomical connectivity is also examined.
For students and clinical professionals who are learning anatomy, participating in a dissection lab, sharing anatomy knowledge with patients, or refreshing their anatomy knowledge, the Netter Atlas ...of Human Anatomy illustrates the body, region by region, in clear, brilliant detail from a clinician's perspective. Unique among anatomy atlases, it contains illustrations that emphasize anatomic relationships that are most important to the clinician in training and practice. Illustrated by clinicians, for clinicians, it contains more than 550 exquisite plates plus dozens of carefully selected radiologic images for common views. Presents world-renowned, superbly clear views of the human body from a clinical perspective, with paintings by Dr. Frank Netter as well as Dr. Carlos A. G. Machado, one of today's foremost medical illustrators. Content guided by expert anatomists and educators: R. Shane Tubbs, Paul E. Neumann, Jennifer K. Brueckner-Collins, Martha Johnson Gdowski, Virginia T. Lyons, Peter J. Ward, Todd M. Hoagland, Brion Benninger, and an international Advisory Board. Offers region-by-region coverage, including muscle table appendices at the end of each section and quick reference notes on structures with high clinical significance in common clinical scenarios. Contains new illustrations by Dr. Machado including clinically important areas such as the pelvic cavity, temporal and infratemporal fossae, nasal turbinates, and more. Features new nerve tables devoted to the cranial nerves and the nerves of the cervical, brachial, and lumbosacral plexuses. Uses updated terminology based on the second edition of the international anatomic standard, Terminologia Anatomica, and includes common clinically used eponyms. Provides access to extensive digital content: every plate in the Atlas?and over 100 bonus plates including illustrations from previous editions?is enhanced with an interactive label quiz option and supplemented with "Plate Pearls" that provide quick key points and supplemental tools for learning, reviewing, and assessing your knowledge of the major themes of each plate. Tools include over 300 multiple choice questions, videos, 3D models, and links to related plates. Own your own personal copy of the world-famous Netter Atlas of Human Anatomy! This well-loved title, now in 8th edition, is available in multiple options. Choose the one best for you: Netter Atlas of Human Anatomy: Classic Regional Approach-described above Netter Atlas of Human Anatomy: A Systems Approach-Same content as the classic regional approach, but organized by organ systems. Netter Atlas of Human Anatomy: Classic Regional Approach with Latin terminology All options contain the same table information and same 550+ illustrated plates painted by clinician artists, Frank H. Netter, MD, and Carlos Machado, MD.
