SWI IMPROVES DISCRIMINATION BETWEEN SOLITARY ENHANCING BRAIN LESIONS
H.S. Kim, G.-H. Jahng, C.W. Ryu, and S.Y. Kim. Added Value and Diagnostic Performance of Intratumoral Susceptibility Signals in the Differential Diagnosis of Solitary Enhancing Brain Lesions: Preliminary Study. AJNR Am J Neuroradiol first published on May 20, 2009 as doi: 10.3174/ajnr.A1635
This is a great article that shows how susceptibility-weighted imaging (SWI) can improve the diagnostic performance of MRI in distinguishing GBM from other solitary enhancing lesions such as metastasis and lymphoma. High grade gliomas have more intratumoral susceptibility hypointense signals than other types of lesions, probably due to large amounts of deoxyhemoglobin related to increased blood supply, … Continue reading >>
Problem Solving in Musculoskeletal Imaging
W. Morrison and T. Sanders, eds. Mosby; 2008, 788 pages, $149.00.
Conventional musculoskeletal radiology textbooks have traditionally been organized according to either disease category or body part, focusing on the imaging appearance of the entities presented. The end result has, at times, been exhaustive, yielding texts that are easily referenced but hard to read.
The “Problem Solving” series addresses this issue from a different perspective. Authors are asked to describe their approach to common imaging dilemmas in a textbook that is intended to be read cover-to-cover and not only as a reference source. The ultimate goal is for readers to … Continue reading >>
Brain Hypoxia and Ischemia
G.G. Haddad and S.P. Yu, eds. Totowa, NJ: Humana Press; 2009, 343 pages, 47 illustrations, $159.00.
The stated intent of this multi-authored volume is to provide a broad mechanistic foundation for understanding brain disorders attributable to oxygen dysregulation. The editors are highly accomplished investigators. Gabriel G. Haddad, MD, is a renowned specialist in pediatric respiratory medicine and is presently chair of pediatrics at the University of California San Diego and Rady Children’s Hospital. His published contributions are in normal and disordered respiratory physiology, hypoxia-mediated cell death and its signaling pathways, the effects of hypoxia on developing organ systems, and physiologic … Continue reading >>
Atlas of Clinical Neurology, 3rd ed.
Roger N. Rosenberg, ed. Springer; 2009, 560 pages, 223 illustrations, $199.00.
For those who prefer a highly visual display and description of clinical neurology, this 560-page atlas would, at first glance, seem to be inviting; however, for those who would like to see an atlas with strong linkages between imaging and neurology, this text will be disappointing. Of course, it is fair to remember that this atlas was not designed with the neuroradiologist in mind; nonetheless, it is surprising that very little care was given to the selection of images, to the editing of images and legends, and to a … Continue reading >>
Musculoskeletal MRI, 2nd ed.
C. Helms, N. Major, M. Anderson, P.E. Kaplan, and R. Dussault, eds. Saunders; 2009, 456 pages, 630 illustrations; $129.00.
Although aimed primarily at residents, fellows, and those involved with musculoskeletal (MSK) radiology, this second edition of Musculoskeletal MRI, written by Clyde Helms, Nancy Major, Mark Anderson, Phoebe Kaplan, and Robert Dussault has portions that would be of interest to neuroradiologists.
This reviewer’s very first impression was here is a text that, unlike many subspecialty texts these days, can actually be lifted off the desk and held comfortably without risking a pulled muscle. It is compact and well illustrated and … Continue reading >>
Neuroimaging Clinics of North America: Multiple Sclerosis, Part I: Background and Conventional MRI, Vol. 18, No. 4 and Part II: Nonconventional MRI Techniques, Vol. 19, No. 1
M. Filippi, guest ed. Philadelphia: W.B. Saunders; 2008, Part I: pages 563–719, 66 figures; Part II: pages 1–132, 46 figures.
The introduction of MR imaging to the evaluation of patients with multiple sclerosis (MS) has dramatically altered our understanding of the disease in recent decades, making it abundantly clear to researchers and clinicians that the pathogenesis of MS is much more complex than the simple plaque-centric theory, which previously dominated our thinking. Because of their improved sensitivity for detecting abnormalities in the brain and spinal cord over clinical assessment alone, conventional MR imaging techniques have become indispensable tools for initial … Continue reading >>
Surgery of Spinal Tumors
J. Klekamp and M. Samii, eds. Springer; 2007, 526 pages, 1862 illustrations, $389.00.
Neuroradiologists infrequently observe the intraoperative findings of patients whose imaging studies they have interpreted unless they are actively involved with intraoperative spinal sonography (which comprises a vanishing small number of radiologists). Now with this textbook, Surgery of Spinal Tumors, rich in color photographs from the operating room (OR), a glance into surgical correlations is possible. This, of course, is not a substitute for being in the OR and watching step-by-step tumor removal, but the book is, nonetheless, instructional.
The authors, both German neurosurgeons, have compiled their … Continue reading >>
Principles and Advanced Methods in Medical Imaging and Image Analysis
A.P. Dhawan, H.K. Huang, D.-S. Kim, eds. World Scientific Publishing; 2008, 868 pages, $228.00.
At first glance at the cover and size of Principles and Advanced Methods in Medical Imaging and Image Analysis,a passerby might think that it is the latest Harry Potter novel; however, the gadgets and technology described in its text are far more complex than those seen in Hogwarts School of Witchcraft and Wizardry. The authors undertook the very difficult task of describing the principles of imaging such that the imaging novice could quickly move from the purpose of a particular technique to the mathematics, physics, … Continue reading >>
Current Diagnosis and Treatment in Neurology
J.C.M. Brust, ed. McGraw-Hill; 2006, 750 pages, $62.95.
This softcover book, Current Diagnosis and Treatment in Neurology, 750 pages, fills a need that trainees in neurology may have for a quick and concise description of central nervous system and peripheral nervous system diseases. Each disease and/or each symptom starts with a simple chart entitled “Essentials of Diagnosis.” The book begins with a short description of the major neurologic investigations (electroencephalography, electromyography, and neuroradiology) and follows with 33 separate chapters, each dealing with a separate disease state. Clearly the 13-page chapter on neuroradiology is not intended for radiologists because it … Continue reading >>
Brain Imaging: Case Review Series
L.A. Loevner. Mosby Elsevier; 2008, 288 pages, $49.95.
Case-based review books are increasingly popular, explained by the recognized need to continually quiz oneself for Board Certification/Certificate of Added Qualifications/ Maintenance of Certification and because these books tend to be more fun than plowing through a textbook. To be effective, such a book must be challenging to all degrees of expertise—from resident to fellow to practicing neuroradiologist/attending level. Brain Imaging: Case Review Series written entirely by Laurie Loevner is constructed like others in this series in the past—straightforward cases (“Opening Round”) first, followed by increasingly challenging cases under “Fair Game and … Continue reading >>
