Differential Diagnosis in Musculoskeletal MRI

differential-dx-mskltl-mri_HollenbergHollenberg GM, Weinberg EP, Meyers SP. Differential Diagnosis in Musculoskeletal MRI. Thieme; 2015; 676 pp; $199.99

Differential Diagnosis in Musculoskeletal MRI was written with the goal of providing a simple reference book on the various pathologies encountered in a musculoskeletal radiology practice through an image-rich presentation of disease states and injuries. In this aim, the authors have succeeded, and should be applauded for the breadth of topics they were able to cover. The book is about 676 pages in length, but because the text is focused and organized into tables and the figures occupy many full pages, the volume reads … Continue reading >>

Fellows’ Journal Club: MRI Grading versus Histology: Predicting Survival of World Health Organization Grade II–IV Astrocytomas

Please check out the accompanying podcast of this blog post (discussion of this article begins at 15:21)



Currently the management of intracranial astrocytic tumors relies heavily on histologic grade.  Although histologic grading is the current gold standard for tumor grading, it is a limited method which can be effected by both sampling error and interobserver agreement.  The heterogeneous nature of astrocytomas makes the identification of necrosis difficult histologically.  MR imaging provides important adjunct information regarding astrocytomas that may not be appreciated histologically and can potentially limit histological undergrading.

The detection of necrosis on MR imaging has significant prognostic … Continue reading >>

Journal Scan – This Month in Other Journals, April 2015

Please check out the accompanying podcast of this blog post (also known as “Annotated Bibliography”):

http://www.ajnr.org/site/Podcasts/April2015AnnotBiblio.mp3 1. Benarroch EE. The amygdala: Functional organization and involvement in neurologic disorders. Neurology. 2015;84(3):313–324.

This detailed review of the functional organization of the amygdala includes intrinsic and extrinsic connections, physiology and its function in humans. Examples of clinical correlations include Kluver-Bucy syndrome, lipoid proteinosis (Urbach-Wiethe disease) and a variety of other neurometabolic diseases. Kluver-Bucy is characterized by visual agnosia, oral exploration of objects, excessive visual attentiveness, and altered sexual behavior. Lipoid proteinosis is an autosomal recessive disorder with a mutations in the ‘extracellular Continue reading >>

3D Atlas of Neurologic Disorders

3d-atlas-nowinskiNowinski WL, Chua BC, Wut Yi SH. 3D Atlas of Neurologic Disorders. Thieme; 2015; $299.99

This Atlas comes on a thumb drive and allows one to easily access key anatomic and associated pathologic disorders on vivid and spectacular rendering of the brain with associated vasculature, nerves, and supporting structures. One is able to see the displays in 3D color displays of tracts, deep structures, and their interconnections. While at first one might consider this an anatomic display, the power of the material is to show in 3D where lesions lie in a host of neurologic diseases. One can scroll … Continue reading >>

Diagnostic Errors in Neurological Emergencies – The Radiologists’ Role

Recently an interesting retrospective study evaluating missed neurological emergencies was published in the journal ‘Diagnosis’.  Physicians from the emergency department of large tertiary care center reviewed cases involving a missed or delayed diagnosis of a neurologic emergency in which a diagnostic error in the ED management was identified. Out of 1168 cases reviewed, 42 were found to have a missed acute neurologic diagnosis, 29 of which were attributed to error. These 29 cases were individually reviewed by the three emergency physician investigators. Of these, approximately 24% were attributed to a radiology resident misread.

The diagnosis most commonly missed was … Continue reading >>

Surgical Management of Pain

Burchiel KJ, Ed. Surgical Management of Pain. 2nd Ed. Thieme; 631 pp; 208 ill; $279.99

Surgical Managment of Pain--Kim J. BurchielThis comprehensive book is aimed primarily at neurosurgeons, but the various clinical pain syndromes that are covered may present to different medical specialists and to primary care providers well before reaching a neurosurgeon. Although the title is Surgical Management of Pain, substantial portions of the book cover pharmacologic and other nonsurgical methods of pain management. Thus, the book may be useful to a range of medical practitioners.

The first section consists of 3 chapters covering the neuroanatomy and physiology of pain mechanisms, including … Continue reading >>

Must-Read AJNR Articles for Neuroradiology Fellows

During the last 8 years AJNR has published 1 to 4 review articles per issue, which are a veritable “who’s who” and “what’s what” in clinical neuroradiology. Additionally, during 2007 to 2010 we also published a series of review articles on physics. From these 2 groups, I have taken a completely subjective approach to select not only my own favorites, but those that I think all neuroradiology fellows should read and that should eventually form part of their learning curriculum.… Continue reading >>
