Aunt Mickey (They Look the Same until You Undress Them). Meningioma or Something Else?
51 year old lady presented with headache and gait disturbances. An MRI including perfusion imaging was obtained. MRI revealed an extra-axial, dural based mass of the posterior fossa which was isointense to gray matter on T1 weighted sequence and hyperintense to gray matter on T2 weighted sequence. There was no diffusion restriction. On T2 weighted sequence, there was wedge shaped area of perilesional T2 hyperintensity extending transversely and superiorly to involve vermis. With contrast, the lesion showed intense homogenous enhancement. On perfusion study, there was considerable increase in rCBV. Preoperatively it was diagnosed as meningioma and the patient was scheduled … Continue reading >>

Identification of Infarct Core and Penumbra in Acute Stroke Using CT Perfusion Source Images • X.-C. Wang, P.-Y. Gao, J. Xue, G.-R. Liu, and L. Ma
Although the core of an infarct is clearly seen on diffusion-weighted imaging and corresponds to the hypodensity seen on initial CT images, it is not clear if source images from CT perfusion can consistently identify it. In this study, the authors imaged 42 patients with CTP (CBV and CBF) and used the source images and perfusion studies to try to identify the core and penumbra, then compared their results with those based … Continue reading >>

Association of White Matter Hyperintensity Measurements on Brain MR Imaging with Cognitive Status, Medial Temporal Atrophy, and Cardiovascular Risk Factors • J. Appel, E. Potter, N. Bhatia, Q. Shen, W. Zhao, M.T. Greig, A. Raj, W.W. Barker, H. Potter, E. Schofield, Y. Wu, D.A. Loewenstein, and R. Duara
Features of cardiovascular-related brain changes may overlap somewhat with those of Alzheimer patients. In this prospective study, the authors evaluated the presence and severity of white matter hyperintensities and mesial temporal atrophy in 192 patients with no cognitive impairment, mild cognitive impairment, and probable Alzheimer disease. Cardiovascular risk factors were … Continue reading >>
AJNR: Changes for 2010
AJNR is constantly changing, many times thanks to suggestions made by our readers and others by decisions taken by myself and the senior editors. These are some of the changes that will happen this year:
Physics review articles: These have been very difficult to obtain despite due diligence of our two physics consultants. More importantly, they have not performed well and have been read, downloaded and quoted a surprisingly small number of times. For the time being we will discontinue them on regular basis and we are in the process of rethinking what would be best way to bring some … Continue reading >>

MRI Normal Variants and Pitfalls
MRI: Normal Variants and Pitfalls. Laura W. Bancroft, Melena D. Bridges (authors). Wolters Kluwer|Lippincot Williams & Wilkins 2008, 850 pages, 1828 illustrations, $185.00.
Often a confounding issue in image interpretation is distinguishing a normal variant from a pathologic condition, and in MR imaging, this problem can be particularly vexing. In an attempt to clarify some of these problems, Drs. Bancroft and Bridges have published a textbook MRI: Normal Variants and Pitfalls; unfortunately, the neuroradiology portions of this book fail to clarify many of the issues involved in neuro MR imaging. In the Head chapter in particular, the material … Continue reading >>

Although not written with neuroradiologist in mind, Neurosurgery Case Review by Drs. Nader and Sabbagh presents material in a case by case format, challenging the reader to answer questions is (usually 6 to 12 per case) relative to image interpretation, diagnosis, and patient management. The answer to each is highlighted in a bullet type narrative. The material is divided into three sections, (1) Intracranial Pathology, (2) Spinal and Peripheral Nerve Pathology, and (3) Neurology. A total of 113 cases are … Continue reading >>
3D Head & Neck Anatomy with special Senses and Basic Neuroanatomy
3D Head & Neck Anatomy with special Senses and Basic Neuroanatomy. Barry Berkovitz, Claudia Kirsch, Bernard J. Moxham, Gus Alusi, Tony Cheesman (Authors). Primal Pictures 2009, DVD, $345.00.
This is an interactive DVD which displays head and neck anatomy in a pictorial fashion in combination with multiplanar T1 weighted MR images. The setup allows one to scroll over the MR images or over the anatomic drawings and with that the major structures are indentified. Additionally, movements of various structures are played in a cine-like mode and include eye, cervical spine, TMJ, larynx, face, and muscle animation. The drawings are … Continue reading >>
