Efficacy of Skull Plain Films in Follow-up Evaluation of Cerebral Aneurysms Treated with Detachable Coils: Quantitative Assessment of Coil Mass

Fellows’ Journal Club February 2015

(2 of 3)

Coil mass appearances were compared between initial postembolization and follow-up skull radiographs. Changes in the largest diameter of the coil mass generally indicated aneurysm recurrence, especially in the patients with high packing attenuation. Thus, lateral radiographs have the potential to predict aneurysm recurrences.

Do FLAIR Vascular Hyperintensities beyond the DWI Lesion Represent the Ischemic Penumbra?

Editor’s Choice February 2015

(2 of 3)

FLAIR images from over 140 patients with acute MCA infarctions were analyzed and compared with images used to estimate the ischemic penumbra. A FLAIR-DWI mismatch was seen in 72% of patients and the authors concluded that this may be used to identify the ischemic penumbra.

Abstract

BACKGROUND AND PURPOSE
In acute stroke with proximal artery occlusion, FLAIR vascular hyperintensities observed beyond the boundaries of the cortical lesion on DWI (newly defined “FLAIR vascular hyperintensity–DWI mismatch”) may be a marker of tissue at risk of infarction. Our aim was to compare the occurrence

CT Imaging: Practical Physics, Artifacts, and Pitfalls

ct_imag_mamourian_coverMamourian A. CT Imaging: Practical Physics, Artifacts, and Pitfalls. Oxford University Press; 2013; 256 pp; $69.00

There is an immediate appeal to any book which has in its title “practical physics” or “pitfalls”, and such is the case with Dr. Mamourian’s new 256-page softcover book CT Imaging: Practical Physics, Artifacts and Pitfalls.

There are 9 chapters, 5 of which relate directly to neuroradiology (History/Physics, Radiation Safety, Neuro CT Artifacts, Neuro CT Pitfalls, Test Questions). This reviewer went straight to the test questions; after that, it was obvious a review of some aspects of radiation and scanner configuration was needed. … Continue reading >>

Imaging Acute Neurologic Disease: A Symptom-Based Approach

imag_acute_neurol_Filippi_Simon-coverFilippi M, Simon J, eds. Imaging Acute Neurologic Disease: A Symptom-Based Approach. Cambridge, UK: Cambridge University Press; 2014; 391 pp; 196 ill; $150.00

This 382-page multi-authored book, edited by Drs. Massimo Filippi and Jack H. Simon, adeptly and efficiently covers the breadth of acute neurologic disease, with focus not only on imaging but on clinical features as well. Given the variety of manifestations of neurologic illnesses, many of which require urgent or emergent evaluation and intervention, neuroradiologists need to be cognizant of the potential imaging presentations of such a variety of acute processes.

Within this book, there are a … Continue reading >>

Assessment of Intracranial Collaterals on CT Angiography in Anterior Circulation Acute Ischemic Stroke

Fellows’ Journal Club February 2015

(1 of 3)

Different methods of assessing collateral circulation based on CTA were compared in 200 patients with stroke. Only the Miteff scoring system was reliable for predicting favorable outcome in these patients but poor outcomes were predictedby othermethods, too (Maas, Tan, and ASPECTS).
