Transforaminal versus Intra-Articular Facet Corticosteroid Injections for the Treatment of Cervical Radiculopathy: A Randomized, Double-Blind, Controlled Study

Editor’s Choice August 2014

(1 of 3)

In this prospective study, patients with cervical radicular pain were assigned to receive CT-guided transforaminal or facet dexamethasone injections and their outcomes were measured at 4 weeks postprocedure and compared with data collected prior to injections. Patients who had facet injections experienced significant pain reduction scores when compared with those who underwent transforaminal injections. Thus, facet injections are an effective treatment of cervical radiculopathy and represent a valid and safer alternative to transforaminal injections.

clinical-perfusion-mri-coverThis textbook is divided into two sections. The first section covers the basic principles and technical aspects of various methods that are used to measure perfusion with MRI, which would be very valuable to basic scientists working in this field. The second section covers various clinical application of the methods described in section one, which would be of great importance to radiologists.

Section 1

The first chapter describes fundamental aspects of various methods that are used for measuring blood … Continue reading >>

Moyamoya Disease: Diagnosis and Treatment

Wanebo JE, Khan N, Zabramski JM, Spetzler RR, eds. Moyamoya Disease: Diagnosis and Treatment. 1st Ed. Thieme; 2013; 224 pgs; 186 illustrations; $139.99

moyamoya-coverMoyamoya disease (MMD) is a cerebrovascular disease characterized by progressive stenosis of the intracranial internal carotid arteries and their proximal branches. Although rare, MMD can be seen in both children and adults and there is growing evidence that once recognized, this disease needs to be treated aggressively.

Moyamoya Disease: Diagnosis and Treatment is a comprehensive textbook that deals with all the facets of this interesting and unique disease entity, including the classification, pathophysiology, clinical features, diagnosis, and … Continue reading >>

Neuroradiology Signs

Ho M-L, Eisenberg R. Neuroradiology Signs. McGraw-Hill Professional Publishing; 2014; 496 pgs.; $104.95

neuroradiology-signs-coverAside from the whimsical nature of this book, Neuroradiology Signs contains a large series of neuroimages (over 400) that provide a nice review of classic findings of a wide spectrum of cranial and spinal abnormalities. CT, MR, ultrasound, nuclear imaging, and plain radiographs are represented. First, the whimsical part: most images are accompanied by a small color photograph in an attempt to correlate the finding with its “sign.” For example, there is the well-known “snowman” sign of a large pituitary macroadenoma, so of course there is … Continue reading >>

Use of Flow-Diverting Devices in Fusiform Vertebrobasilar Giant Aneurysms: A Report on Periprocedural Course and Long-Term Follow-Up

Editor’s Choice July 2014

(3 of 3)

This article presents the authors’ experience and long-term follow-up of 6 patients with fusiform and giant aneurysms of the vertebrobasilar system treated with flow-diverting devices. Devices were deployed uneventfully with no periprocedural complications. One year later, 3 patients had recurrent cerebral infarctions and 2 had acute thrombotic in-stent occlusions. Four patients died during the follow-up period. The authors do not intend to treat any more patients in this fashion until they have a better understanding of flow-diverting devices in this setting.

Influence of Patient Age on Angioarchitecture of Brain Arteriovenous Malformations

Fellows’ Journal Club July 2014

(3 of 3)

Over 800 AVMs were retrospectively reviewed to determine if clinical and angioarchitectural features varied between children and adults. The authors found that hemorrhages and exclusively deep venous drainage were more common in children but high-risk features such as venous ectasia and feeding artery aneurysm were more common in adults. Thus, these latter high-risk features may take time to develop.

The imaging characteristics and modes of presentation of brain AVMs may vary with patient age. Our aim was to determine whether clinical and angioarchitectural features of brain AVMs differ
