Reliability of the STIR Sequence for Acute Type II Odontoid Fractures

Editor’s Choice August 2014

(3 of 3)

Because STIR images are routinely used for evaluation of the posttraumatic cervical spine, these authors specifically looked at the ability of this sequence to differentiate acute vs. chronic odontoid type II fractures in 75 patients and compared the imaging findings with an equal number of age-matched controls. STIR fared poorly in the detection of fractures in individuals over 57 years of age. Therefore, older patients, particularly those with osteopenia, may have acute odontoid injuries without corresponding STIR hyperintensity.

The STIR sequence is routinely used to assess acute traumatic osseous … Continue reading >>

Effect of Direct Neuroradiologist Participation in Physician Marketing on Imaging Volumes in Outpatient Radiology

Editor’s Choice August 2014

(2 of 3)

This study assessed the benefits of using a sales representative and a neuroradiologistas a marketing and sales team for referrals in outpatient imaging. When referring practices were visited by the 2-person team, referral volumes were 2.5 times greater than when they were visited by the sales representative alone. This impact on imaging referral volumes with the use of the neuroradiologist for direct physician-to-physician marketing supports the concept that neuroradiologist visits are important in establishing and maintaining a relationship with the referring clinician’s office and maximizing imaging referrals.

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.

BACKGROUND AND PURPOSE
Transforaminal corticosteroid injections can be performed in the management of cervical radiculopathy but carry the

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.

BACKGROUND AND PURPOSE
Fusiform vertebrobasilar giant aneurysms are a rare (<1%

Perfusion-Based Selection for Endovascular Reperfusion Therapy in Anterior Circulation Acute Ischemic Stroke

Editor’s Choice July 2014

(2 of 3)

The authors attempted to determine if reperfusion therapy for anterior circulation acute stroke based on MR perfusion resulted in better outcomes at 3 months than that based on noncontrast CT. Perfusion imaging-selected patients had a better outcome than those selected with only noncontrast CT but MR perfusion- and CT perfusion-selected patients had similar outcomes. In this multicenter study, patients with acute stroke who underwent perfusion imaging were more than 2-fold more likely to have good outcomes following endovascular reperfusion therapy

BACKGROUND AND PURPOSE
Controversy exists about the role of perfusion imaging in

Are We Effectively Informing Patients? A Quantitative Analysis of On-Line Patient Education Resources from the American Society of Neuroradiology

Editor’s Choice July 2014

(1 of 3)

The readability of 20 patient education articles found on the ASNR Web site were evaluated using 10 quantitative readability scales and compared with those found on the Web site of the Society of Neurointerventional Surgery. The authors concluded that the patient education resources on both Web sites failed to meet the guidelines of the National Institutes of Health and American Medical Association. Members of the public may fail to fully understand these resources and would benefit from revisions that result in more comprehensible information cast in simpler language.

High Variability in Radiologists’ Reporting Practices for Incidental Thyroid Nodules Detected on CT and MRI

Editor’s Choice June 2014

(3 of 3)

The authors evaluated radiologists’ current reporting practices for incidental thyroid nodules detected on CT and MRI. The most common responses to the survey were to recommend sonography and to report the nodules only in the body of the report. No significant differences were found when years of practice, practice types, and subspecialty were examined. Reporting practices were especially variable for patients with smaller nodules (≤10 mm) and those with multiple nodules and a history of cancer.

BACKGROUND AND PURPOSE
There are no guidelines for reporting incidental thyroid nodules seen on CT and … Continue reading >>

Phlebographic Study Does Not Show Differences Between Patients with MS and Control Subjects

Editor’s Choice June 2014

(2 of 3)

Patients with MS and healthy controls underwent catheter venography to study whether stenoses and/or insufficiency affecting the azygous and internal jugular veins were related to the disease. There were no differences in the presence of stenoses and/or chronic cerebrospinal venous insufficiency between the 2 groups and thus the authors state that their data exclude a direct correlation between these anomalies and MS.

Abstract

BACKGROUND AND PURPOSE
Hypothetical correlation between chronic cerebrospinal venous insufficiency and MS has gained the attention of patients and the scientific community. Studies performed by echo-color Doppler ultrasonography have shown … Continue reading >>

Association of White Matter Hyperintensities with Low Serum 25-Hydroxyvitamin D Levels

Editor’s Choice June 2014

(1 of 3)

The relationship between white matter hyperintensities and serum vitamin D levels was assessed in adults. The authors found a significant relationship between vitamin D and white matter T2 hyperintensities in independent adult outpatients, especially those over 50 years of age, but no relationship between vitamin D levels and brain atrophy.

Abstract

BACKGROUND AND PURPOSE
Vitamin D deficiency is associated with cognitive impairment in the elderly and with increased white matter T2 hyperintensities in elderly debilitated patients. We investigated the relationship between serum vitamin D and brain MR findings in adult outpatients.

Bioactive versus Bare Platinum Coils in the Treatment of Intracranial Aneurysms: The MAPS (Matrix and Platinum Science) Trial

Editor’s Choice May 2014

(3 of 3)

This prospective, randomized, multicenter study compares the efficacy of the Matrix versus bare metal coils. A group of 626 patients were divided between the 2 coil types and aneurysm recurrence and hemorrhage were assessed 1 year after procedures. Recurrences were associated with initial incomplete obliterations and the bare metal coils were not inferior to Matrix coils. Thus, due to cost differences, utilization of Matrix coils may not be justified.

Abstract

BACKGROUND AND PURPOSE
The ability of polymer-modified coils to promote stable aneurysm occlusion after endovascular treatment is not well-documented. Angiographic aneurysm recurrence is … Continue reading >>
