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.

Abstract

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.

EIC signature

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.

EIC signature

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 >>

Imaging Findings in MR Imaging–Guided Focused Ultrasound Treatment for Patients with Essential Tremor

Editor’s Choice May 2014

(2 of 3)

This study reports the imaging findings after focused ultrasound ablation of the intermedius nuclei in patients with essential tremor. Fifteen patients received follow-up MRI studies on 4 occasions after treatment. Maximal lesion size and perilesional edema predicted a good outcome and all lesions showed consistent and typical findings in the days, weeks, and months after treatment.

Abstract

BACKGROUND AND PURPOSE
MR imaging–guided focused sonography surgery is a new stereotactic technique that uses high-intensity focused sonography to heat and ablate tissue. The goal of this study was to describe MR imaging findings pre- and … Continue reading >>

Safety of Unilateral Endovascular Occlusion of the Cervical Segment of the Vertebral Artery without Antecedent Balloon Test Occlusion

Editor’s Choice May 2014

(1 of 3)

The safety of unilateral vertebral artery occlusion without prior balloon test occlusion was retrospectively assessed in 59 patients who underwent postprocedure CT or MR imaging. No patients had clinical or imaging evidence of postprocedural infarctions. Both dominant and non-dominant vertebral arteries were safely occluded.

EIC signature

Abstract

BACKGROUND AND PURPOSE
Antecedent balloon test occlusion is often performed prior to vertebral artery sacrifice, but there is limited data to suggest this adds a significant clinical benefit, especially in the setting of trauma. Furthermore, balloon test occlusion can be time-consuming, add to the technical complexity of the … Continue reading >>

Spontaneous Lateral Sphenoid Cephaloceles: Anatomic Factors Contributing to Pathogenesis and Proposed Classification

Editor’s Choice April 2014

(3 of 3)

Imaging findings in 26 patients with spontaneous lateral sphenoid cephaloceles were studied. The authors were able to classify these lesions into those involving the lateral recess of the sphenoid sinus that typically manifested as CSF leaks and headaches, and a second type that involved the lateral sphenoidal wing without extension into the sinus and presented with a variety of findings including seizures, headaches, meningitis, or neuropathy, or were incidental. All patients showed sphenoid arachnoid pits and 61% had an empty or partially empty sella.

Spontaneous lateral sphenoid cephaloceles arise from bony defects … Continue reading >>

The Impact of Arterial Collateralization on Outcome after Intra-Arterial Therapy for Acute Ischemic Stroke

Editor’s Choice April 2014

(2 of 3)

The presence of poor leptomeningeal collaterals as assessed by CTA was correlated with patient outcome after receiving intra-arterial treatment for stroke. Functional outcomes in 87 patients with MCA and/or ICA occlusions were retrospectively assessed at 3 months. The authors found that poor arterial collateralization was associated with poor outcome after adjustment for recanalization success. They recommend that future studies include collateral scores as one of the predictors of functional outcome.

EIC signature

Abstract

BACKGROUND AND PURPOSE
Although intra-arterial therapy for acute ischemic stroke is associated with superior recanalization rates, improved clinical outcomes are inconsistently observed

Attitudes about Medical Malpractice: An American Society of Neuroradiology Survey

Editor’s Choice April 2014

(1 of 3)

An email survey yielded over 900 responses from neuroradiologists with regard to their experiences and attitudes about the medicolegal environment. Nearly one-half of neuroradiologists had been sued once, while over 10% had been sued more than 3 times with payouts in the range of US $50,000–$150,000 and up to $1.2 million for lawsuits affecting interventional neuroradiologists. Over 80% of neuroradiologists opined that the system was weighted toward plaintiffs and nearly 20% expressed being extremely concerned about being sued.

Abstract

The concern over medicolegal liability is pervasive among physicians. We sought, through an email … Continue reading >>

Left Hemisphere Diffusivity of the Arcuate Fasciculus: Influences of Autism Spectrum Disorder and Language Impairment

Editor’s Choice March 2014

(3 of 3)

The authors used DTI measurements of the arcuate fasciculus in 14 children with language impairment, in 16 autistic children with language impairment, 18 autistic children without language impairment, and 25 controls. Although white matter abnormalities appeared similar in language impairment and autism spectrum disorder when examining broad white matter measures, detailed analysis indicated different mechanisms for the white matter microstructural anomalies associated with these disorders.

EIC signature

Abstract

BACKGROUND AND PURPOSE
There has been much discussion whether brain abnormalities associated with specific language impairment and autism with language impairment are shared or are disorder specific. … Continue reading >>
