Neuroimaging Features and Predictors of Outcome in Eclamptic Encephalopathy: A Prospective Observational Study

Fellows’ Journal Club September 2014

(2 of 3)

Imaging findings in 45 patients with eclampticposterior reversible encephalopathy syndrome were assessed. The most common affected areas were the occipital, parietal, frontal, and temporal lobes. Serum creatinine, uric acid, and lactate dehydrogenase values and presence of moderate or severe PRES were significantly associated with mortality. Eclamptic PRES demonstrated a higher incidence of atypical distributions and cytotoxic edema than previously thought.

EIC signature

Abstract

BACKGROUND AND PURPOSE
Posterior reversible encephalopathy syndrome is associated with eclampsia. We assessed the distribution and nature of typical and atypical cranial MR imaging findings in these patients and their correlation

Brain Structure and Function in Patients after Metal-on-Metal Hip Resurfacing

Editor’s Choice September 2014

(2 of 3)

Malfunction of metal-on-metal hip prostheses may produce visual, hearing, and motor deficits. These authors compared brain volumes, metal deposition, and gray matter attenuation in 2 groups of patients 8 years after surgery. Whole blood cobalt and chromium levels were higher in patients with metal-on-metal prostheses and associated with subtle structural changes in the visual pathways and basal ganglia.

EIC signature

Abstract

BACKGROUND AND PURPOSE
Hip prostheses that use a metal-on-metal articulation expose the brain to elevated metal concentrations that, in acute excess due to prosthesis malfunction, is associated with neurologic damage, including visual and hearing

Early Basal Ganglia Hyperperfusion on CT Perfusion in Acute Ischemic Stroke: A Marker of Irreversible Damage?

Fellows’ Journal Club September 2014

(1 of 3)

These authors found that increased cerebral blood flow and volume were seen in the basal ganglia of 4.3% of patients with ischemic strokes with CT perfusion. All patients had underlying MCA occlusions, 30% underwent hemorrhagic transformations, and the hyperperfused areas eventually became infarcted in all. Thus, acute basal ganglia hyperperfusion in patients with stroke may indicate nonviable parenchyma.

EIC signature

Abstract

BACKGROUND AND PURPOSE
CT perfusion scans are often used in acute stroke evaluations. We aimed to assess the outcome of areas of basal ganglia hyperperfusion on CTP in patients with acute ischemic stroke.… Continue reading >>

Cost-Effectiveness of CT Angiography and Perfusion Imaging for Delayed Cerebral Ischemia and Vasospasm in Aneurysmal Subarachnoid Hemorrhage

Editor’s Choice September 2014

(1 of 3)

This comparative-effectiveness and cost-effectiveness study assessed the use of CT angiography and perfusion in patients with cerebral ischemia after aneurysmal SAH. The authors found that CTA and CTP should be the preferred imaging strategy in SAH, compared with transcranial Doppler ultrasound, leading to improved clinical outcomes and lower health care costs.

EIC signature

Abstract

BACKGROUND AND PURPOSE
Delayed cerebral ischemia and vasospasm are significant complications following SAH leading to cerebral infarction, functional disability, and death. In recent years, CTA and CTP have been used to increase the detection of delayed cerebral ischemia and vasospasm. Our … Continue reading >>

Hyperintense Basilar Artery on FLAIR MR Imaging: Diagnostic Accuracy and Clinical Impact in Patients with Acute Brain Stem Stroke

Fellows’ Journal Club August 2014

(3 of 3)

Because FLAIR high signal intensity in occluded arteries occurs elsewhere in the brain, these authors analyzed the signal of the basilar artery in 20 instances of occlusion in a group of patients who also underwent DSA. While the FLAIR hyperintense basilar artery sign showed moderate sensitivity, its specificity and accuracy were high for the detection of occlusions. The extent of the occlusion also predicted survival.

EIC signature

Abstract

BACKGROUND AND PURPOSE
FLAIR-hyperintense vessels are known to be a sign of sluggish collateral blood flow in hemispheric vessel occlusion. Additionally, they seem to have a … Continue reading >>

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.

Abstract

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