To explore the safety and opportunity of the "waffle-cone" technique for the treatment of intracranial aneurysm. ⋯ The "waffle-cone" technique is a safe, simple and alternative for the complex, wide-necked bifurcation aneurysms with acute angles between the parent artery and distal vessels. Long-term following-up results are needed to evaluate the efficacy of this technique.

Case Reports
Early experience with low contrast imaging (LCI) technology during neuroendovascular interventional procedures.
Early recognition of complications during intracranial neuroendovascular interventions is important for medical decision making and prompts administration of life-saving treatments. Low contrast imaging (LCI) provides computed tomographic (CT)-like images of anatomical brain structures, capable of detecting hydrocephalus and intracranial hemorrhage complications. We present our early experience with LCI using the Toshiba Infinix-i biplane angiographic suite during neurointerventional cases, including acute stroke interventions, aneurysm embolization, and subarachnoid hemorrhage management. ⋯ LCI is a promising tool in the arsenal of a neuroendovascular interventionist, especially when a complication is suspected during an intervention, potentially obviating the need for immediate transfer of the patient to a conventional CT scanner. Further studies comparing LCI with conventional noncontrast CT imaging are necessary.

Clinical Trial
Increased common carotid artery wall thickness is associated with rapid progression of asymptomatic carotid stenosis.
This study aimed to identify clinical and ultrasound imaging predictors of progression of carotid luminal narrowing in subjects with asymptomatic moderate internal carotid artery (ICA) stenosis. ⋯ Our results confirm the role of carotid wall thickening as a marker of atherosclerosis. Carotid IMT measurement should be considered to implement risk stratification in patients with asymptomatic carotid disease.

Characterizing the morphologies of occluded artery segments may help elucidate the etiology of chronic intracranial artery occlusion. We acquired high-resolution MRI (HR-MRI) of the middle cerebral artery (MCA) in patients with chronic unilateral MCA occlusion and evaluated the MRI and clinical findings. ⋯ HR-MRI can characterize the morphology of pathologic segments of chronic unilateral MCA occlusions in vivo. In chronic MCA occlusion, morphological analysis using HR-MRI may enhance the effort to assess the etiology in company with the angiographic finding.

To determine if a voxel-wise "co-analysis" of structural and diffusion tensor magnetic resonance imaging (MRI) together reveals additional brain regions affected in mild cognitive impairment (MCI) and Alzheimer's disease (AD) than voxel-wise analysis of the individual MRI modalities alone. ⋯ These results suggest that in corpus callosum and temporal regions macro- and microstructural variations in MCI can be congruent, providing potentially new insight into the mechanisms of brain tissue degeneration.
