Irreversible fatal contrast-induced encephalopathy: a case report

open access: yesBMC Neurology, 2019
Background Contrast-induced encephalopathy (CIE) is a well-known complication of iodinated contrast agents during angiography and vascular interventions. It can manifest as hemiparesis, cortical blindness, speech changes, Parkinsonism, confusion, seizure,

Imaging Characteristics of Persistent Carotid‐Vertebrobasilar Anastomoses Detected by Ultrasound

open access: yesJournal of Ultrasound in Medicine, EarlyView.
In this case series, we aimed to evaluate the ultrasonic characteristics of 35 patients with persistent carotid‐vertebrobasilar anastomoses (PCVBA), a rare variant between the anterior and posterior cerebral circulation. Ultrasound detected seven (30.4%, 7/23) primitive trigeminal arteries (PTA), eight (100%, 8/8) primitive hypoglossal arteries (PHA ...

Materials Employed in Preoperative Embolization for Nasopharyngeal Angiofibroma: A Meta‐Analysis

open access: yesThe Laryngoscope, EarlyView.
Studies have shown that pre‐surgical embolization improves outcomes for JNA, but the choice of embolization material remains a topic of debate. This study found PVA is the most used material, and that there may be differences in outcomes and complications between embolization materials.

Simultaneous Photoacoustic and Laser‐Induced Ultrasound Imaging of Animals and Humans via a Semi‐Transparent Ultrasound Transducer

open access: yesLaser &Photonics Reviews, EarlyView.
Combined photoacoustic (PA) and ultrasound (US) imaging commonly requires an external pulser to transmit US waves, making systems relatively complicated and suboptimal. Here simultaneous PA and laser‐induced US imaging is demonstrated without using a US pulser. A semi‐transparent ultrasound transducer converts some portion of excitation laser energy to

Angiografin in cerebral angiography

open access: yesThe British Journal of Radiology, 1971
Abstract Angiografin is a 65 per cent aqueous solution of methylglucamine diatrizoate, containing 305 mg iodine per ml., and it has been available generally since 1968. Experimentally it is less harmful locally and generally than other comparable media.

Advancing Localization Optoacoustic Tomography Using Experimentally‐Derived Effective Point Spread Functions

open access: yesLaser &Photonics Reviews, EarlyView.
This study presents an improved technique for Localization Optoacoustic Tomography using experimentally‐derived effective point spread functions. The method significantly enhances sub‐pixel localization performance, with applicable potential to relatively under‐sampled scenarios and other imaging modalities, paving the way for new frontiers in super ...

Atherosclerosis after pre‐eclampsia: systematic review and meta‐analysis

open access: yesUltrasound in Obstetrics &Gynecology, EarlyView.
ABSTRACT Objective Pre‐eclampsia complicates up to 8% of pregnancies and is associated with increased risk of ischemic cardiac and cerebral disease, which may be prevented through management of cardiovascular risk when early disease stages are detected.

Atypical presentation of pheochromocytoma as acute ischemic stroke and pulmonary embolism, a case report

open access: yesUroPrecision, EarlyView.
Abstract Background Pheochromocytoma is a rare catecholamine‐secreting tumor that often presents with symptoms such as hypertension, palpitations, and sweating due to excessive hormone production. In some cases, the catecholamine‐induced vasoconstriction and hypercoagulability associated with pheochromocytomas can lead to cerebrovascular accidents and ...
