The Development and Challenges of PET/MRI Dual‐Modality Imaging Probes—An Update

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT The integration of Positron emission tomography (PET) with Magnetic resonance imaging (MRI) combines the functional imaging capabilities of PET with the high‐resolution anatomical detail of MRI, creating a synergistic platform for advanced diagnostic imaging and image‐guided therapies. Central to the success of this dual‐modality system is the

Sex‐specific and hormone‐related differences in vascular remodelling in atherosclerosis

European Journal of Clinical Investigation, Volume 53, Issue 1, January 2023., 2023
Abstract Atherosclerosis, a lipid‐driven inflammatory disease, is the main underlying cause of cardiovascular diseases (CVDs) both in men and women. Sex‐related dimorphisms regarding CVDs and atherosclerosis were observed since more than a decade ago.

Pre‐operative transcranial Doppler ultrasound assessment of cerebral collateral circulation in children undergoing veno‐arterial extracorporeal membrane oxygenation or cardiac surgery

Journal of Medical Radiation Sciences, EarlyView.
A pre‐cannulation survey of the circle of Willis (CoW) using transcranial Doppler (TCD) ultrasound was implemented to assess cerebral collateral circulation in children undergoing VA ECMO or cardiac surgery with cervical cannulation. The technique, in use since 2019, employs high‐end ultrasound platforms to assess brain morphology, haemorrhage and ...

Injection Bias Reduction Techniques in Quantitative Angiography Using Patient-Specific Phantoms of Intracranial Aneurysm [PDF]

arXiv
In intracranial aneurysm (IA) treatment, digital subtraction angiography (DSA) monitors device-induced hemodynamic changes. Quantitative angiography (QA) provides more precise assessments but is limited by hand-injection variability. This study evaluates correction methods using in vitro phantoms that mimic diverse aneurysm morphologies and locations ...

Ultrasound Evaluation of the Changes of Ophthalmic Artery Doppler and Optic Nerve Sheath in Pregnant Women With FGR

Journal of Ultrasound in Medicine, EarlyView.
Objectives This study aimed to compare changes in ultrasonic Doppler parameters, particularly the peak ratio (PR) of the ophthalmic artery (OA) and optic nerve sheath diameter (ONSD), in pregnancies complicated by fetal growth restriction (FGR). Furthermore, it sought to evaluate differences in these parameters across various subgroups and analyze the ...

The location of intraparenchymal bleeding determines functional outcome after spontaneous subarachnoid hemorrhage

European Journal of Neurology, Volume 30, Issue 2, Page 372-379, February 2023., 2023
Subarachnoid hemorrhage patients with hemorrhagic lesions of the corpus callosum (n = 6/280) are at an elevated risk of unfavorable 3‐month functional outcome. Abstract Background and purpose Non‐traumatic subarachnoid hemorrhage (SAH) is a devastating disease associated with high morbidity and mortality.

Etiologic and prognostic value of external carotid artery thrombus detection during endovascular therapy for anterior circulation proximal occlusions

European Journal of Neurology, Volume 30, Issue 2, Page 380-388, February 2023., 2023
Abstract Background and purpose An early understanding of stroke mechanism may improve treatment and outcome in patients presenting with large vessel occlusion stroke (LVOS) treated with mechanical thrombectomy (MT). We aimed to investigate whether spontaneous external carotid artery (ECA) embolism detection during MT is associated with stroke etiology

Office‐Based Drainage of a Parapharyngeal Abscess with Surgeon‐Performed Transoral Ultrasound

The Laryngoscope, EarlyView.
This case report presents the use of transoral ultrasound as a novel imaging technique to diagnose and aspirate a parapharyngeal abscess (PPA) under local anesthesia in an outpatient setting. A parapharyngeal abscess (PPA) was diagnosed and aspirated under local anesthesia using transoral ultrasound by an ENT surgeon.
