Small intracranial aneurysms of the anterior circulation: A negligible risk?

European Journal of Neurology, Volume 30, Issue 2, Page 389-398, February 2023., 2023
Abstract Background and purpose According to the International Study of Unruptured Intracranial Aneurysms, small (<7 mm) unruptured intracranial aneurysms (IAs) of the anterior circulation (aC) carry a neglectable 5‐year rupture risk. In contrast, some studies report frequencies of >20% of all ruptured IAs being small IAs of the aC.

Physics-informed graph neural networks for flow field estimation in carotid arteries [PDF]

arXiv
Hemodynamic quantities are valuable biomedical risk factors for cardiovascular pathology such as atherosclerosis. Non-invasive, in-vivo measurement of these quantities can only be performed using a select number of modalities that are not widely available, such as 4D flow magnetic resonance imaging (MRI).

Sensory and Autonomic Fibers in Anterior Ethmoid, Posterior Nasal, Posterolateral Nasal Nerves

The Laryngoscope, EarlyView.
All cadaveric anterior ethmoid, posterior, and posterolateral nasal nerves contained roughly equivalent proportions of sensory, parasympathetic, and sympathetic nerve fiber markers. Neurokinin A was the only neuropeptide with consistently greater percent areas across the different nasal nerves.

Inhalable Nano Formulation of Cabazitaxel: A Comparative Study with Intravenous Route

Macromolecular Bioscience, EarlyView.
Nano drug formulation shows no signs of toxicity for IV and INH routes, whereas higher systemic toxicity occurs in free drug formulation in both. Inhalable nano formulation provides higher and longer retention in deep lung regions due to its size and defies rapid systemic absorption in the lungs.

Congenital absence of the internal carotid artery with intercavernous anastomosis

Radiology Case Reports, 2019
Congenitally absent internal carotid artery with intercavernous anastomosis is an exceedingly rare vascular anomaly. We report such a case in a 65-year-old man with chronic symptoms resembling sporadic transient ischemic attacks. While these patients are

Asymmetry analysis of nuclear Overhauser enhancement effect at ‐1.6 ppm in ischemic stroke

Medical Physics, EarlyView.
Abstract Background The nuclear Overhauser enhancement (NOE)‐mediated saturation transfer effect at ‐1.6 ppm, termed NOE(‐1.6 ppm), has demonstrated potential for detecting ischemic stroke. However, the quantification of the NOE(‐1.6 ppm) effect usually relies on a multiple‐pool Lorentzian fit method, which necessitates a time‐consuming acquisition of ...

A historical review of experimental imaging of the beating heart coronary microcirculation in vivo

Journal of Anatomy, Volume 242, Issue 1, Page 3-16, January 2023., 2023
Intravital imaging of the beating heart microcirculation in vivo has been challenging. The past 50 years has seen changes in ways to both stabilise and image the heart with a shift from learning about coronary vascular anatomy and physiology to the role of thromboinflammation and other microcirculatory disturbances in cardiovascular disease.

Simultaneous whole‐brain and cervical spine imaging at 7 T using a neurovascular head and neck coil with 8‐channel transceiver array and 56‐channel receiver array

Magnetic Resonance in Medicine, EarlyView.
Abstract Purpose To develop a 7T neurovascular head and neck (NVHN) coil with an extended longitudinal coverage of the brain and cervical spine, with eight transceiver (TxRx) channels and 56 receive (Rx) channels for dynamic parallel‐transmit (pTx) applications. Methods A dual‐row transceiver array with six elements in the upper row and two elements in

Anatomical variation of the aorta in the West of Scotland – A population with high cardiovascular disease burden. Implications for stent design and deployment

Journal of Anatomy, Volume 242, Issue 1, Page 112-120, January 2023., 2023
A population with a high cardiovascular disease burden was found to have a high degree of anatomical variation in the aortic arch (angulation from coronal plane, origin of the vertebral artery) and the abdominal aorta regions (high degree of taper, high number of collaterals and tortuous vessels).
