ASL-DWA: An Improved A-Star Algorithm for Indoor Cleaning Robots

IEEE Access, 2022
The traditional A-star algorithm has many search nodes, and the obtained path has polylines and cannot avoid local unknown obstacles. In response to these problems, this paper proposes a new improved A-star algorithm suitable for indoor cleaning robots ...

Multidelay ASL of the pediatric brain

British Journal of Radiology, 2022
Arterial spin labeling (ASL) is a powerful noncontrast MRI technique for evaluation of cerebral blood flow (CBF). A key parameter in single-delay ASL is the choice of postlabel delay (PLD), which refers to the timing between the labeling of arterial free

Optimizing MRF‐ASL scan design for precise quantification of brain hemodynamics using neural network regression [PDF]

Magnetic Resonance in Medicine, 2019
Arterial Spin Labeling (ASL) is a quantitative, non‐invasive alternative for perfusion imaging that does not use contrast agents. The magnetic resonance fingerprinting (MRF) framework can be adapted to ASL to estimate multiple physiological parameters ...

Robust Multi-TE ASL-Based Blood–Brain Barrier Integrity Measurements

Frontiers in Neuroscience, 2021
Multiple echo-time arterial spin labelling (multi-TE ASL) offers estimation of blood–tissue exchange dynamics by probing the T2 relaxation of the labelled spins. In this study, we provide a recipe for robust assessment of exchange time (Texch) as a proxy

Multiband multi-echo simultaneous ASL/BOLD for task-induced functional MRI

PLoS ONE, 2018
Typical simultaneous blood oxygenation-level dependent (BOLD) and arterial spin labeling (ASL) sequences acquire two echoes, one perfusion-sensitive and one BOLD-sensitive. However, for ASL, spatial resolution and brain coverage are limited due to the T1

ASS1 and ASL suppress growth in clear cell renal cell carcinoma via altered nitrogen metabolism

Cancer & Metabolism, 2021
Background Kidney cancer is a common adult malignancy in the USA. Clear cell renal cell carcinoma (ccRCC), the predominant subtype of kidney cancer, is characterized by widespread metabolic changes.

Cerebrovascular reactivity measurements using simultaneous 15O-water PET and ASL MRI: Impacts of arterial transit time, labeling efficiency, and hematocrit

NeuroImage, 2021
Cerebrovascular reactivity (CVR) reflects the capacity of the brain to meet changing physiological demands and can predict the risk of cerebrovascular diseases.

A nationwide assessment of hepatocellular adenoma resection: Indications and pathological discordance

Hepatology Communications, EarlyView., 2022
Abstract Hepatocellular adenomas (HCAs) are benign liver tumors associated with bleeding or malignant transformation. Data on the indication for surgery are scarce. We analyzed indications and outcome of patients operated for HCAs < 50 mm compared to HCAs ≥ 50 mm. Changes in final postoperative diagnosis were assessed.

Using Etymology to Link ASL to LSF

Deaf Studies Digital Journal, 2021
: The science of etymology involves studying changes in the form and analysis of words. Research on the etymology of specific signs in ASL can also provide us with the tools to link the history of ASL to early French Sign Language (LSF), to which it is ...
