A proof of concept treatment planning study of gated proton radiotherapy for cardiac soft tissue sarcoma

open access: yesPhysics and Imaging in Radiation Oncology, 2021
Background and Purpose: Few studies on radiotherapy of cardiac targets exist, and none using a gating method according to cardiac movement. This study aimed to evaluate the dose-volume advantage of using cardiac-respiratory double gating (CRDG) in terms ...

Molecular Insights Into the Gating Kinetics of the Cardiac hERG Channel, Illuminated by Structure and Molecular Dynamics

open access: yesFrontiers in Pharmacology, 2021
The rapidly activating delayed rectifier K+ current generated by the cardiac hERG potassium channel encoded by KCNH2 is the most important reserve current for cardiac repolarization.

Learning to Denoise Gated Cardiac PET Images Using Convolutional Neural Networks

open access: yesIEEE Access, 2021
Noise and motion artifacts in Positron emission tomography (PET) scans can interfere in diagnosis and result in inaccurate interpretations. PET gating techniques effectively reduce motion blurring, but at the cost of increasing noise, as only a subset of

Trafficking and Gating Cooperation Between Deficient Nav1.5-mutant Channels to Rescue INa

open access: yesFrontiers in Bioscience-Landmark, 2022
Background: Pathogenic variants in SCN5A, the gene encoding the cardiac Na+ channel α-subunit Nav1.5, result in life-threatening arrhythmias, e.g., Brugada syndrome, cardiac conduction defects and long QT syndrome. This variety of phenotypes is underlied

Self‐gated cardiac cine MRI [PDF]

open access: yesMagnetic Resonance in Medicine, 2003
AbstractThe need for ECG gating presents many difficulties in cardiac magnetic resonance imaging (CMRI). Real‐time imaging techniques eliminate the need for ECG gating in cine CMRI, but they cannot offer the spatial and temporal resolution provided by segmented acquisition techniques.

Kinetic model of Nav1.5 channel provides a subtle insight into slow inactivation associated excitability in cardiac cells. [PDF]

open access: yesPLoS ONE, 2013
Voltage-gated sodium channel Nav1.5 has been linked to the cardiac cell excitability and a variety of arrhythmic syndromes including long QT, Brugada, and conduction abnormalities.

Prospective cardiac motion self-gating [PDF]

open access: yesQuantitative Imaging in Medicine and Surgery, 2017
To develop a prospective cardiac motion self-gating method that provides robust and accurate cardiac triggers in real time.The proposed self-gating method consists of an "imaging mode" that acquires the k-space segments and a "self-gating mode" that captures the cardiac motion by repeatedly sampling the k-space centerline.

Gating Approaches in Cardiac PET Imaging [PDF]

open access: yesPET Clinics, 2019
Cardiac PET provides high sensitivity and high negative predictive value in the diagnosis of coronary artery disease and cardiomyopathies. Cardiac, respiratory as well as bulk patient motion have detrimental effects on thoracic PET imaging, in particular on cardiovascular PET imaging where the motion can affect the PET images quantitatively as well as ...
