Low dose SPECT image denoising using a generative adversarial network [PDF]

arXiv, 2019
The image noise level and resolution of SPECT images are relatively poor attributed to the limited number of detected counts and various physical degradation factors during acquisitions. This study aims to apply and evaluate the use of generative adversarial network (GAN) method in static SPECT image denoising. A population of 4D extended cardiac-torso

SPECT in Focal Epilepsies [PDF]

Behavioural Neurology, 2000
Brain perfusion changes during seizures were first observed in the 1930s. Single Photon Emission Computed Tomography (SPECT) was developed in the 1970s, and tracers suitable for the imaging of regional cerebral perfusion (rCP) became available in the 1980s.

Transthyretin amyloid cardiomyopathy in aortic stenosis patients scheduled for transcatheter aortic valve implantation

ESC Heart Failure, EarlyView.
Abbreviations: TAVI, transcatheter aortic valve implantation; ATTR‐CM, transthyretin cardiac amyloidosis. We aimed to diagnose occult ATTR‐CM in patients with severe aortic stenosis undergoing TAVI using bone scintigraphy. We verified a diagnosis of ATTR‐CM in 8 of 171 (4.7 %) consecutive aortic stenosis patients who underwent TAVI.

Fisher information analysis of list-mode SPECT emission data for joint estimation of activity and attenuation distribution [PDF]

arXiv, 2018
The potential to perform attenuation and scatter compensation (ASC) in single-photon emission computed tomography (SPECT) imaging using only the SPECT emission data is highly significant. In this context, attenuation in SPECT is primarily due to Compton scattering, where the probability of Compton scatter is proportional to the attenuation coefficient ...

ILAE neuroimaging task force highlight: The utility of multimodal neuroimaging in diagnostic and presurgical workup of drug‐resistant focal epilepsy

Epileptic Disorders, EarlyView.
Abstract The ILAE Neuroimaging Task Force publishes educational case reports that highlight basic aspects of neuroimaging in epilepsy, consistent with ILAE's educational mission. In patients with drug‐resistant focal epilepsy who are candidates for surgical intervention, the identification of structural abnormalities is a strong predictor of favorable ...

Tolerability, gastric emptying patterns, and symptoms during the Nottingham Test Meal in 330 secondary care non‐diabetic dyspeptic patients

Neurogastroenterology &Motility, Volume 34, Issue 12, December 2022., 2022
The Nottingham Test Meal is a simple, practical, and well‐tolerated test meal for clinical assessment of gastric emptying in patients with dyspepsia. A range of abnormal gastric emptying patterns for a typical cohort of patients using this meal are presented in this graphical abstract.

Gastric sensorimotor function and its clinical measurement

Neurogastroenterology &Motility, Volume 34, Issue 12, December 2022., 2022
Although gastric physiology is complex, recent progress has been encouraging, with the heterogenous pathophysiology of gastric symptoms continuing to be unraveled, and new techniques for evaluating gastric function and symptoms emerging. Perspectives are provided on accommodation testing, gastric emptying, measuring gastric myoelectrical activity ...

Intracranial stimulation for pediatric refractory epilepsy: A single institutional experience using evolving therapies

Epilepsia Open, EarlyView.
Abstract Objective Neuromodulation for pediatric refractory epilepsy (PRE) is preferred when the seizure onset zone is not amenable to surgical resection, due to multifocal onset or involvement of eloquent cortex. Given its rapidly evolving landscape, we describe our institutional experience with neurostimulation therapies including deep brain ...
