Regularized ultrasound phantom-free local Attenuation Coefficient Slope (ACS) imaging in homogeneous and heterogeneous tissues
(Institute of electrical and electronics engineers, 2022-11-01)
Attenuation map or measurements based on local
attenuation coefficient slope (ACS) in quantitative ultrasound
(QUS) has shown potential for diagnosis of liver steatosis. In liver
cancers, tissue abnormalities and tumors ...
Ultrafast quantitative ultrasound and shear wave elastography imaging of in vivo duck fatty livers
(Institute of electrical and electronics engineers, 2019-12-08)
Multi-parametric ultrasound imaging is a
promising tool for quantification of nonalcoholic fatty
liver disease. In this work, a protocol of plane wave
quantitative ultrasound (QUS) and shear ...
Morphologic evaluation of ruptured abdominal aortic aneurysm by 3D modeling
(2012-12-03)
Abdominal aortic aneurysm (AAA) is defined as a dilatation of the abdominal aorta exceeding the normal diameter by more than 50%. The standard and widely used approach to assess AAA size is by measuring the maximal diameter ...
Feasibility of shear wave sonoelastography to detect endoleak and evaluate thrombus organization after endovascular repair of abdominal aortic aneurysm
(Springer, 2020-03-04)
Purpose
To investigate the feasibility of shear wave sonoelastography (SWS) for endoleak detection and thrombus characterization of abdominal aortic aneurysm (AAA) after endovascular repair (EVAR).
Materials and ...
White paper of the Society of Abdominal Radiology hepatocellular carcinoma diagnosis disease-focused panel on LI-RADS v2018 for CT and MRI
(Springer, 2018-08-28)
The Liver Imaging and Reporting Data System (LI-RADS) is a comprehensive system for standardizing the terminology, technique, interpretation, reporting, and data collection of liver imaging with the overarching goal of ...
Test-retest reliability of clitoral blood flow measurements using color Doppler ultrasonography at rest and after a pelvic floor contraction task in healthy adult women
(Wiley, 2018-06-28)
Aims: Test-retest reliability assessment of the dorsal clitoral artery's blood flow at rest and
after muscle activation has never been documented. If this outcome measure is to be used
in conditions impeding vascularity, ...
Impact of contrast injection and stent-graft implantation on reproducibility of volume measurements in semiautomated segmentation of abdominal aortic aneurysm on computed tomography
(Springer, 2014-05-07)
Purpose To assessthe impact of contrast injection and stent-graft implantation on feasibility, accuracy, and
reproducibilityof abdominal aortic aneurysm (AAA) volume and maximaldiameter (D-max) measurements
using ...
Reproducibility of abdominal aortic aneurysm diameter measurement and growth evaluation on axial and multiplanar computed tomography reformations
(Springer, 2011-08-24)
Purpose: Compare different methods measuring abdominal aortic aneurysm (AAA)
maximal diameter (Dmax) and its progression on multi-detector computed tomography
scan (MDCT).
Materials and Methods: Forty AAA patients with ...
Impact of temporal resolution and motion correction for dynamic contrast-enhanced MRI of the liver using an accelerated golden-angle radial sequence
(IOP Publishing, 2020-04-17)
This paper presents a prospective study evaluating the impact on image quality and quantitative dynamic contrastenhanced (DCE)-MRI perfusion parameters when varying the number of respiratory motion states when using ...
Machine learning based on quantitative ultrasound for assessment of chronic liver disease
(Institute of electrical and electronics engineers, 2020-11-17)
Chronic liver disease (CLD) is a highly prevalent condition characterized by the coexistence of histopathological changes, including liver steatosis, inflammation and fibrosis. Based on a multi-parametric approach, the ...
