TLDR
Flow-sensitive 4D MR imaging may constitute a promising, alternative technique to Doppler US for evaluating hemodynamics in the portal venous system of patients with liver cirrhosis and may be a means of assessing pathologic changes in flow characteristics.Abstract:
Flow-sensitive four-dimensional MR may be an alternative to Doppler US as a noninvasive and standardized technique, supplying information about portal venous hemodynamics and pathologic changes in flow characteristics in patients with liver cirrhosis.read more

4D flow MRI
TL;DR: This review intends to introduce currently used 4D flow MRI methods, including Cartesian and radial data acquisition, approaches for acceleratedData acquisition, cardiac gating, and respiration control, and an overview over the potential this new imaging technique has in different parts of the body from the head to the peripheral arteries.
Journal ArticleDOI
4D flow imaging with MRI
TL;DR: The purpose of this review is to describe the methods used for 4D flow MRI acquisition, post-processing and data analysis and provide an overview of the clinical applications of 4D Flow MRI, which includes a review of applications in the heart, thoracic aorta and hepatic system.

TL;DR: The combination of highly efficient spiral sampling with dynamic compressed sensing results in major acceleration for 4D flow MR imaging, which allows comprehensive assessment of abdominal vessel hemodynamics in a single breath hold.
Journal ArticleDOI
Comparison of blood flow velocity quantification by 4D flow MR imaging with ultrasound at the carotid bifurcation.
TL;DR: 4D flow MR imaging allowed for an accurate measurement of blood flow velocities in the carotid bifurcation of both volunteers and patients with only moderate underestimation compared with US.

The measurement of observer agreement for categorical data
J. R. Landis,Gary G. Koch +1 more
TL;DR: A general statistical methodology for the analysis of multivariate categorical data arising from observer reliability studies is presented and tests for interobserver bias are presented in terms of first-order marginal homogeneity and measures of interob server agreement are developed as generalized kappa-type statistics.

Transection of the oesophagus for bleeding oesophageal varices
TL;DR: Emergency ligation of bleeding oesophageal varices using the Milnes Walker technique was performed in 38 patients, and in patients with good preoperative liver function this rose to 71% and the simple scoring system for grading the severity of disturbance of liver function was found to be of value in predicting the outcome of surgery.

TL;DR: The results indicate that displacement patterns corresponding to cyclic displacements smaller than 200 nanometers can be measured and suggest the feasibility of a medical imaging technique for delineating elasticity and other mechanical properties of tissue.

Non-invasive evaluation of liver fibrosis using transient elastography ☆
TL;DR: TE appears to be an excellent tool for early detection of cirrhosis and may have prognostic value in this setting and could be useful for monitoring fibrosis progression and regression in the individual case, but more data are awaited for this application.
