Comparison of CT-Guided Microwave Ablation of Liver Malignancies with and Without Intra-Arterial Catheter Placement for Contrast Administration.

Background: The aim of this study was to compare microwave ablation (MWA) with and without prior placement of an intra-arterial catheter for the purpose of application of contrast medium (CM).

Methods: 148 patients (45 female, 65.1 ± 14.

Potential diagnostic value of high b-value computed diffusion-weighted imaging in hepatocellular carcinoma.

Aim Of The Study: Over the past few years, diffusion-weighted imaging (DWI) has become an increasingly important diagnostic tool in the diagnosis of liver lesions. The objective of the present study was to evaluate the diagnostic benefit of high b-value computed diffusion-weighted imaging (c-DWI) compared with standard DWI in patients with hepatocellular carcinoma (HCC) and whether there is an association with microvascular invasion (MVI).

Material And Methods: In total, 37 patients with histopathologically confirmed HCC were retrospectively ana-lyzed.

Prognostic relevance of CT-defined body composition in patients with acute bleeding undergoing endovascular embolization.

Objectives: Body composition assessment includes the parameter skeletal muscle mass, subcutaneous and visceral adipose tissue (SAT and VAT). The purpose of this study was to elucidate associations of body composition parameters with mortality in patients with acute bleeding undergoing transarterial embolization (TAE).

Methods: A mixed cohort of patients from 2018 to 2022 with acute bleeding requiring treatment with a TAE was retrospectively evaluated.

Full Quantum Dynamics Study for H Atom Scattering from Graphen.

This study deals with the understanding of hydrogen atom scattering from graphene, a process critical for exploring C-H bond formation and energy transfer during atom surface collision. In our previous work [Shi, L.; 2023, 159, 194102], starting from a cell with 24 carbon atoms treated periodically, we have achieved quantum dynamics (QD) simulations with a reduced-dimensional model (15D) and a simulation in full dimensionality (75D).

Predicting the risk of intensive care unit admission in patients with COVID-19 presenting in the emergency room: Development and evaluation of the CROSS score.

Background: Existing risk evaluation tools underperform in predicting intensive care unit (ICU) admission for patients with the Coronavirus Disease 2019 (COVID-19). This study aimed to develop and evaluate an accurate and calculator-free clinical tool for predicting ICU admission at emergency room (ER) presentation.

Methods: Data from patients with COVID-19 in a nationwide German cohort (March 2020-January 2023) were analyzed.
