Investigating the Correlation between Liver Ultrasound pSWE and Portal Vein Hemodynamics: Preliminary Findings.

Introduction: Portal vein size and hemodynamics can be altered in patients with portal hypertension. Elastography for liver stiffness has been proposed as a potential predictor of portal hypertension. However, the relationship between liver stiffness measured using point shear wave elastography (pSWE) and portal vein diameter and Doppler parameters remains unclear.

Gender and cytoarchitecture differences: Functional connectivity of the hippocampal sub-regions.

Introduction: The hippocampus plays a significant role in learning, memory encoding, and spatial navigation. Typically, the hippocampus is investigated as a whole region of interest. However, recent work has developed fully detailed atlases based on cytoarchitecture properties of brain regions, and the hippocampus has been sub-divided into seven sub-areas that have structural differences in terms of distinct numbers of cells, neurons, and other structural and chemical properties.

B-mode ultrasound characteristics of carotid plaques in symptomatic and asymptomatic patients with low-grade stenosis.

Carotid plaque features assessed using B-mode ultrasound can be useful for the prediction of cerebrovascular symptoms. Therefore, the aim of this retrospective study was to determine the ability of ultrasound B-mode imaging to differentiate between carotid plaques causing less than 50% stenosis in symptomatic and asymptomatic patients. A dataset of 1,593 patients with carotid disease who underwent carotid ultrasound between 2016 and 2021 was evaluated retrospectively between January and April of 2022.

Prevalence and Risk Factors of Carotid Artery Stenosis (CAS) Among Cardiac Surgery Patients.

Introduction: Cardiac disease and carotid atherosclerosis rates have increased in recent years. Carotid artery stenosis (CAS) has been recognized as a high-risk factor of perioperative stroke among cardiac surgery patients.  Aims: The aims of the study are to identify the prevalence and common risk factors of CAS among patients undergoing cardiac surgery that include coronary artery bypass surgery or valvular cardiac surgery.

Inter and intra-examiner reliability of musculoskeletal ultrasound scanning of Anterior Talofibular Ligament and ankle muscles.

Purpose: Although the function of subjects with chronic ankle instability (CAI) has been examined, structural analysis by ultrasound scanning of the structures surrounding the ankle is limited. Before such structural comparisons between injured and uninjured people can be made it is important to investigate a reliable measurement protocol of structures possibly related to CAI. The aim of this study was to investigate the inter-intra examiner reliability of ultrasonic characteristics of selected structures in healthy subjects.

Predicting Intensive Care Unit Admission for COVID-19 Patients from Laboratory Results.

Trends in routine laboratory tests, such as high white blood cell and low platelet counts, correlate with COVID-19-related intensive care unit (ICU) admissions. Other related biomarkers include elevated troponin, alanine aminotransferase, and aspartate transaminase levels (liver function tests). To this end, the aim of this study was to investigate the effect of changes in laboratory test parameters on ward-based and ICU COVID-19 patients.

A web-based cross-sectional study assessing the impact of COVID-19 on the mental health of radiology staff in Saudi Arabia.

The 2019 novel coronavirus pandemic has not only created massive public health issues, it has also produced excessive psychological disorders in healthcare professionals, including radiology staff. The aim of this study is to assess the risk perception and mental health of radiology staff in Saudi Arabia during the COVID-19 pandemic. The researcher asked radiology staff to complete an online Google Forms questionnaire, between June 10, 2020 and June 17, 2020, which contained demographic data and self-designed questions related to anxiety, insomnia, depressive symptoms, and mental health services during the pandemic.

Evaluation of ultrasound point shear wave elastography reliability in an elasticity phantom.

Purpose: To date, limited studies have specifically addressed the reliability of ultrasound point shear-wave elastography (pSWE). Therefore, the aim of the present study was to assess the reproducibility of ultrasound pSWE within and between operators using two ultrasound scanners.

Methods: iU22 and EPIQ7 ultrasound scanners were used to assess the reliability of pSWE measurements of four inclusions [L I (8 kPa), L II (14 kPa), L III (48 kPa), and L IV (80 kPa)] at a depth of 3.

Laboratory Biomarkers Associated with Severity and Mortality of COVID-19.

Background: Corona Virus Disease 2019 (COVID-19) emerged late 2019 and has become a global pandemic. There is an urgent need for identification of biomarkers to predict severity of the disease for early treatment and to avoid mortality especially in high-risk population. Therefore, the aim of this study is to investigate laboratory results in COVID-19 patients in Saudi Arabia to identify potential biomarkers correlated with disease severity.

Ultrasound Characteristics of Foot and Ankle Structures in Healthy, Coper, and Chronically Unstable Ankles.

Objective: Ankle sprains constitute approximately 85% of all ankle injuries, and up to 70% of people experience residual symptoms. While the injury to ligaments is well understood, the potential role of other foot and ankle structures has not been explored. The objective was to characterize and compare selected ankle structures in participants with and without a history of lateral ankle sprain.
