Implementation of the KTAS changed admission and disposition patterns and reduced the LOS and mortality in the ED.

Implementation of point-of-care ultrasonography (POCUS)-assisted physical examination (PE) in emergency departments (EDs) was conducted in the ED of an urban tertiary teaching hospital. This study examines the effect of POCUS implementation in emergency medicine departments by using a systematic education program on image acquisition to analyze decision making.Educating staff on POCUS involved a technique related to image acquisition and then accurately diagnosing subsequent POCUS results. The q

<b>Background:</b> NIRSIT, a functional near-infrared spectroscopy (fNIRS) device with 204 channels, can measure oxyhemoglobin (HbO2) and deoxyhemoglobin (HbR) in non-pulsatile blood flow non-invasively using the absorption difference between HbO2 and HbR at a wavelength of 700-1,000 nm and can display the perfusion status in real time. <b>Objective:</b> We applied NIRSIT to patients with stroke to evaluate the usefulness of NIRSIT as an fNIRS device for the early detection of stroke. <b>Methods

This study aims to enhance breast cancer detection accuracy through an AI-driven ultrasound tool, Vis-BUS, developed by Barreleye Inc., Seoul, South Korea. Vis-BUS incorporates Lesion Detection AI (LD-AI) and Lesion Analysis AI (LA-AI), along with a Cancer Probability Score (CPS), to differentiate between benign and malignant breast lesions. A retrospective analysis was conducted on 258 breast ultrasound examinations to evaluate Vis-BUS's performance. The primary methods included the application

These findings indicate that the location of the LV during cardiopulmonary resuscitation might be in the middle of the sternum if the patient is treated in the EAD position.

Implementation of a practice guideline involving early feeding and discharge after reduction of intussusception resulted in a reduced LOS from reduction of intussusception in the PED and was not associated with recurrence of intussusception.

Children feature more active cellular division and a smaller body area, which leads to a greater radiation dosage accumulation. We tried to reduce radiation hazards by reducing unnecessary radiological studies in a pediatric emergency department (PED) through the radiation reduction campaign.Our campaign involved a reduction from 2 (erect and supine) to 1 ordered abdominal plain radiograph (erect). This quasi-experimental, uncontrolled before-and-after study aimed to evaluate the campaign effect

It aimed to investigate the incidence and final diagnosis of hyperintense acute reperfusion marker (HARM) signs in patients initially suspected of having a transient ischemic attack (TIA).In retrospective manner, a series of consecutive series of patients who arrived at the emergency department and was initially assessed as TIA within 12 hours of symptom onset between July 2015 and December 2016 were enrolled. Conventional magnetic resonance imaging protocol including diffusion-weighted imaging

Non-alcoholic fatty liver disease (NAFLD), prevalent among conditions like obesity and diabetes, is globally significant. Existing ultrasound diagnosis methods, despite their use, often lack accuracy and precision, necessitating innovative solutions like AI. This study aims to validate an AI-enhanced quantitative ultrasound (QUS) algorithm for NAFLD severity assessment and compare its performance with Magnetic Resonance Imaging Proton Density Fat Fraction (MRI-PDFF), a conventional diagnostic to

Traditional B-mode ultrasound has difficulties distinguishing benign from malignant breast lesions. It appears that Quantitative Ultrasound (QUS) may offer advantages. We examined the QUS imaging system's potential, utilizing parameters like Attenuation Coefficient (AC), Speed of Sound (SoS), Effective Scatterer Diameter (ESD), and Effective Scatterer Concentration (ESC) to enhance diagnostic accuracy. B-mode images and radiofrequency signals were gathered from breast lesions. These parameters w
