Background: Up to 20% of resting echocardiograms obtained are suboptimal leading to further downstream testing and delays in diagnosis. Contrast enhanced echocardiography is well established and endorsed for use by the American Society of Echocardiography (ASE) in clinical scenarios when 2 or more adjacent wall segments are not well visualized; however, varied institutional protocols and practices in place limit such use due to increased time and personnel needed to obtain such imaging.
Methods: The purpose of this study was to determineif sonographer administered echo contrast led to decreased time to complete inpatient echocardiography exams when compared to the current institutional policy of having a registered nurse perform administration of contrast via a case-control approach. Sonographers received a one-day training course on the techniques for contrast administration. Baseline completion times (time from 1st image to last image) were reviewed in studies from March 2015 to May 2015. Sonographers who received training began self-administration of contrast the first week of June 2015. After a familiarization period, study completion times were recorded from September 2015 to December 2015 and compared to those during the baseline phase. Sonographers were not informed that they were being monitored. Patients and the public were not involved in the design or conduct of our study.
Results: A total of 320 patients were included for analysis. Time spent obtaining contrast enhanced imaging was not significant between the two groups (p = 0.67). Time spent to complete each echocardiogram (time from first echocardiogram image to the last contrast enhanced echocardiogram image) was significant between the two groups (37.5 ± 10.9 min sonographer administered v 49.6 ± 12.5 min in nurse administered group, p < 0.001).
Conclusion: Utilizing a sonographer administered echo enhancement protocol results in reduced over 12 min of time saved per study.

Intracardiac echocardiography (ICE) has been used to guide radio-frequency catheter ablation (RFCA) for better catheter navigation and less radiation exposure in treating atrial fibrillation (AF). This retrospective cohort study enrolled 227 AF patients undergoing ICE- or traditional fluoroscopy (TF)-guided RFCA for AF in a tertiary hospital. ICE was used more often in patients with atrial tachycardia [odds ratio (OR) 3.

Failure to predict stroke promptly may lead to delayed treatment, causing severe consequences like permanent neurological damage or death. Early detection using deep learning (DL) and machine learning (ML) models can enhance patient outcomes and mitigate the long-term effects of strokes. The aim of this study is to compare these models, exploring their efficacy in predicting stroke.

Autonomous vehicles, often known as self-driving cars, have emerged as a disruptive technology with the promise of safer, more efficient, and convenient transportation. The existing works provide achievable results but lack effective solutions, as accumulation on roads can obscure lane markings and traffic signs, making it difficult for the self-driving car to navigate safely. Heavy rain, snow, fog, or dust storms can severely limit the car's sensors' ability to detect obstacles, pedestrians, and other vehicles, which pose potential safety risks.

Liver function affects the prognosis of patients with hepatocellular carcinoma (HCC). This study aimed to investigate the prognostic impact of the functional liver imaging score (FLIS), assessed using gadoxetic acid-enhanced magnetic resonance imaging, on long-term outcomes following hepatectomy for HCC. The FLIS was assessed in 235 patients who underwent initial hepatectomy for HCC.
