Filter by:Non-Contrast Computed Tomography (NCCT) of the head is the most common imaging method used to assess patients attending the Emergency Department (ED) with a wide range of significant neurological presentations including trauma, stroke, seizure and reduced consciousness. Rapid review of the images supports clinical decision-making including treatment and onward referral. Radiologists, those reporting scans, often have significant backlogs and are unable to prioritise abnormal images of patients with time critical abnormalities. Similarly, identification of normal scans would support patient turnover in ED with significant waits and pressure on resources. To address this problem, Qure.AI has worked to develop the market approved qER algorithm, which is a software program that can analyse CT head to identify presence of abnormalities supporting workflow prioritisation. This study will trial the software in 4 NHS hospitals across the UK to evaluate the ability of the software to reduce the turnaround time of reporting scans with abnormalities that need to be prioritised.
This is a randomized study that will enroll patients scheduled for an endoscopic ultrasound biopsy of a pancreas lesion to be in the heparin or saline group during the procedure. The purpose of this study is to examine the effect of blood contamination, heparin priming of the fine needle biopsies, and pass number on tumor tissue quality in fine needle biopsies. The hypothesis for this study is that fine needle biopsy tissue quality of pancreatic masses decreases with increasing pass number due to blood contamination; this blood contamination can be ameliorated with priming of the needle with an anticoagulant such as heparin.
The aim of this study is to compare endoscopic ultrasound guided-fine needle aspiration (EUS-FNA) with a standard 22-gauge needle using "standard suction", "slow-pull" and "wet suction" for thoracic/abdominal solid/solid-cystic lesions. Investigators intend to compare the effectiveness and safety of the three methods in order to discover the optimized technique for obtaining diagnostic material and making accurate diagnosis.
