Unsupervised Contrastive Learning of Image Representations from Ultrasound Videos with Hard Negative Mining [PDF]
arXiv, 2022 Rich temporal information and variations in viewpoints make video data an attractive choice for learning image representations using unsupervised contrastive learning (UCL) techniques. State-of-the-art (SOTA) contrastive learning techniques consider frames within a video as positives in the embedding space, whereas the frames from other videos are ...

Annals of Gastroenterological Surgery, EarlyView.The calibration plots of the updated risk models for the endpoints were analyzed in each cohort. The predicted probability of each endpoint matched the observed probability in the development and validation cohorts. Abstract Aim Risk prediction models for mortality, severe postoperative complications, and postoperative pancreatic fistula in patients ...

AbdomenAtlas-8K: Annotating 8,000 CT Volumes for Multi-Organ Segmentation in Three Weeks [PDF]
arXiv, 2023 Annotating medical images, particularly for organ segmentation, is laborious and time-consuming. For example, annotating an abdominal organ requires an estimated rate of 30-60 minutes per CT volume based on the expertise of an annotator and the size, visibility, and complexity of the organ.

Indocyanine green (ICG) fluorescence in robotic hepatobiliary surgery: A systematic review
The International Journal of Medical Robotics and Computer Assisted Surgery, Volume 19, Issue 1, February 2023., 2023 Abstract Background Indocyanine green fluorescence (ICG‐F) stains hepatic tumours and delineates vascular and biliary structures in real‐time. We detail the efficacy of ICG‐F in robotic hepatobiliary surgery. Methods PubMed, EMBASE, Web of Science, and Cochrane Central were searched for original articles and meta‐analyses detailing the outcomes of ICG ...

Gall Bladder Cancer Detection from US Images with Only Image Level Labels [PDF]
arXiv, 2023 Automated detection of Gallbladder Cancer (GBC) from Ultrasound (US) images is an important problem, which has drawn increased interest from researchers. However, most of these works use difficult-to-acquire information such as bounding box annotations or additional US videos. In this paper, we focus on GBC detection using only image-level labels. Such

Annals of Gastroenterological Surgery, EarlyView.The study aim was to clarify how nutrition was managed in patients based on surgical site during the first 7 d after gastrointestinal cancer surgery. As results, oral intake after gastrointestinal cancer surgery started earliest in patients having liver surgery and latest in patients having esophageal surgery.
