Authors: Jiao J, Droste R, Drukker L, Papageorghiou AT, Noble JA Abstract Recent advances in deep learning have achieved promising performance for medical image analysis, while in most cases ground-truth annotations from human experts are necessary to train the deep model. In practice, such annotations are expensive to collect and can be scarce for medical imaging applications. Therefore, there is significant interest in learning representations from unlabelled raw data. In this paper, we propose a self-supervised learning approach to learn meaningful and transferable representations from medical imaging video with...

Authors: Droste R, Chatelain P, Drukker L, Sharma H, Papageorghiou AT, Noble JA Abstract Anatomical landmarks are a crucial prerequisite for many medical imaging tasks. Usually, the set of landmarks for a given task is predefined by experts. The landmark locations for a given image are then annotated manually or via machine learning methods trained on manual annotations. In this paper, in contrast, we present a method to automatically discover and localize anatomical landmarks in medical images. Specifically, we consider landmarks that attract the visual attention of humans, which we term visually salient landmarks...

Authors: Chick G, Victor J, Hollevoet N Abstract Benign peripheral nerve tumours are rare lesions. The surgical treatment and clinical outcomes depend on the resectability. The aim of this retrospective study was to identify clinical or radiological features that may predict the surgical technique that should be used to improve clinical outcome. Eighty-two patients were diagnosed with solitary benign peripheral nerve tumours. Fifty-five tumours were surgically resectable, and 27 were nonresectable. Pre-operative magnetic resonance imaging and ultrasound were used, which were predictive of the neural origin of the t...

Purpose of review The essential role of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) in lung cancer diagnosis and staging is now well established. With a growing body of evidence seen over the last decade, the objective of this article was to review the newest findings, provide evidence-based guidance to clinicians and identify areas for future research related to EBUS-TBNA and staging in lung cancer. Recent findings Recent literature regarding EBUS-TBNA for lung cancer staging was reviewed, with a focus on evidence published subsequent to the 2016 guideline on technical aspects of EBUS...
