Deep learning enables automatic radiotherapy planning

January 10, 2019 -- A multi-institutional team has developed an automated treatment planning system for intensity-modulated radiation therapy based on 3D dose prediction and dose distribution-based optimization. The researchers demonstrated that the deep-learning-based method shows promise for generating highly individualized radiotherapy plans optimized for precision and quality. Discuss

Spanish group scoops top prizes for work in advanced MRI

January 9, 2019 -- Radiologists from a small city in southern Spain that is famous for its olive oil and medieval fortresses have collected two prestigious awards for their groundbreaking research in the emerging field of diffusion tensor imaging. Discuss

German team investigates novel method to detect gadolinium

January 8, 2019 -- Researchers from Erlangen, Germany, have looked at the possibility that significantly lower T1 relaxation times can confirm the presence of gadolinium in the brains of patients who have undergone multiple contrast-enhanced MRI scans. They published their findings online on 1 January in Radiology. Discuss

Austrians spell out how to succeed with machine learning

January 7, 2019 -- It's vital for radiologists to understand the basic principles of machine learning and the differences between supervised and unsupervised learning, as well as to appreciate the importance of data quality, according to award-winning research from Austria. Discuss

Flashback: The grumpy old man in Vienna

January 7, 2019 -- As ECR 2019 looms large and the attention of the medical imaging community shifts to Vienna, now is a great time to enjoy this classic video comedy sketch from March 2006. U.K. radiologist Dr. Paul Dubbins is desperate to find something to complain about at the congress and the Austrian capital -- but he fails miserably. Discuss

Where is AI making the difference in radiology today?

January 4, 2019 -- Artificial intelligence (AI) promises to reduce costs and improve clinical outcomes, and it can provide useful support tools that can be integrated into current workflow, PACS, medical imaging hardware, and healthcare clouds, writes industry expert Gene Saragnese. Discuss

French radiology responds strongly to 'disdainful' criticism

January 3, 2019 -- France's National Council of Radiology has reacted angrily to a series of negative comments made about the profession by an expert in infectious diseases. The remarks were made in a recent editorial in the weekly political and news magazine Le Point. Discuss

Global survey finds wide variation in CT radiation dose

January 2, 2019 -- Substantial variation in radiation dose used for CT scans is mainly due to how the scanners are used by medical staff rather than differences in the patients scanned or the machines used, according to an extensive international study published on 2 January in BMJ. Discuss

What does the future hold for imaging of osteoarthritis?

January 2, 2019 -- Radiography, MRI, and ultrasound all have a role to play in osteoarthritis imaging, but what are the pros and cons of using each modality, and how is hybrid imaging likely to transform this field? Three international musculoskeletal experts provide some answers. Discuss
