How to Improve Diagnostic AI in Medicine?

2021 08 Nov

The University of Johannesburg recently publicised a study published in Informatics in Medicine Unlocked examining how to improve machine learning (ML) algorithms for healthcare use. Algorithms can better identify healthy individuals since they are often trained on ‘unbalanced’ datasets containing more healthy than sick individuals. Since fewer data... Read more

Automated Triaging of MRIs Rules Out Cancer in Dense Breasts

2021 08 Oct

Mammography provides early detection when breast cancer treatments are more successful. Unfortunately, mammography is less sensitive in women with dense than with fatty breast tissue. This is unfortunate because the breast cancer risk is three- to six times higher in dense rather than fatty breast tissue and two times higher than that of the average... Read more

Ensuring Safety and Efficacy in Adaptive AIs for Radiology

2021 04 Oct

A recent article, published 30 September in the Journal of the American College of Radiology , explored post-regulatory pharmacovigilance issues associated with radiological practice AIs and strategies for choosing ideal solutions.   AI algorithms in clinical use are increasing. The US FDA has cleared over 100 commercially available AI algorithms... Read more

Machine Learning Process Flags Actionable Reports in Radiology Department

2021 23 Sep

An automated detection method can help clinicians identify overlooked actionable findings in radiology reports and avoid costly delays to patient care. Therefore, one University of Tokyo research team recently assessed four methods for flagging “actionable” results from free-text in reports from their radiology department. Their analysis compared...

Timely Alerts Reduce Mortality

2020 13 Nov

An automated alert system that analyses electronic health records (EHR) can help identify high-risk in-hospital patients needing interventions by rapid response teams, resulting in decreased mortality, says a Kaiser Permanente-led study (Escobar et al. 2020).   You might also like: AI Tool Helps to Reduce COVID-19 Mortality  ...

Applying ML to Study India’s COVID-19 Policies

2020 24 Sep

The nudge theory is known to be useful in effecting behaviour change. Using the nudge of ‘nationalism’ in the fight against COVID 19, the government of India was able to motivate its large population to abide by lockdown rules and basic health protocols (e.g. wearing of face masks and frequent handwashing).   You might also like: AI Tool...

Machine-Learning-Based Prediction Models for AKI

2019 23 Aug

Acute Kidney Injury (AKI) is a common occurrence for critically ill patients in the ICU, and its early diagnosis has proven to be challenging. The accuracy of the online, machine-learning-based prediction model, AKIpredictor , was analysed for its use in a clinical setting.   The study, which took place over five ICUs in Belgium, compared the predictions...

The promise of AI in radiology

2019 30 Jan

Needless to say, radiology plays a critical role in healthcare delivery. It is rare for a patient to pass through a hospital without requiring the opinion of a radiologist somewhere along their journey – be it in triaging patients in the ER , assessing the need for treatment, or evaluating the effectiveness of treatment.  Equally important is...
