BoneXpert – the most widely used radiology AI in the Netherlands in 2022

At ECR, Kicky van Leeuwen of Radboud University Medical Center gave the talk “The rise of artificial intelligence solutions in radiology departments in the Netherlands”.

Van Leeuwen and her co-workers have asked the 69 radiology departments in the Netherlands about their adoption of AI.

They found that the most widely used methods are the ones shown here:

The most popular method is BoneXpert from Danish Visiana, used in 9 departments.

The second use case is detection of lung nodules in CT scans, used by 8 departments – the product Veye Lung Nodules was developed by the Dutch company Aidence (recently acquired by RadNet).

The third-most used method is stroke – left-ventricle occlusion or intracranial haemorrhage detection on CT and CT angiography – probably StrokeViewer from the Dutch vendor Nicolab.

 

The investigators also inquired about the obstacles for adopting AI and found that the most important were “cost” and “IT”. So, one can infer that the most widely used methods have a favourable balance between cost and benefit, and carry a low IT burden.

Only 3 departments reported use of an “AI platform”.

This talk was also highlighted by AuntMinnie

 

Note that the survey did not obtain 100% response rate, and indeed Visiana’s records show that there are 14 customers of BoneXpert in the Netherlands, each performing between 100 and 1300 analyses per year.

United States patent granted to Visiana

The US patent office has granted Visiana a patent for the invention of an image processing method.

A key element of BoneXpert is to locate each bone accurately as a first step in the bone age analysis. Visiana has invented a new method to locate a landmark, e.g. the tip of a bone. About 100 examples are needed for the machine learning method, which trains a decision tree to predict the location from a nearby image patch. The predictions from more than 300 patches are placed in a voting map, and the peak of votes yields the landmark location with subpixel accuracy. The figure shows the voting map for finding the tip of a distal phalanx.

The invention could also be useful in land vehicles and smartphones.

 

Bone Health Index demonstrates relation to fractures in Klinefelter children

A study published in Journal of the Endocrine Society by Vogiatzi and Ross of Jefferson University Hospital in Philadelphia, followed 90 Klinefelter boys, half of which were treated with Oxandrolone – an anabolic steroid.

(Males have one X and one Y chromosome and females have two X chromosomes. Klinefelter boys have two X and one Y chromosome, i.e. XXY. The incidence Klinefelter Syndrome is 1 of 800 boys.)

Financial impacts of BoneXpert; Webinar highlights with Prof. Amaka Offiah and Dr. Alistair Calder

Visiana held its BoneXpert webinar to explore the automation of the processes in radiology that is currently taking place in the UK.

Presenters were Professor Amaka Offiah, and Dr. Alistair Calder who presented their views and findings when using BoneXpert in the daily routine at Sheffield University Hospital and at Great Ormond Street Hospital in London.

The webinar was well-attended, and here are a some highlights.

Almost full house in Scandinavia

Visiana welcomes the South-Eastern Norway Regional Health Authority (Helse Sør Øst) as a BoneXpert customer. Helse Sør Øst includes Norway’s capital Oslo, and the authority provides health care for 56% of Norway’s population.

Around 50 hospitals in Scandinavia are performing more than 100 bone age analyses per year. With the addition of Helse Sør Øst, BoneXpert is licensed to all of these hospitals with the exception of 1 hospital in Norway, 2 in Sweden and 1 in Finland.
