BoneXpert – A mature AI product

In April, Kicky van Leeuwen et al presented the paper Artificial intelligence in radiology: 100 commercially available products and their scientific evidence. It got quite some attention, because it documents what many have suspected, namely, that most AI products lack sufficient publications.

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.

BoneXpert validated in Afghan toddlers

A new paper by Suma Uday et al reports the use of BoneXpert to study bone age and BHI in deprived Afghan children of age 1.5-2.5 y. This validates version 3 of BoneXpert, which extends the bone age range down to new-borns – the older version of BoneXpert was valid only down to 2.5 years.

Celebrating 50 BoneXpert publications on PubMed

Searching PubMed with “BoneXpert” yields 50 publications until the end of 2020.

Until 2017, there were 31 publications of which 18 were coauthored by Visiana.

In 2018-20, there were 19 publication, and none of the them were coauthored by Visiana, marking a shift towards independent validation studies.

30 of the 50 publications were on bone age, 5 were on adult height prediction and a surprisingly large number, 15, were on the Bone Health Index.

New Adult Height Predictor supports three ethnicities

The Bayley-Pinneau method for adult height prediction (AHP) from age, bone age and height was developed in 1952 based on American white children. In 2009, the method was modernised through the BoneXpert AHP based on automated bone age, better math and more recent Caucasian longitudinal studies.

We are happy to present an extension of the method to cover three major ethnicities: Caucasians, Asians and Africans.
