”At the Department for Growth and Reproduction, we have a large number of children with tall or short stature. As part of the examination, we use BoneXpert to determine skeletal maturity and make a qualified prediction of the final height. Many of these patients do not require treatment, but it is important to rule out any underlying pathologies as the cause of their disrupted growth.

As a national research centre of excellence, we investigate the effects of GH and IGF-I on growth, glucose metabolism and body composition in children and adults and the impact of genetic variations in the GH and SHOX genes. We have worked with Visiana in the development of BoneXpert bone age and height prediction from an early stage. Today, BoneXpert is an invaluable tool in our clinical practice.”

– Anders Juul, clinical professor and head at the Department of Growth and Reproduction, Rigshospitalet, Copenhagen University Hospital, Denmark.



“When we used the old atlas, the time taken to perform bone ages manually meant that they would often sit unreported for a while. Also, the variability between follow-up bone ages meant needing to check previous results sometimes. With BoneXpert, we have a system that accurately measures trends in bone age. The ease of bone age reporting is fantastic and bone age studies no longer wait to be reported.”  

 – Dr. Jeremy Jones, consultant paediatric radiologist, Royal Hospital for Sick Children, Edinburgh, United Kingdom



 “After switching to BoneXpert, we are getting more consistent bone age ratings than we did with the atlas.

We let BoneXpert process all films of the left hand for bone age determination that were already reported by radiologists. We looked further at the films in which there was more than 12 months’ discrepancy between BoneXpert and the radiologist. There were 20 discrepancies. In 19 cases, BoneXpert was right.

I am very satisfied BoneXpert, and would recommend the system for anyone with a large number of requests for bone age. BoneXpert is not moody, always bright awake and never distracted.”

Dr. Erik Beek, paediatric radiologist, UMC Utrecht, Netherlands




 “Using the G&P atlas can lead to different interpretations, particularly when there are no experienced paediatric radiologists available to read the studies. Especially in longitudinal follow-up this can lead to conflicting reporting. Having been involved in validation studies I knew that, as long as the hand has a normal anatomy, I can trust the system. The installation was easy, and BoneXpert gives consistent results – I haven’t restudied radiographs after making the switch.BoneXpert is more consistent and not influenced by human factors such as experience, time of day and mood. I'm happy to use it and would certainly recommend it to radiologists who have to read a substantial number of bone age studies.”

- Prof. dr. Rick. R. van Rijn, paediatric radiologist, Academisch Medisch Centrum Amsterdam, The Netherlands


“The rating of bone age manually was rather time consuming and not very exact. In my hospital more than thousand bone age ratings are done yearly. A lot of time has been saved in the department with a large bulk of these studies. BoneXpert is also a useful tool for the less experienced radiologist and a way to teach manual rating.


In the beginning I double checked BoneXpert results with manual ratings. However, there is literature available that shows the reliability of the method. I also supervised a small study comparing the BoneXpert ratings with the calendar age of Finnish children who had been imaged for trauma. We found very good correlation.”

- Dr. Kirsi Lauerma, radiologist, Helsinki University Hospital, Helsinki, Finland


“Our bone ages were being reported by a single staff member who became unwell and was unable to provide these time-consuming exams consistently. We were relieved to switch to an automated system, supported by robust research. BoneXpert integrates with our local PACS and has given us rapid turnaround and improved consistency. In fact, our radiologists have stopped doing bone ages manually now.”

– Dr. Andrew Watt, Consultant Paediatric Radiologist; Deputy Clinical Director, Dept of Diagnostic Imaging, The Royal Hospital for Sick Children, Glasgow, United Kingdom



"Bone age is often a chore for radiologists who don't do them that often and have to refer to an atlas for 20 minutes per case! BoneXpert is a major advance in the assessment of children’s bone age and bone health. Since we introduced it into our clinical service last year it has reduced the radiologists workload and provided reliable and immediate reports for our clinicians.”  

– Dr. Benjamin Jacobs, consultant paediatrician, Royal National Orthopaedic Hospital, Stanmore, UK




La valutazione dell'età ossea tramite atlante GP è viziata da grande variabilità intra e inter osservatore. BoneXpert è preciso, rapido, riproducibile e affidabile rispetto alla valutazione su atlante.
L’età ossea è rapidamente calcolata in automatico dal programma BE e il risultato viene “incollato” direttamente sul referto. Ha velocizzato la refertazione che è oggettiva.
L’istallazione è stata molto semplice e rapida. Non si sono mai verificati conflitti tra il software BA e gli altri software nativi
La velocità di refertazione consente di risparmiare ore di lavoro annuali del medico specialista radiologo che può essere quindi impiegato in altra attività/refertazione.”
