BoneXpert has been introduced in four new countries by a purchase from these institutions:
There are now in total 80 hospitals using BoneXpert for at least 100 analyses per year.
Two new papers report the use of BoneXpert to assess rheumatoid and psoriatic arthritis. They exploit the recent extension of BoneXpert’s measurement of cortical thickness in the metacarpals to adults.
The upcoming release of BoneXpert version 2.4 (version 2.4.5.1, released Dec 28) extends the Greulich-Pyle bone age range up to 19 years for boys and 18 years for girls. Previous versions were less reliable in the bone age range 17-19 for boys and 15-18 for girls. The validation of this extension is reported in the International Journal of Legal Medicine.
Wilhelm Conrad Röntgen’s first public presentation of the new X-rays took place on the 23rd of January 1896 in Würzburg.
The Swiss anatomist Albert von Kölliker volunteered to have his hand X-rayed during the lecture, and the resulting image has now been analysed with a new version of BoneXpert, presented in the Archives of Osteoporosis
The number of hospitals having purchased a license to BoneXpert and doing at least 100 analyses per year has risen to 60.
Pediatric Radiology has published a paper on validation of adult height prediction (AHP) in the Paris longitudinal study of children born 1953-58.
The BoneXpert adult height predictor, based on the 2009 JCEM article, has been extended, so that it now plots the entire predicted growth path in a growth chart. It also predicts the age of peak height velocity.
Thirty-two hospitals have now purchased a license to BoneXpert, a doubling since November 2012.
ACTA Radiology’s November 2013 issue is devoted to invited articles on pediatric radiology and features a review entitled “Bone age assessment: automated techniques coming of age?”.
