Bone age in years and months
Review the AI-assisted estimate on the Greulich–Pyle scale with the original hand–wrist image.
NEW IN RADEZE AI · HAND & WRIST X-RAY
Bone age.
Clearly mapped.
Ready for review.
Bring skeletal maturity into focus. Review an AI-assisted bone-age estimate alongside the hand X-ray, mapped landmarks and a structured report.

Illustrative values
Hand image from the supplied example; display values are illustrative.
Input
Hand–wrist radiograph with verified age, sex and laterality. Standard bone-age assessment uses the left hand.
Output
Estimated bone age, chronological-age comparison, normal-range context and a structured report for review.
Visual reference
Hand skeleton map with finger, metacarpal and phalangeal landmarks.

Recreated website illustration, not a live analysis. This example film is labelled RT HAND AP; confirm laterality before assessment. Reference standards use the left hand. No patient identifiers are displayed.
From image to structured output
A clearer view of skeletal maturity.
Age difference in context
Compare estimated bone age with chronological age, supported by the report’s age-reference chart.
Normal range and SD score
Review the reported normal range and standard-deviation score against the stated reference population.
A structured review document
Bring the estimate, impression, hand map and reference-hand comparison together for clinician review.
Age-reference context uses healthy US children. Reference-hand images in the report are from the USC Digital Hand Atlas and are distinct from Greulich–Pyle atlas plates. Clinical applicability must be assessed for the individual patient.

How it fits
From hand X-ray
to reviewed report.
Confirm image and demographics
Check the hand–wrist view, laterality, chronological age and sex before assessing the output.
Read estimate and visual context
Review the bone-age estimate, reference range and uncertainty alongside the image and hand skeleton map.
Apply clinical judgment
Confirm applicability, correlate with the clinical history and complete the final interpretation.
Common questions
About Bone Age AI.
What does Bone Age AI assess?
It supports skeletal maturity assessment from a hand–wrist radiograph. The supplied report includes estimated bone age, chronological-age comparison, age-reference context, a hand skeleton map and reference-hand images.
Are the website visual and values a live result?
No. The hand map is a recreated website illustration based on the supplied example. Displayed ages are illustrative. The controls change the overlay only; this page does not analyse uploaded X-rays.
What do the hand-map lines and dots represent?
The paths connect finger and metacarpal landmarks. Dots identify joints and endpoints. Labels distinguish digits I–V and the metacarpal and phalangeal segments; they do not represent a separate bone-age estimate for each bone.
Does this replace radiologist review?
No. The output requires source-image verification and clinical correlation. The clinician remains responsible for the final interpretation, including any pathology visible on the radiograph.
