A system has been developed for the registration and combined display of the X-ray image and isotope bone scan. This system has been evaluated by prospectively studying 23 patients who were referred for suspected injury of the wrist. The registration system has an inherent precision for registration of about 1 mm. When patient positioning errors are included, this increases to about 4 mm. Two observers evaluated the sets of images prior to registration and after registration and combined display. They judged that in 16 out of 17 cases judged abnormal (observer 1) and 12 out of 18 cases judged abnormal (observer 2), the registration technique improved localization of a lesion. One case was rejected as registration was not possible due to incorrect positioning of the hand
