Accuracy of Teleradiology in Skeletal Disorders: Solitary Bone Lesions and Fractures

Abstract

To evaluate the diagnostic accuracy of digitized film radiography and digital teleradiology for detecting bone fractures and for studying solitary bone lesions, we examined 633 single radiographs from 373 patients (159 with solitary bone lesions, 123 with fractures and 91 without pathology). Radiographs were digitized using a commercial teleradiology workstation and transmitted to a local hospital over a standard telephone line. Images were reviewed by two groups of three experienced radiologists. Receiver operating characteristic (ROC) curves were analysed for conventional films, digitized images and transmitted teleradiology images. No significant differences were found among readers for the evaluation of bone fractures and solitary bone lesions. Teleradiology systems permit remote expert consultation, and telediagnosis therefore is a powerful tool in telemedicine.
