The purpose of this study was to evaluate the ability and accuracy of    imaging in the diagnosis of the bone tumors comparing to the results of    pathology.           It was conducted by assessment of the records of 71 patients (between    6-65 years of age) with primary diagnosis of bone tumors referred to the    orthopedy department of Sina and Shariatti hospital in Tehran during two    years (1993-1994) who had completed chart, lab data and radiographic    studies as well as definite pathologic diagnosis. According to radiologic    finding of each patient, three differential diagnosis were made and divided    into the benign and malignant groups and then compared with the result    of pathoogy, using Mc Nemar statistical test. Furthermore the frequency of    bone tumors in these patients was assessed.           Our findings showed that the most frequent benign and malignant    tumors among these patients were giant cell tumor (18.3%) and    Osteosarcoma (5.6%) and Uwing sarcoma(5.6%), respectively. Moreover    the frequency of all the tumors including benign and malignant lesions in    6-25 year old patients was more than other groups. Comparing the radiologic    finding with the result of biopsy showed that if all the three radiological    diagnosis conformed a benign lesion, we can expect the tumor is    benign with the positive pedictive value of 100%. In our study these included    88% of beign tumors and 65% of all the tumors that were reviewed.           We can therefore conduct the diagnosis and therapulic processes in    only one session to avoid further cost and time.
