Results The average number of lesions per patient detected before diagnosis was 3.5 ± 2.9 [1-26]. The mean number of lesions was 1 ± 0.9 by radiographs, 2.45 ± 1.7 by isotopic bone scan and 3.12 ± 1.33 by MRI. A total of 193 radiographic lesions were detected with the following distribution: tibia (n = 44), the clavicle (n = 34), the femur (n = 23), the fibula (n = 20) and pelvis (n = 19). The ...
