Purpose In 2023, the American College of Radiology (ACR) Committee on Bone-RADS has published a scoring system based on radiographic features of bone lesions, to assign a numerical score that aids in predicting the risk of malignancy, with appropriate recommendations for patient management (table 1 and 2) [1-3].Conventional radiography still plays a key role in the initial evaluation of bone lesion, allowing to detect it, to identify its matrix and features of aggressiveness [4].Since the ACR Bone-RADS is the first radiographical score...
Read more Methods and materials Study populationPatients with histologically proven bone lesion of the extremities were retrospectively enrolled. The reference standard was post-surgical pathology for surgically-treated lesions and biopsy for non-operated lesions.All biopsies and surgical procedures were performed between January 2015 and December 2022 in a tertiary bone sarcoma center.All included patients had undergone a radiograph of the involved bone segment within three months prior to biopsy or surgery.Radiologists' evaluationAll x-rays were reviewed following the ACR Bone-RADS score by three radiologists with different experience in...
Read more Results The final cohort consisted of 285 patients (150 males, 135 females) with a mean age of 49.0 years (SD 21.0; range 8-92).The most frequent histological diagnosis of the bone lesions was metastasis (72/285, 25.3%) followed by atypical cartilaginous tumor (ACT)/chondrosarcoma grade I (54/285, 18.9%) - (Table 3).Interobserver agreement (Table 4 - Figure 1)The two musculoskeletal Radiologists (Readers 1 and 2) showed at least substantial agreement for all the Bone-RADS categories (Kappa values ranging from 0.84 to 0.99).The highest agreement was...
Read more Conclusion Our results demonstrated that the ACR Bone-RADS has a high reproducibility, with a substantial interobserver agreement on almost all the assessment categories of the score, even among radiologists with different experience in bone tumor imaging.The score revealed a high accuracy in the identification of benign lesions; however, it can underestimate the risk in cases of cartilaginous tumors. Therefore, we recommend incorporating lesion size into the decision-making process and considering additional imaging instead of follow-up for a chondroid lesion with Bone-RADS...
