Utility of Magnetic Resonance Imaging in the Assessment of Primary Bone Tumors

Abstract

Background: These radiographic features, coupled with clinical information, help to define whether the lesion is neoplastic or non-neoplastic, primary or metastatic, and will help to direct the subsequent work-up further. MRI is the best modality to assess the focal extent and local staging. Aims and Objectives: To assess the Utility of magnetic resonance imaging in assessing primary bone tumors. Materials and Methods: Present cross-sectional study was performed on 50 patients undergoing magnetic resonance imaging with clinical suspicion of primary bone tumors at the Department of Radiodiagnosis. A detailed socio-demographic, in addition to routine MR pulse sequences, was recorded. Results: In our study, 31 cases (62 %) had a wide zone of transition, in which 25 cases were benign, and the remaining 6 cases were malignant, while 19 cases (38 %) had an arrow zone of transition and all 19 cases (38%) were malignant. This difference was found to be statistically significant. (χ2 value = 30.645 , p value= 0.0001. Sixteen patients (32%) were in the age group of 11-20 years of age. The majority of the primary bone tumors (72%) were observed in the appendicular skeleton; the most commonly involved bones were the femur, tibia, and humerus in 19, 8, and 5 cases, respectively. Conclusion: MR imaging is an excellent modality to delineate the extent of the tumor, and soft tissue involvement, localize the lesion, and determine its aggressiveness. The findings of this population study are consistent with other studies in this field. So we have sufficient evidence to conclude that MRI is highly accurate in diagnosing bone tumors.
