Background Radiographs are the most valuable modality for diagnosis of bone tumors, however MRI is emerging as the modality of choice for assessing local spread of tumor. Objective To assess role of MRI in local spread of tumor and comparison to surgical & histo-pathological results. Results 47 patients ( age 10-73 years with mean age of 38 years) were studied from May 2018 to November 2019. There were 26 males and 21 females, 9 patients were excluded as no operative results were available. Out of the 38 total cases, 11 were osteosarcoma, 7 were Ewing’s sarcoma, 7 were GCT, 6 were Chondrosarcoma, 2 Osteochondroma, 1 PNET, 1 ABC, 1 Hemangioma, 1 Chordoma and 1 Multiple myeloma. Cortical break was detected in 29 patients on MRI with 2 false positive cases showing 93% accuracy. Medulla involvement was detected in 34/35 patients (97%). Neuro-vascular involvement was detected in 9 patients on MRI with 1 false positive cases showing 88.9% accuracy. Joint involvement was detected in 13 patients on MRI with 2 false positive cases showing 84.6% accuracy. All 4 cases of skip lesion (100%) were detected on MRI. Conclusion MRI is the modality of choice to assess for local spread of bone tumors.
