Objective: This retro-prospective study was performed to evaluate the diagnostic accuracy of various imaging modalities as compared to histopathological findings in tumours and tumour-like lesions of bone. Materials and Methods: Imaging findings of 70 patients in the age group of 2 to 75 years were evaluated. The findings on Radiographs, Computed Tomography (CT), and Magnetic Resonance Imaging (MRI) were correlated with histopathological findings. Results: 70% of the bone lesions were benign on histopathology and 30% were malignant. Plain radiographs showed a sensitivity of 80.95%, and 95.92% specificity, with a PPV of 89.47%. NPV of 92.16%, and diagnostic accuracy of 91.43% were seen. CT showed a sensitivity of 95.0%, specificity of 91.67%, PPV of 86.36%, NPV of 97.06%, and diagnostic accuracy of 92.86%. On MRI 100% sensitivity, 93.8% specificity, a PPV of 91.3%, a NPV of 100%, and diagnostic accuracy of 96.23% were found. On comparing findings on radiographs, CT, and MRI with histopathological findings, ... : Objective: This retro-prospective study was performed to evaluate the diagnostic accuracy of various imaging modalities as compared to histopathological findings in tumours and tumour-like lesions of bone.
