RESUMO
Background: A bone tumor is a neoplastic growth of tissue in bone. Abnormal growths found in the bone can be either benign (noncancerous) or malignant (cancerous). Aims and objectives: The purpose of this study was to evaluate the role of MRI in cases of primary malignant bone tumors and MRI characteristics of different primary malignant bone tumors, to compare the imaging findings with surgical and gross pathological findings, Staging of tumor on MRI, correlating them with operative and histopathological findings. Materials and methods: This was a prospective study done in Department of Radiodiagnosis of NRIGH comprising of 40 patients 21 male and 19 female who were suspected or proven cases of the malignant bone tumor. Plain radiographs in AP and Lateral views (including the adjacent joint) were taken in all cases. The primary pulse sequences included T1 and T2 WI using spine echo and gradient echo techniques with TR of 600 msec. and TE 30msec. for T1WI and TR of 2740 msec. and TE of 85 msec. for T2 WI . The MR morphology was correlated with surgical and histopathological features. Results: The study “Multiplanar MR Imaging of primary malignant bone tumors with surgical and histopathological correlation” comprised of 40 patients in a two year period starting from august 2010 to September 2012 the age ranged from 8 years to 71 years (mean 40 years). There were 21 males and 19 females. Conclusion: MRI in combination with plain radiography is an excellent modality for evaluation of the musculoskeletal pathologies especially differentiating a malignant from a benign lesion. The multiplanar imaging capabilities place a major role in delineation of tumour extent in to the bone and Karuna V, R Vikash Babu.
