Abstract
Summary and conclusion
Musculoskeletal tumors are a rare and diverse group. Benign bone and soft tissue tumors are 100 times more common than malignant tumors. As the survival of patients with carcinomas is gradually extending, presentation with bone metastases will also rise.
The imaging evaluation of musculoskeletal tumors involves a multimodality approach. Each modality provides different diagnostic information.
DW imaging is a non-enhanced functional MR imaging technique that is easily incorporated into a routine MR imaging protocol with little addi¬tional scanning time and that offers useful infor¬mation regarding the cellularity of a musculoskel¬etal lesion.
The use of whole-body DW imaging for the purpose of tumor detection has been studied, and localized DW imaging is a promising technique for characterizing lesions and assessing treatment response.
DWI can differentiate benign and malignant lesions of non- myxoid soft tissue tumors thus decreasing the need for unnecessary biopsy. It can also asses treatment response for both osseous and soft tissue tumors.
Further investigation is still needed to identify the influence of DW imaging– ADC mapping on management and outcome in patients with musculoskeletal lesions.
