[Can magnetic resonance imaging differentiate between benign and malignant conditions in patients with skeletal or soft tissue tumors?].
The records of 437 patients referred preoperatively for magnetic resonance imaging (MRI) due to clinical or radiological suspicion of a bone or soft-tissue malignancy were examined retrospectively in order to evaluate how good MRI is at distinguishing malignant from benign lesions. The MR-examination tends to overestimate malignancy. In all cases, the preoperative MR-examination correctly identified all malignant tumours as malignant, but also estimated a number of benign lesions as malignant. Sensitivity, specificity and predictive value was 100%, 71.2% and 76.4% respectively. In case of bursa/ganglion and pseudotumour, MR was able to correctly identify these lesions as benign. MR could not differentiate between the different types of sarcomas.
