摘要：

The accuracy of preoperative MRI in detecting tumor extent has been evaluated in 35 patients with primary bone neoplasms; intra-osseous extent was measured on MR images and compared with macroslides of surgical specimens in 26 cases. An almost completely accurate prediction of tumor size was obtained with the combined employment of Spin-Echo (SE) and Short Inversion Time Inversion Recovery (STIR) sequences in the various tumors, with the exception of two Ewing's sarcomas. Changes in Signal Intensity (SI) and tumor morphology were identified in those cases which had undergone presurgical chemotherapy: the reduction in SI and in tumor size or the appearance of a more homogeneous signal was correlated with a positive response to cytotoxic therapy. MR imaging fully satisfies surgeon's preoperative requirements in the assessment of therapy-responding neoplasms as well as in local tumor staging in all types of neoplasms, with the exception of Ewing's sarcoma.
