title: Three-dimensional MRI reconstructions of musculoskeletal tumors. A preliminary evaluation of 2 cases.
abstract: We have developed a new method for three-dimensional (3D) reconstruction of malignant bone and soft-tissue tumors from MRI. Data from transverse images of T2-weighted images were transferred into a personal computer. The contours of tumors, major vessels, major nerves and bones were outlined, whereupon the 3D data were processed into a 3D display, using a solid model. The determination of tumor volume both before and after preoperative adjuvant therapy was quantified. The 3D images allowed a better understanding of the relationship between the tumor and the major vessels and nerves, thereby aiding in preoperative planning. The images also provided a quantitative, reproducible measurement of the effect of adjuvant therapy.
