Malignant extradural spinal tumors: MR imaging with Gd-DTPA.

摘要: Magnetic resonance (MR) imaging with gadolinium diethylenetriaminepentaacetic acid (DTPA) was performed in 12 patients neoplasia of the spine and epidural space. Postcontrast images were compared precontrast images. Gd-DTPA MR did not improve detection tumors affecting space spine. In fact, many lesions isointense when intensity surrounding bone marrow difficult to see. Because this, contrast material-enhanced sufficient; however, they combined images, use improved delineation characterization certain lesions. helpful differentiating disk herniation from tumors, indicating regions more active tumor for biopsy, outlining areas spinal cord compression, demonstrating response therapy. Therefore, while it may be unlikely that will used routinely every case suspected epid...
