| Abstract: | In a clinical study of 13 patients, gadolinium-DTPA (Gd-DTPA) was used for enhancement of soft tissue tumors at magnetic resonance imaging. Gd-enhanced T1 sequences were found to give additional information concerning tumor vascularity in 11 cases, tumor necrosis in 2 cases and tumor delineation in one case, compared with conventional T1 and T2 weighted spin echo sequences. If Gd-enhanced sequences were to be used as the only source of information, accurate assessment of tissue composition of the tumor would not have been possible. Furthermore, valuable information regarding tumor delineation towards surrounding fat may be lost. |
