title: [Arterial DSA in malignant hypervascularized bone tumors].
abstract: In order to evaluate intra-arterial DSA in malignant bone tumors (osteosarcoma n = 2, aggressive osteoblastoma n = 1) three patients were examined angiographically including conventional arteriography and DSA. Compared with conventional angiograms DSA imaging demonstrated a reduced peripheral vascular information due to reduced spatial resolution. Advantages of DSA were an improved visualization of tumor blush and atypical venous return and in addition a reduction of volume rsp. concentration of the contrast material using a iodine concentration of 200 mg/ml for preoperative vascular mapping and of 300 mg/ml for diagnostic tumor imaging.
