  • Title: [Arterial DSA in malignant hypervascularized bone tumors].
    Author: Arlart IP, Merk J, Bähren W.
    Journal: Rofo; 1984 Nov; 141(5):541-4. PubMed ID: 6438719.
    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.
