Iodinated Contrast Media and Cerebral Hemorrhage After Intravenous Thrombolysis

Background and Purpose—Iodinated contrast is increasingly used in CT perfusion or angiographic examinations in acute stroke. Increased risk of intracranial hemorrhage (ICH) complicating microcatheter contrast injections has recently been reported in the second Interventional Management of Stroke (IMS 2) trial with contrast toxicity potentially contributory. Methods—We reviewed clinical and radi...

The effect of CT contrast agents on treatment planning and dose calculation in radiation therapy of pelvis cancers

Introduction: Using contrast medium in diagnosis and identifying of an organ from its surrounding tissue is very useful. These contrast mediums alter radiation absorption of studied organs. The aim of this study is to identify the influences of contrast media in treatment planning system of the pelvis.   Materials and Methods: Seven patients with pelvis area ...
