Evaluation of dual-energy CT for differentiating intracerebral hemorrhage from iodinated contrast material staining.
PURPOSE To evaluate the efficacy of dual-energy computed tomography (CT) in the differentiation of intracerebral hemorrhage (ICH) from iodinated contrast material in patients who received contrast material via intraarterial or intravenous delivery. MATERIALS AND METHODS This retrospective study was approved by the local institutional review board, which waived the informed consent requirement...
متن کاملDifferentiation of hemorrhage from iodinated contrast in different intracranial compartments using dual-energy head CT.
BACKGROUND AND PURPOSE Identification of ICH, particularly after ischemic stroke therapy, is important for guiding subsequent antithrombotic management and is often confounded by contrast staining or extravasations within intracerebral or extra-axial compartments. This study evaluates the accuracy of DECT in distinguishing ICH from iodinated contrast in patients who received contrast via IA or ...
متن کاملDual-energy CT in the evaluation of intracerebral hemorrhage of unknown origin: differentiation between tumor bleeding and pure hemorrhage.
BACKGROUND AND PURPOSE Detection of underlying tumor in patients with unknown-origin acute ICH may be difficult because acute hematoma may mask enhancement of tumor on postcontrast CT. We intended to investigate the clinical utility of DECT in differentiating tumor bleeding from pure ICH. MATERIALS AND METHODS Using a dual-source CT scanner, we obtained TNC single-energy and postcontrast DECT...
متن کاملIodinated 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...
متن کاملVirtual Non-Contrast CT Using Dual-Energy Spectral CT: Feasibility of Coronary Artery Calcium Scoring.
OBJECTIVE To evaluate the feasibility of coronary artery calcium scoring based on three virtual noncontrast-enhanced (VNC) images derived from single-source spectral dual-energy CT (DECT) as compared with true noncontrast-enhanced (TNC) images. MATERIALS AND METHODS This prospective study was conducted with the approval of our Institutional Review Board. Ninety-seven patients underwent noncon...
