This review aims to evaluate gadoxetic acidenhanced magnetic resonance imaging in the diagnosis and staging ofcholangiocarcinoma and its different clinical and radiological classificationsproposed in the literature. We also analyze the epidemiology, risk factors incorrelation with clinical findings and laboratory data.展开更多

Cardiovascular diseases(CVDs) are the leading cause of death in the US with atherosclerosis as a significant contributor for mortality and morbidity. In this review paper, we discussed the physics of radiopacity and X-ray/CT, clinically used contrast agents,and the recent progress in the development of radiopaque imaging agents and devices for the diagnosis and treatment of CVDs. We focused on radiopaque imaging agents for atherosclerosis, radiopaque embolic agents and drug eluting beads, and other radiopaque medical devices related to catheterization procedures to treat CVDs. Common strategies of introducing radiopacity in the polymers, together with examples of their applications in imaging and medical devices, are also presented.展开更多

We provide a complete asymptotic expansion of the solution of such problems in terms of small variations in the electrical conductivity of the inclusion. Our method is based on a boundary integral perturbation theory. Our results are valid for both high and low contrast inclusions.展开更多
