Introduction Hypersensitivity reactions to iodinated radio contrast media (RCM) are either immediate-type (IT) or delayed reactions (DT). In IT, the patho... K Scherer,T Harr,S Bach,... - 《Clinical & Experimental Allergy Journal of the British Society for Allergy & Clinical Immunology》 被...
The dominant producers of iodine today are Chile and Japan. Due to its high atomic number and ease of attachment to organic compounds, it has also found favour as a non-toxic radiocontrast material. Because of the specificity of its uptake by the human body, radioactive isotopes of iodine c...
Issues of contrast allergy and contrast-inducednephropathyrelate more to theiodinated compoundsadministered in CT than to other contrast agents used in diagnostic imaging. It is important to consider these issues when ordering a CT examination and to discuss the indications and risks with the radiologis...
heavy element, is quite radio-opaque. Organic compounds of a certain type (typically iodine-substituted benzene derivatives) are thus used in medicine as X-ray radiocontrast agents for intravenous injection. This is often in conjunction with advanced X-ray techniques such as angiography and CT ...
(white arrow). It is difficult to differentiate tumors from stool. (C) Dual-energy contrast-enhanced CT (axial plane) revealed no enhancement of masses, iodine value = −1.4 mg/ml (white arrow), suggesting no blood supply to the masses, which was validated as stool by colonography...
This prospective, single-institution study was approved by the Institutional Review Board, and written informed consent was provided by each patient. From December 2015 to June 2019, 317 consecutive patients received tri-phase abdominal CTA. Patients with iodine contrast media allergy, known renal dysf...
