Abstract: 【Abstract】〓Objective〓To investigate the relationship between iodinated contrast agent in different temperatures with incidence of adverse drug reactions (ADR) after CT angiography. Methods 3200 testers who examined with multi detector CT angiography were randomly divided into two groups, normal temperature group(n=1520) and heating group(n=1680), which performed CT angiography with contrast agent of home temperature and heated to 37 in the constant temperature box..The incidence of exosmose and anaphylactoid reaction after contrast agent injection were detected. Results〓The incidence of exosmose and anaphylactoid reaction in heating group was lower than that of normal temperature group after iopromide intravenous injection..Conclusion〓It is worthy of being widely popularized in clinical application with heating of iodinated contrast agent which may reduce the incidence of ADR.
