Side Effects of Radiographic Contrast Media
Radiographic contrast agents have been in use for over 60 years to improve the visibility of internal organs and structures in X-ray based imaging techniques such as radiography, angiography, and contrast-enhanced computed tomography scans and to perform cardiac catheterizations and percu-taneous coronary interventions. Their use for imaging and intravascular intervention keeps increasing parti...
متن کاملPlatelet and fibrin modification by radiographic contrast media.
The effect of the radiographic contrast agents, iopamidol and diatrizoate, on fibrin assembly and structure as well as platelet surface charge was studied. Increasing the iopamidol concentration from 0 to 4.5 mM prolongs the fibrin gelation time from 20 to 105 seconds (an anticoagulant effect) and reduces the fibrin fiber mass/length ratio from 3.2 x 10(12) to 0.5 x 10(12) Da/cm (i.e., produces...
متن کاملAcute Kidney Injury by Radiographic Contrast Media: Pathogenesis and Prevention
It is well known that iodinated radiographic contrast media may cause kidney dysfunction, particularly in patients with preexisting renal impairment associated with diabetes. This dysfunction, when severe, will cause acute renal failure (ARF). We may define contrast-induced Acute Kidney Injury (AKI) as ARF occurring within 24-72 hrs after the intravascular injection of iodinated radiographic co...
متن کاملImmunologic basis for adverse reactions to radiographic contrast media.
The lymphocyte transformation test (LTT) was used to elucidate whether certain side effects induced by radiographic contrast media have an immunologic etiology. Groups studied were: 8 patients who had previously experienced adverse reactions in association with urography, 6 patients who underwent urography without notable side reactions, 17 occupationally exposed nurses, and 9 unexposed control...
متن کاملIntravascular radiographic contrast media: issues for family physicians.
BACKGROUND Family physicians frequently order and in some instances supervise diagnostic tests using intravascular radiographic contrast media. METHODS MEDLINE database was searched from 1966 to the present using the key terms "contrast media," "adverse reaction," "anaphylaxis," "anaphylactoid," "nephropathy," "renal failure," "kidney failure," and "MRI" in combinations. Other sources were fo...
