Contrast agent choice for intravenous coronary angiography

Triphasic Contrast Agent Injection in 64-MDCT Coronary Artery Angiography

Purpose: To evaluate image quality and cardiovascular enhancement after triphasic injection in 64-slice-CT coronary angiography (c-CTA). Methods: c-CTA of twenty-two asymptomatic patients following triphasic injection (65ml-contrast bolus + mixed 30mlcontrast and 20ml-saline bolus + 50ml-saline chaser) were retrospectively reviewed. Attenuation in the great vessels, cardiac chambers, and corona...

Successful rapid intravenous desensitization for radioiodine contrast allergy in a patient requiring urgent coronary angiography.

An 81-year-old white woman presented to our hospital with chest pain on a background history of recurrent left main coronary artery in-stent restenosis and severe allergic reaction to iodixanol (Visipaque; GE Healthcare, Mississauga, Ontario, Canada) radiocontrast media (RCM). The patient’s cardiovascular risk factors included only dyslipidemia. The patient’s cardiac history was significant for...

The Impact of Warmed Intravenous Contrast Material on the Bolus Geometry of Coronary CT Angiography Applications

OBJECTIVE This study was designed to investigate the effect of administration of warmed contrast material (CM) on the bolus geometry and enhancement as depicted on coronary CT angiography. MATERIALS AND METHODS A total of 64 patients (42 men, 22 women; mean age, 56 years) were randomly divided into two groups. Group 1 included 32 patients administered CM (Omnipaque [Iohexol] 350 mg I/ mL; Nyc...

Coronary Angiography and Contrast-Induced Nephropathy

atorvastatin and prevention of contrast induced nephropathy following coronary angiography

background: contrast induced nephropathy (cin) is one of the most common complications after radiographic procedures using intravascular radiocontrast media. the aim of the current study was to assess the effect of atorvastatin on prevention of cin in patients undergoing coronary angiography. materials and methods: in a clinical trial study, 200 patients referred for angiography were randomly d...
