Aorto-Peripheral MDCT Angiography: Implications for Contrast Medium Delivery

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...

Dual Energy CT Angiography of Peripheral Arterial Disease: Feasibility of Using Lower Contrast Medium Volume

OBJECTIVE One of the main drawbacks associated with Dual Energy Computed Tomography Angiography (DECTA) is the risk of developing contrast medium-induced nephropathy (CIN). The aim of the present study was firstly, to design an optimal CT imaging protocol by determining the feasibility of using a reduced contrast medium volume in peripheral arterial DECTA, and secondly, to compare the results w...

Contrast Medium Delivery Strategies and Radiation Dose Parameters Affecting Renal CT Angiography: Literature Review

Contrast peripheral phlebography and pulmonary angiography for diagnosis of thromboembolism.

At one time, direct intravascular contrast angiography was the standard method for confirmatory diagnosis of venous or pulmonary arterial thromboembolism. Although sensitive and specific, conventional catheter-based contrast imaging is invasive and associated with a risk of phlebitis and thrombosis. These procedures require specialized training and experience in catheter manipulation, as well a...
