Hexabrix--a new contrast medium in angiocardiography.

The hyperosmolality of current ionic angiographic media gives rise to several adverse effects. Use of the first low-osmolality medium, metrizamide (Amipaque), has been inhibited by expense and by the necessity for prior mixing into solution. Hexabrix is the first of such media to be available in stable solution, and its use in angiocardiography is reported, in direct comparison with Urografin, ...

The physiologic effect of contrast media used for angiocardiography.

The deaths from angiocardiography at Wisconsin General Hospital were reviewed and found to be two per cent of 249 patients. These 5 deaths are reported briefly. Investigation was carried out to determine the hemodynamic effects of contrast substances on 12 dogs. In general, there was a temporary increase in right atrial and pulmonary arterial pressure followed by a rather marked decrease in sys...

Contrast Agents

MRI has become a very important tool for clinical diagnosis of disease as well as in biomedical studies for the noninvasive three-dimensional imaging of living subjects and specimens. It can distinguish between various parts of soft tissue water based on differences in the longitudinal relaxation time (T1), the transverse relaxation time (T2), the apparent transverse relaxation time (T2*) and t...

Impact of contrast agents on dose algorıthms of planning systems

Background: Use of contrast agents (CAs) during CT simulation for treatment planing system leads to changes in  electron density. In this study we aimed to investigate the effect on  calculated dose of various concentrations of CAs on treatment planing systems in different dose calculation algorithms. Materials and Methods: Contrast agent (0.769 mg/ml Iopromid) - water mixtures at con...
