The purpose of this article is to prospectively assess the frequency and type of IV injection site complications associated with high-flow power injection of nonionic contrast medium in MDCT. Read more

At sub-second, low radiation dose CTA of the chest, use of individualized, patient-based contrast media delivery protocols results in reliable, diagnostic contrast enhancement of all target vessels. Read more

Purpose To investigate the impact of right ventricle (RV) contrast attenuation on the accuracy of RV function analysis at cardiac CT performed for coronary imaging. Materials and methods We analyzed multi-phase cardiac dual-source CT studies of 40 consecutive patients (mean age 60.9+/-12.3 years; 13 women) with normal valve function. Function analyses of … Read more

Judy Oltman, USA, has sent the following question: We do a fair amount of pediatric congenital hearts and need to assess right ventricular function. Are there any particular blends of contrast administration that works well with attemping to get appropriate contrast fill without too much contamination? Kai U. Juergens, M.D., Section Head … Read more

Judy Oltman, USA, has sent the following question: Contrast blending for right ventricular function: We do a fair amount of pediatric congenital hearts and need to assess right ventricular function. Are there any particular blends of contrast administration that works well with attemping to get appropriate contrast fill without too much contamination? Thorsten … Read more

Purpose To achieve a desired level of enhancement with the least amount of contrast media (CM) at dual-source CT (DSCT) coronary angiography by using a computerized algorithm for patient-specific adaptation of CM volume and injection parameters. Method and materials In 32 patients undergoing CM (300 mgI/ml) enhanced coronary DSCT we used a computerized … Read more
