All about contrast media
An extensive survey of contrast media for X-ray and MRI examinations describes the agents’ mechanisms of action and highlights the recent research activities in the area.

Quantitative differentiation during hepatocarcinogenesis
An international study compared the signal intensities of hepatospecific contrast enhancement in dysplastic nodules and hepatocellular carcinomas at different stages. The contrast agent Gd-EOB-DTPA might serve as a useful marker for differentiation.

Effective doses in neonate and infant cardiac catheterization
A Japanese study reveals data on absorbed radiation doses based on in-phantom dosimetry.
Baker ME et al. (biho/ktg)
Scout images serve for radiation dose estimation in CT
Estimated CT scanner radiation output based on scan-generated topograms is quite close to the actual dose index. Simulated protocols show that automated kilovoltage protocols (kVp) are able to decrease radiation dose even further.
Kost SD et al. (biho/ktg)
Pediatric CT: Coming closer to accurate patient doses
Predicting radiation doses as precisely as possible helps keeping radiation dose as low as possible. A well-thought-out simulation model estimates radiation doses in the most radiosensitive patient group prior to the scan.

The benefit of blogs
An international study assessed the value of blog posts as disseminating media for radiological research. Radiologists might profit from this social media tool.

Is online as good as a live lecture for radiologic staff training?
Continuous training of radiology staff is necessary to guarantee patients’ safety and to get the most out of imaging examinations. Online tools turn out to be as good as live lectures.

The effects of lower tube voltage in coronary computed tomography angiography
Radiation dose reduction can be obtained by lowering the tube voltage in coronary computed tomography angiography. The image quality is not affected.

It’s up to you: Social media and radiologists’ perception
Radiologists can only profit from social media. Use of facebook, twitter and others enlarge their visibility and underline their importance for medical health care.

Background parenchymal enhancement as biomarker in breast cancer
MRI-derived information on surrounding parenchymal tissue enables the distinction of healthy and cancerous breast tissue.
Leng S et al. (biho/ktg)
Dose reduction for the inner ear
A state-of-the-art CT protocol with iterative image reconstruction (IR) helps to significantly reduce radiation output in temporal bone CT scans.

Talking about radiation risks in medical imaging
Radiologists from leading US-American universities underline that patients must be informed about radiation-related risks. This review reveals that information policy needs to be improved.

HCC and benign lesions in the non-cirrhotic liver
A Swiss study reveals four independent predictors for HCC diagnosis and differentiation from benign lesions in the non-cirrhotic liver.
Matoori S et al. (biho/ktg)
The role of age in contrast enhancement
Swiss study results point to the important link between patient age and relative signal enhancement ratios of gadoxetic acid-enhanced liver MRI. However, uptake and depletion of the contrast agent seem not to be influenced by age.

Radiologists in a mass-casualty situation
The US-American Armed Forces Radiobiology Research Institute reminds radiologists of their duty in case of a radiation incident. Radiologists should be well prepared to take care of the casualties.
