Low doses can make DSCT cardiac perfusion routine
April 25, 2017 -- The latest generation dual-source CT (DSCT) scanner cuts the radiation dose of cardiac CT perfusion enough to make it suitable for daily practice, according to new research. Expanded z-axis coverage and better signal-to-noise ratios can offer more information on myocardial blood flow.
Radiology in Peru: From infectious diseases to mummies
April 21, 2017 -- Imaging of tuberculosis and ancient mummies are two key areas of expertise among Peruvian radiologists, a special focus session revealed at ECR 2017. In a question-and-answer interview, Dr. Jorge Luis Guerrero Gil from Lima, Peru, outlines the main issues facing radiologists in his country.
Italian CT trial boosts lung cancer screening
April 19, 2017 -- An Italian CT lung cancer screening trial has found low-dose CT screening could reduce lung cancer and overall mortality, and it is the first European study to show results clearly in the same direction of other major lung cancer screening trials.
Ultralow-dose CT works for emphysema quantification
April 18, 2017 -- A Swiss study has shown that a CT protocol using tin filtration and iterative reconstruction reduces radiation dose levels to the equivalent of a chest x-ray for lung volumetry and also the detection and quantification of emphysema. The results nudge ultralow-dose CT ever closer to routine workup of chest pathologies.
Cardiac findings in stroke: What radiologists need to know
April 14, 2017 -- Advances in CT and MRI mean it's feasible now to identify subtle cardiac pathologies responsible for stroke that used to remain unnoticed, and this is putting greater emphasis on the know-how of radiologists, award-winning Spanish researchers believe.
4 steps to develop hybrid imaging
April 12, 2017 -- Hybrid imaging involves combining two imaging modalities, typically PET and CT, SPECT and CT, or PET and MRI. There are four steps to follow to ensure that hybrid imaging is used to its full potential, Dr. Arturo Chiti writes.
Attention focuses on added value of clinical audits
April 11, 2017 -- Compulsory clinical audits are on the horizon. Skeptics fear they are time-consuming and costly, interrupting daily practice and resulting in stressful and hurried activity followed by a gradual slackening in standards once the audit is over. But a Belgian group thinks otherwise.
Spanish present 15-point plan to reduce error rates
April 5, 2017 -- A group of experienced radiologists from Madrid has developed a comprehensive, practical approach to cut error rates by adopting methods such as standardized imaging protocols. They collected a certificate of merit at ECR 2017 in Vienna for their efforts.
Two CCTA techniques cut iodine dose across vendors
March 27, 2017 -- Major contrast reductions in coronary CT angiography (CCTA) can be achieved across vendor platforms with a couple of simple techniques, according to a Dutch presentation at this month's ECR 2017 in Vienna.
Monitoring software enables pediatric dose reduction
March 15, 2017 -- The combination of dose monitoring software and continuing education for radiographers/technologists can produce quantifiable reductions in radiation dose delivered to pediatric patients from conventional radiography studies, according to research presented at ECR 2017 in Vienna.
