Winners of an interesting new Siemens contest in CT imaging have recently been announced. The International CT Image Contest, open to clinicians that use the company’s SOMATOM Definition tomographs, was inviting submissions of low dosage scans that resulted in high quality visualizations.
Above is Portugal’s Dr. João Carlos Costa’s prize winning entry in the Dual Energy category:
Small atherosclerotic plaques in the emergence of the braquiocephalic trunk and carotid artery, which do not present a reduction of the lumen of theses vascular structures. No other changes were indentified. Using an extremely small amount of intravenous contrast, namely 35 ml, a perfect scan of the Carotid Arteries and Circle of Willis were achieved with very low dose.
The side image is Petter Quick’s winner of the Thorax category:
A 47-year-old woman with unspecific chest pain with some ST-changes of ECG but otherwise normal. CT was performed to rule out coronary artery disease, pulmonary embolism, as well as lung tumor. CT examination showed no pathology.
About the contest from a Siemens press release:
… around 300 clinical images have been submitted from more than 30 countries and were evaluated by a jury of internationally renowned professors. Here, it was possible to submit images for various body regions and from various fields of application. The winners have been announced today. They are from Belgium, China, Japan, Canada, Portugal and Sweden. The unanimous verdict of the jury: not only are the images of the winners of high quality, they convincingly show that very high diagnostic value can be achieved with an extremely low dose and that even very fine details can be displayed beyond any doubt.
Customers who use a CT scanner from the SOMATOM Definition family were able to submit clinical images in six categories, i.e. Cardiac, Vascular, Neuro, Thorax, Abdomen and Pelvis and Dual Energy, to an international jury of recognized clinical image experts.
