January 3, 2012 – Siemens Healthcare recently announced the winners of its 2011 International CT [computed tomography] Image Contest. More than 160 institutes and hospitals from 43 countries on all continents submitted more than 600 CT images –– all captured on Siemens CT scanners using the lowest possible radiation dose. Selected by an international jury of experts, the seven winners –– which were displayed at RSNA 2011 –– hail from China, England, France, Ireland, Macau, Singapore and the United States. In addition to exhibiting a high standard of quality, the images are impressive examples of how valuable diagnostic information can be obtained even at an extremely low dose.
For this second annual contest, Siemens customers with a Somatom Definition, Somatom Emotion, Somatom Sensation or Somatom Spirit CT scanner were invited to present clinical images in seven medical categories to an international jury of recognized experts.
From March through September, a fan community of more than 4,000 members discussed the submitted CT images on Facebook. Additionally, all Internet users could vote for their favorite image in a public vote. In eight months, the contest’s Internet page received 40,000 hits, raising public awareness of the responsibility that manufacturers and radiologists have regarding diagnostic radiation.
