Preliminary numbers released by the Radiological Society of North America show that attendance was similar to last year's numbers. By Thursday, Dec. 6, the number of total attendees was 53,169, only 196 less than it had been by the final day of the meeting in 2012.
Professional attendance was up 1% to 26,572 by the final day of the meeting this year, while guest attendance was down 2% to 5,279 and exhibitor attendance was flat at 21,318.
Meeting attendance had spiked in 2011 when it reached 59,097, almost two percent higher than in 2010, according to an RSNA press release. Other notable figures that year included non-exhibitor attendees at 36,671, international professionals at 9,642, RSNA member residents at 3,624 (13% more than in 2010), and medical physicists at 1,328 (nearly 17% more than in 2010).
However, 2011 was also the year RSNA launched its virtual meeting offering making it possible to hear many meeting presentations and earn CME without traveling to Chicago. It remains one of the largest conferences in the world, with an estimated $130 million economic impact to the City of Chicago.
