From the annual meeting of the Radiological Society of North America
Attendees at this year’s annual RSNA meeting were met with an expanded layout of technical exhibits that for the first time spanned three halls of Chicago’s cavernous McCormick Place convention center. But the buzz heard round the mighty McCormick on opening day was sparked before the meeting ever started with the release of the multicenter, prospective CorE-64 study.
In an article published in the Nov. 27 issue of the New England Journal of Medicine, investigators at Johns Hopkins University concluded that 64-row multidetector CT angiography isn’t accurate enough – given a positive predictive value of 91% and negative predictive value of 83% – to replace conventional coronary angiography in patients with suspected symptomatic coronary artery disease.
An accompanying editorial observed that the use of cardiac imaging has been increasing by 26% per year, despite a lack of evidence of outcome benefit. “Without such evidence, a high-resolution cardiac CT angiographic image of the heart is just another pretty picture,” the editorialists wrote.
Ouch!! You could almost hear the groans emanating from the booth run by Toshiba, which helped sponsor the CorE-64 study and is showcasing its new 320-detector row CT scanner at this year’s RSNA meeting.
