Highlights of the 2008 RSNA meeting include discussions about the use of CT angiography as a noninvasive technique for diagnosing coronary artery disease and the replacement of standard optical colonoscopy with CT colonography to screen for colon cancer.
Coronary CTA is a hot topic, said Dr. David Levin, professor emeritus of radiology at Thomas Jefferson University Hospital.
"It has high impact and a lot of ramifications for a lot of patients, because it's a way to diagnose coronary artery disease noninvasively," Levin said.
The technique has been used for the last five years, but it has become more widely used with the development of 64-slice CT scanners in academic and large community hospitals, as well as in many physicians' offices.
"It's a good diagnostic test," Levin said.
He cited as another topic of interest a relatively new procedure: CT colonography.
"There's a lot of interest in using it for screening colon cancer," Levin said.
Some disagreement persists, however, between radiologists and gastroenterologists about using CT colonography or the more common standard optical colonoscopy.
In the Health Services Policy and Research areas, notable topics will include the disparity in types of imaging related to socioeconomic status or insurance coverage, the effects of including a patient photo with a radiologic exam, occupational stress in radiologists, and evaluation of an outpatient imaging center where radiologists consult directly with patients, said subcommittee chair Dr. Ruth C. Carlos.
Other presentations this year will address resident education, evidence-based medicine, and guideline development.
Among the notable scientific papers to be introduced at the upcoming meeting in Chicago are the following:
Can Polyenergetic Reconstruction Help Resolve Streak Artifacts in Photon Counting CT?
July 22nd 2024New research looking at photon-counting computed tomography (PCCT) demonstrated significantly reduced variation and tracheal air density attenuation with polyenergetic reconstruction in contrast to monoenergetic reconstruction on chest CT.
Systematic Review: PET/MRI May be More Advantageous than PET/CT in Cancer Imaging
July 18th 2024While PET/MRI and PET/CT had comparable sensitivity for patient-level regional nodal metastases and lesion-level recurrence, the authors of a systematic review noted that PET/MRI had significantly higher accuracy in breast cancer and colorectal cancer staging.
The Reading Room: Artificial Intelligence: What RSNA 2020 Offered, and What 2021 Could Bring
December 5th 2020Nina Kottler, M.D., chief medical officer of AI at Radiology Partners, discusses, during RSNA 2020, what new developments the annual meeting provided about these technologies, sessions to access, and what to expect in the coming year.
FDA Clears Enhanced Mobile CT System with High-Resolution Photon-Counting Technology
July 15th 2024Photon-counting CT-optimized features with the OmniTom Elite system include 30 cm field of view scanning, continuous spiral scanning, and an ultra-high-resolution capability of 0.141 mm resolution.
