RSNA preview: CT coronary angiography, CT colonography gain widespread use
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.
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.

Study: Black Patients Less Likely Than Others to Receive MRI Assessment of Cognitive Impairment
November 27th 2023In a four-year study of over 1,600 patients who had outpatient head CTs, head CT angiography and/or brain MRI to assess cognitive impairment, researchers found that Black patients were over 9 percent less likely than White patients and over 16 percent less likely than Hispanic patients to receive brain MRI.
