Dynamic bow-tie attenuation filter improves CT resolution
By Eric Barnes
Tuesday, November 27 | 10:30 a.m.-10:40 a.m. | SSG17-01 | Room S404ABIn a proof-of-concept experiment, use of a new dynamic bow-tie filter yielded lower doses and higher CT image resolution. Details of the University of Wisconsin research will be presented in this Tuesday scientific session.

128-detector-row CT permits sharp contrast dose reductions for CTPA
By Eric Barnes
Monday, November 26 | 3:10 p.m.-3:20 p.m. | SSE05-02 | Room S404CDCutting the contrast dose by two-thirds doesn't degrade image quality in CT pulmonary angiography (CTPA) acquired on a 128-detector-row scanner, say researchers from Case Medical Center and Case Western Reserve Medical School.

Myocardial disease may explain higher event rates in blacks
By Eric Barnes
Monday, November 26 | 11:40 a.m.-11:50 a.m. | SSC02-08 | Room S504ABGenerally higher myocardial measurements may explain the greater prevalence of cardiac events in blacks compared with whites, according to research from the Medical University of South Carolina, Heidelberg University, and three other centers.

Low-attenuation clusters at CT aid in quantifying emphysema in COPD patients
By Eric Barnes
Monday, November 26 | 10:30 a.m.-10:40 a.m. | SSC03-01 | Room S404ABLow-attenuating lung regions in chronic obstructive pulmonary disease (COPD) patients do correlate with the presence of emphysema and spirometric measurements, concluded researchers from Japan.

ECG-gated DSCT angiography cuts dose in atrial fibrillation patients
By Eric Barnes
Monday, November 26 | 10:30 a.m.-10: 40 a.m. | SSC01-01 | Room S405ABProspective dual-source coronary CT (DSCT) angiography can reduce radiation dose and produce high-quality images even in patients with atrial fibrillation, according to researchers from China.

CT fused with CEUS boosts enhancement before TACE
By Eric Barnes
Sunday, November 25 | 2:50 p.m.-3:00 p.m.| VSIO11-06 | Room S405ABFusing contrast-enhanced ultrasound (CEUS) with CT images improves assessment after embolization, according to research from University Medical Center Regensburg in Germany.

Contrast CT distinguishes benign from malignant adrenal masses
By Eric Barnes
Sunday, November 25 | 10:45 a.m.-10:55 a.m. | SSA09-01 | Room E351Adrenal masses are commonly seen at contrast-enhanced CT and most are benign, but when confirmation is critical, additional exams such as unenhanced CT, MR, washout CT, and PET are often ordered to make the call. But can contrast-enhanced CT do the job reliably without more tests?

Road to RSNA 2012: CT Preview
By Eric Barnes
RSNA 2012 caps an extraordinary year for CT fans who like their technology high and their radiation doses low. The CT-focused scientific sessions at this year's show explore a broad array of CT topics that are driven, more than anything, by the need to get more image information with less radiation.
