Noncathartic CTC prep might boost screening compliance
By Eric Barnes
The use of noncathartic bowel preparation before CT colonography (CTC) delivers good sensitivity for clinically significant polyps, and may also increase colorectal cancer screening compliance, according to a report in the American Journal of Roentgenology.

FDG-PET/CT tops MRI in colon cancer staging
By Wayne Forrest
Wednesday, December 4 | 3:00 p.m.-3:10 p.m. | SSM17-01 | Room S505ABWhile whole-body MRI is a feasible method for staging colon cancer patients, the modality does not quite reach the accuracy of FDG-PET/CT, according to a new study by Italian researchers.

PET/MRI, PET/CT both beneficial for primary pelvic tumors
By Wayne Forrest
Wednesday, December 4 | 11:40 a.m.-11:50 a.m. | SSK09-08 | Room N228In this scientific session, researchers from University Hospital Zurich will present the clinical benefits from both PET/MRI and PET/CT for evaluating primary tumors in the pelvic region.

FDG-PET/CT perhaps unnecessary for anal cancer staging
By Wayne Forrest
Monday, December 2 | 3:40 p.m.-3:50 p.m. | SSE08-05 | Room E353CIn this scientific session, Swedish researchers will discuss how contrast-enhanced CT appears to be sufficient for lymph node staging in squamous cell carcinoma of the anorectum and anal verge, decreasing the need for biopsy and PET/CT.

Iterative reconstruction permits sub-mSv CT colonography
By Eric Barnes
Wednesday, December 4 | 11:20 a.m.-11:30 a.m. | SSK05-06 | Room E351Researchers dialed their CT radiation dose way down -- to 1 mSv per CT colonography exam -- and reconstructed the images using two different iterative reconstruction algorithms in this study from Korea.

Costs remain low in workup of extracolonic findings
By Eric Barnes
Wednesday, December 4 | 10:30 a.m.-10:40 a.m. | SSK05-01 | Room E351In this scientific session, Italian investigators will discuss their conclusion that it's not expensive to work up patients with potentially serious extracolonic findings, especially considering the benefits of finding serious conditions early.

Absorbed dose varies between single-, dual-source CT colonography
By Eric Barnes
Sunday, December 1 | 12:30-1:00 p.m. | LL-PHE3075-SUA | Lakeside Learning CenterThe dose readout on your scanner doesn't really tell you much, according to a group from Massachusetts General Hospital, who looked into dose differences between different scanners and scan modes for this education exhibit.

Ultrasound can help identify appendicitis in borderline cases
By Kate Madden Yee
Thursday, December 5 | 10:30 a.m.-10:40 a.m. | SSQ05-01 | Room N226Ultrasound reliably predicts appendicitis if secondary characteristics are assessed when the appendix is of borderline size, defined as 6 mm to 7 mm in diameter, according to a study to be presented in this Thursday RSNA 2013 session.
