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?

DSCT compares full- to half-dose VC by patient
By Eric Barnes
Mayo Clinic researchers used iterative reconstruction to acquire half-dose virtual colonoscopy exams with dual-source CT (DSCT) and compare them to full-dose exams without scanning patients twice. The technique offers a more accurate way to compare dose levels between different CT protocols, according to a new study in the Journal of Computer Assisted Tomography.

2 technologists read VC studies as well as 1 radiologist
By Eric Barnes
When it comes to reading virtual colonoscopy studies, a radiologic technologist is no match for a trained radiologist. But two technologists are another matter entirely: They were equivalent to, and maybe slightly better than, a single radiologist, according to a new study in Radiology.
