Mannitol in water outperforms iodinated oral contrast
Thursday, December 3 | 11:00 a.m.-11:10 a.m. | SSQ08-04 | Room E353CThe use of mannitol as an endoluminal contrast agent increases diagnostic efficacy in bowel pathology, handily beating iodinated contrast and water alone, according to research from Kasturba Medical College in Manipal, India.

Perfusion CT improves distinction of benign versus malignant lymph nodes
Thursday, December 3 | 10:30 a.m.-10:40 a.m. | SSQ13-01 | Room N228Perfusion CT offers additional functional information for the characterization of lymph nodes, which is useful for distinguishing benign from malignant nodes, according to a research team from India with extensive experience in perfusion imaging.

High-pitch DECT unfazed by squirming kids
Wednesday, December 2 | 3:10 p.m.-3:20 p.m. | SSM19-02 | Room N230Judging from the results of a phantom study using dual-energy CT (DECT), infants will soon be able to squirm and fuss all they want without blurring the images. Lead author Cynthia McCollough, Ph.D., told AuntMinnie.com there's a lot of excitement around the use of high-pitch scanning in children to facilitate the whole process.

Few CIN cases among at-risk contrast-enhanced CT patients
Wednesday, December 2 | 11:30 a.m.-11:40 a.m. | SSK11-07 | Room S102DThe Netherlands guidelines issued in 2007 for administering iodine-based contrast media recommend determining renal function before contrast-enhanced CT in patients 60 years and older with diabetes mellitus, heart failure, vascular disease, hypertension, history of renal disease, or urologic disease. Radboud University Nijmegen Medical Center researchers sought to update the guidelines with the assessment of their CT population of 319 consecutive patients scanned over two weeks.

Patient history, indications can inform which incidental lung nodules to work up
Wednesday, December 2 | 11:30 a.m.-11:40 a.m. | SSK06-07 | Room S504CDRadiologists often run into incidental lung nodules when performing abdominal CT, but it's not always clear whether to work them up. To help address this issue, Dr. Carol Wu from Massachusetts General Hospital and colleagues look at 413 abdominal scan patients with incidental lung nodules that were followed up at least once with chest CT.

Coronary CTA rules out disease for 1-2 years in intermediate-risk patients
Wednesday, December 2 | 10:50 a.m.-11:00 a.m. | SSK03-03 | Room S502ABThere are few outcomes studies with regard to coronary CT angiography's (CTA) ability to diagnose and rule out coronary artery disease. But what people want to know when a CTA test is negative is that there is no coronary artery disease.

Decision tree (often) favors coronary CCTA for chest pain
Wednesday, December 2 | 10:40 a.m.-10:50 a.m. | SSK03-02 | Room S502ABChest pain patients represent an expensive and time-consuming healthcare burden, fraught with risk. Whether coronary CT angiography (CCTA) is a solution to this problem will be discussed in this Wednesday scientific session presentation.

Mortality data correspond to simple 'counting' calcium measure on ungated CT
Tuesday, December 1 | 3:30 p.m.-3:40 p.m. | SSJ05-04 | Room S504ABA simple visual counting assessment of calcium scores in low-dose ungated chest CT provides clinically relevant information that corresponds to patient mortality data, according to a new study from Israel.

Plenty of incidental extracardiac findings at screening CT, few interventions
Tuesday, December 1 | 11:50 a.m.-12:00 p.m. | SSG09-09 | Room S102DIncidental extracardiac findings pose a quandary for reporting radiologists and cardiologists -- it's uncertain whether mentioning them in radiology reports translates into effective management of clinically significant diseases. In this retrospective study, incidental findings were examined in 151 adults undergoing screening coronary CT angiography over a six-year period.

CT team sees eye risks in head scans
Tuesday, December 1 | 11:40 a.m.-11:50 a.m. | SSG19-08 | Room S404ABAn important but often overlooked source of excess radiation in helical CT results from the overranging effect. It is present in all helical CT scans, but it increases with an increasing number of slices. Researchers from the Netherlands assessed the impact on 163 patients undergoing head CT, using 16-, 64-, and 256-slice scanners.
