Automatic kV selection tool simplifies scans
By Eric Barnes
Tuesday, November 30 | 8:35 a.m.-8:45 a.m. | VV31-02 | Room E353ATo reduce CT radiation exposure, radiologists have gotten used to adjusting kV based on body mass index and the diagnostic task at hand. But how about doing it quantitatively and automatically?

Obesity no barrier to renal stone discrimination in dual-energy CT
By Eric Barnes
Monday, November 29 | 11:10 a.m.-11:20 a.m.| SSC14-05 | Room S403BIncreased image noise seen in CT scans of obese patients does not prevent accurate discrimination of renal stone types -- provided additional filtration is used, according to a study from the Mayo Clinic in Rochester, MN, to be presented on Monday.

CT unnecessary in most blunt trauma admissions
By Eric Barnes
Sunday, November 28 | 11:05 a.m.-11:15 a.m. | SSA05-03 | Room N227Blunt trauma patients admitted to emergency departments are routinely scanned with CT of the chest, abdomen, and pelvis. But are all those scans really necessary in the absence of serious signs of injury? No, say Noam Millo, MD, and colleagues from the University of Alberta in Edmonton.

MRI useful in evaluating pregnant patients with right lower quadrant pain
By Wayne Forrest
Wednesday, December 1 | 11:50 a.m.-12:00 p.m. | SSK08-09 | Room S102DMRI is valuable in evaluating pregnant patients with right lower quadrant pain, according to a new scientific paper by researchers from Johns Hopkins University in Baltimore.

Can DWI-MRI replace contrast-enhanced MRI for hepatic metastases?
By Wayne Forrest
Thursday, December 2 | 11:50 a.m.-12:00 p.m. | SSQ06-09 | E353AIn this paper presentation, Italian researchers will offer that even though diffusion-weighted imaging (DWI) MRI should not be substituted for contrast-enhanced MRI to assess hepatic metastases, DWI does improve overall metastatic lesion detection when combined with MRI enhanced with a liver-specific contrast agent.

MRI, CT fall short in distinguishing malignant cystic pancreatic masses
By Wayne Forrest
Thursday, December 2 | 11:40 a.m.-11:50 a.m. | SSQ07-08 | Room E350CT and MRI may not be reliable in distinguishing benign from malignant cystic masses of the pancreas, according to a study by researchers from Hôpital Saint-Luc in Montreal.

MR enterography a 'favorable' option for evaluating Crohn's disease
By Wayne Forrest
Tuesday, November 30 | 3:50 p.m.-4:00 p.m. | SSJ08-06 | Room E353AResearchers of a new study to be presented on Tuesday concluded that MR enterography compares favorably to endoscopy for evaluating known or suspected Crohn's disease -- and it does so in a noninvasive manner without exposing patients to ionizing radiation.

3T matches 1.5T MR in evaluating ileocolonic Crohn's disease
By Wayne Forrest
Tuesday, November 30 | 3:20 p.m.-3:30 p.m. | SSJ08-03 | Room E353AIn this scientific paper, Italian researchers recommend the use of 3-tesla MRI for patients with ileocolonic Crohn's disease because of the modality's superiority in detecting mucosal ulcers, increased signal-to-noise ratio, and reduced image acquisition time.

MRI, DWI-MRI both accurate in pediatric appendicitis diagnosis
By Wayne Forrest
Monday, November 29 | 3:00 p.m.-3:10 p.m. | SSE20-01 | Room N230Dutch researchers have found that both MRI and diffusion-weighted imaging (DWI) MRI achieve high accuracy in diagnosing appendicitis in pediatric patients, with negative predictive value and positive predictive value of MRI comparable to CT.
