Automatic kV selection tool simplifies scans

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?

VC findings in Medicare patients similar to younger population

Monday, November 29 | 3:40 p.m.-3:50 p.m. | SSE08-05 | Room E450BIn this scientific session, researchers from the Mayo Clinic in Rochester, MN, will discuss the examination of more than 1,000 Medicare-aged patients with virtual colonoscopy. Their results showed the prevalence of polyps and extracolonic findings to be similar to those of younger populations.

Obesity no barrier to renal stone discrimination in dual-energy CT

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 drives imaging growth in emergency departments

Monday, November 29 | 9:05 a.m.-9:15 a.m. | VE21-02 | Room N227Imaging utilization in emergency departments has grown every year from 2000 to 2008 -- but CT is far and away the biggest driver of imaging utilization, according to Vijay Rao, MD, and colleagues from Thomas Jefferson University in Philadelphia. And it's mostly radiologists doing it.

Pulmonary CTA accurately predicts right ventricular dysfunction

Sunday, November 28 | 1:00 p.m.-1:30 p.m. | LL-ERS-SU2B | Lakeside Learning CenterPulmonary CT angiography (CTA) could potentially replace a biomarker used to assess right ventricular dysfunction, according to a novel study to be presented on Sunday by researchers from the Medical University of South Carolina in Charleston.

Triple-rule-out plus CAD gets the nodules radiologists miss

Sunday, November 28 | 12:30 p.m.-1:00 p.m. | LL-ERS-SU2A | Lakeside Learning CenterTriple-rule-out scans are often read by emergency department radiologists with concern about their patients' chest pain, but who often have no subspecialty training in thoracic radiology. Lung nodules will be missed. Fortunately, computer-aided detection (CAD) might help find them.

Automated tool speeds clot burden assessment in PE patients

Sunday, November 28 | 11:35 a.m.-11:45 a.m. | SSA04-06 | Room S404CDGauging the clot burden in pulmonary embolism (PE) patients at CT pulmonary angiography is important for management and treatment. For most but not all patients, assessment can be performed faster using an automated clot burden assessment tool, researchers will report in this Sunday session.

CT perfusion gauges sarcoma treatment response

Sunday, November 28 | 11:25 a.m.-11:35 a.m. | SSA13-05 | Room E451BIn this scientific presentation, researchers from Massachusetts General Hospital in Boston will discuss their successful use of CT perfusion imaging to monitor the response to sarcoma treatment. Both tumor size and density differences were visible after antiangiogenic therapy for soft-tissue sarcomas.

CT unnecessary in most blunt trauma admissions

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.

Individualized contrast injection keeps up with triple-rule-out CT

Sunday, November 28 | 10:55 a.m.-11:05 a.m. | SSA04-02 | Room S404CDOutrunning the contrast bolus can be a real problem with state-of-the art CT equipment that scans the thorax in less than a second. But J. Michael Barraza and colleagues from the Medical University of South Carolina in Charleston found excellent results with a contrast injector equipped with an individualized patient-based contrast media injection algorithm.

Road to RSNA 2010: CT Preview

At this year's RSNA conference, technical innovation leading to speed and image sharpness continue to make CT popular with radiologists and bean counters alike. Also look for vendors to demonstrate their efforts in reducing radiation dose delivered by the modality.
