Eric Barnes[email protected]CTDynamic myocardial stress CT perfusion appears feasible and accurateWednesday, December 1 | 10:30 a.m.-10:40 a.m. | SSK03-01 | Room S503ABCardiac MRI could potentially face some competition from adenosine-stress first-pass myocardial CT perfusion, according to an initial study from the Medical University of South Carolina in Charleston. The study won an RSNA trainee research prize for Markus Weininger, MD, who will discuss his group's initial experience with the dual-source CT technique.November 10, 2010CTQuantitative CT evaluates emphysema, air trappingTuesday, November 30 | 10:40 a.m.-10:50 a.m.| SSG03-02 | Room S504ABIf individualized medicine is the new mantra, emphysema evaluation is one of its most promising potential applications. Radiologists from National Jewish Health in Denver compared quantitative CT measurements of emphysema to physiologic measures of disease severity.November 10, 2010CT320-detector-row perfusion CT nabs malignant lung nodulesTuesday, November 30 | 9:15 a.m.-9:25 a.m. | VC31-04 | Room S404CDDistinguishing malignant from benign lung nodules using PET is tricky business, notably because not all lung cancers are glucose-avid. But in this Tuesday morning presentation, researchers from Kobe, Japan, will discuss how they found that perfusion CT on a 32-detector-row scanner and MRI both perform better than PET/CT for distinguishing malignant from benign nodules.November 10, 2010CTAutomatic kV selection tool simplifies scansTuesday, 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?November 10, 2010CTVC findings in Medicare patients similar to younger populationMonday, 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.November 10, 2010CTObesity no barrier to renal stone discrimination in dual-energy CTMonday, 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.November 10, 2010CTCT drives imaging growth in emergency departmentsMonday, 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.November 10, 2010CTPulmonary CTA accurately predicts right ventricular dysfunctionSunday, 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.November 10, 2010CTTriple-rule-out plus CAD gets the nodules radiologists missSunday, 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.November 10, 2010CTAutomated tool speeds clot burden assessment in PE patientsSunday, 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.November 10, 2010Previous PagePage 114 of 258Next PageTop StoriesMRIMRI may help guide brachial plexus surgeryMRI-based volumetric analysis of paraspinal muscles can distinguish the severity of traumatic brachial plexus injury.AIShould hospitals pursue local domain LLM adaptation for radiology reports?Womens ImagingMRI model predicts breast tumor shrinkage patternsMRICheck for middle neck involvement for nasopharyngeal cancer prognosisMolecular ImagingPET links brain receptor to emotional numbing in PTSD
