Steelworkers call for routine lung cancer screening
By AuntMinnie.com staff writers
If CT lung cancer screening works -- and it does, according to results of a 10-year trial released last week by the U.S. National Cancer Institute -- then steelworkers need it now, the United Steelworkers said on Wednesday.

Quantitative CT evaluates emphysema, air trapping
By Eric Barnes
Tuesday, 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.

320-detector-row perfusion CT nabs malignant lung nodules
By Eric Barnes
Tuesday, 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.

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?

Pulmonary CTA accurately predicts right ventricular dysfunction
By Eric Barnes
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
By Eric Barnes
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
By Eric Barnes
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 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.

Individualized contrast injection keeps up with triple-rule-out CT
By Eric Barnes
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.

NLST results show drop in lung cancer deaths with CT screening
By Eric Barnes
Low-dose CT screening for lung cancer cuts lung cancer deaths by more than 20%, the U.S. National Cancer Institute announced in its release of early results from the National Lung Screening Trial (NLST).

Bifurcation filter cuts false positives in lung CAD
By Eric Barnes
Researchers from Japan believe they have found a way to distinguish blood vessel bifurcations from solitary pulmonary nodules in computer-aided detection (CAD) applications for lung cancer screening.
