Data sampling technique cuts CT lung dose to 0.25 mSv

By Eric Barnes

How low can chest CT doses really go? Researchers from Boston may have bested even the chest x-ray, the ultimate low-dose scan, using a special data sampling technique to produce diagnostic-quality CT lung screening scans at doses as low as 0.25 mSv.

Study finds overdiagnosis in CT lung screening

By Eric Barnes

A new analysis of National Lung Screening Trial data has found that as many as one-fifth of all lung cancer diagnoses may represent overdiagnosis -- that is, detection of indolent or slow-growing lung cancers that may never have harmed the patient, according to a report in JAMA Internal Medicine.

CT screening: Few ground-glass nodules go rogue, but 10% grow

By Eric Barnes

CHICAGO - A large Japanese lung cancer screening study found that few solid ground-glass nodules 5 mm and smaller grow to become invasive adenocarcinomas -- even when followed for five years or longer, according to a Tuesday presentation at RSNA 2013.

High-pitch CTPA outperforms standard PE protocol

By Eric Barnes

In patients with suspected pulmonary embolism (PE), a CT pulmonary angiography (CTPA) protocol using high-pitch dual-source electrocardiogram-synchronized helical scanning outperformed standard pulmonary CTA by almost every measure, according to an article in the American Journal of Roentgenology.
