Researchers also found that low-dose chest CT detection of emphysema was associated with a 29 percent higher risk of all-cause mortality up to 25 years later, according to a study involving over 9,000 individuals with a history of smoking.

For myocardial extracellular volume quantification, single-phase and dual-phase photon-counting CT provided over 20 percent higher correlation with cardiac MRI in contrast to dual-phase energy-integrating detector CT, according to new research findings.

Offering the capability to convert a non-contrast chest CT into quantitative ventilation perfusion mapping, use of the CT:VQ software allows for additional Category III CPT reimbursement beyond the chest CT.

In a long-term follow-up analysis of the ELCAP CAC score for predicting cardiovascular mortality, over 30 percent of current or former smokers with high ELCAP CAC scoring on low-dose CT suffered cardiovascular disease death within a 25-year period.
