Lung-RADS Reduces False Positives, But Also Sensitivity
Low-dose CT screening for lung cancer following Lung-RADS criteria may reduce false positives, but it also decreases sensitivity.
Lung cancer screening with low-dose computed tomography may substantially reduce the false-positive result rate, but sensitivity is also decreased, according to a study published in the Annals of Internal Medicine.
Researchers from several states performed a study to assess the retrospective application of the Lung-RADS criteria to the National Lung Screening Trial (NLST).
The study included 26,722 participants (aged 55 to 74) who had undergone three annual low-dose computed tomography (LDCT) scans. The subjects had at least a 30–pack-year history of smoking, and were current smokers or had quit within the past 15 years.
The results showed that 26,455 participants received a baseline screen and 48,671 screenings were performed after baseline.
The researchers concluded that while Lung-RADS may substantially reduce the false-positive result rate, sensitivity is also decreased. They suggest that the effect of using Lung-RADS criteria in clinical practice must be carefully studied.
New Analysis Forecasts Substantial Cost Savings with the Use of Photon Counting CT for CCTA
March 8th 2025The use of ultra-high-resolution photon-counting CT in the evaluation of stable chest pain may significantly reduce follow-up tests and invasive coronary angiography (ICA) procedures, possibly resulting in millions in health-care cost savings, according to a cost-effectiveness analysis presented recently at the European Congress of Radiology.
