A study has shown that using both plain and contrast-enhanced CT scans can significantly improve the diagnosis of solitary solid lung nodules, which can be either benign or cancerous. Researchers compared two diagnostic approaches: one based on plain CT scans alone and another that combined plain and contrast-enhanced scans. The study looked at 527 patients from two medical centers who had confirmed solid lung nodules.
The results showed that the combined approach was more accurate, with a 90% success rate in correctly identifying whether the nodules were malignant, compared to 79% with the plain CT model. The contrast-enhanced model also proved to be more sensitive and specific in distinguishing between benign and malignant nodules.
This improved diagnostic performance could help doctors make better decisions about whether to closely monitor lung nodules or recommend surgery. For patients, especially those at risk of lung cancer, these findings could lead to earlier and more accurate diagnoses.
