A new deep learning model using a large-scale dataset demonstrated near-expert-level accuracy in detecting and segmenting lung tumors on CT scans, offering potential for automating tasks like treatment planning and tumor burden assessment, though physician oversight remains essential for handling limitations.
Low-dose CT scans reduce the sensitivity of CAD systems in detecting small lung nodules in pediatric patients, especially for nodules smaller than 5 mm, according to a study comparing standard and low-dose scans.
Patients with stage I NSCLC with a small ground-glass opacity (GGO) component on preoperative CT have a significantly better prognosis, including five-year recurrence-free and cancer-specific survival, compared to those with a pure-solid appearance.
