Imaging Features of Lung Ground-Glass Nodules and Their Correlation With Biological Behavior

Area of Science:

• Pulmonary imaging and diagnostic radiology.
• Thoracic oncology and lung cancer research.
• Medical imaging analysis and interpretation.

Background:

• Ground-glass nodules (GGNs) are common pulmonary imaging findings with malignant potential.
• Increased detection due to low-dose CT screening presents diagnostic challenges.
• Existing research links GGN imaging features to pathology but gaps remain regarding prognosis.

Purpose of the Study:

• To systematically review the latest research on lung GGN imaging characteristics and biological behavior.
• To explore the application of GGN imaging in pathological typing, molecular marker expression, and prognosis.
• To provide evidence for clinical risk stratification, personalized treatment, and follow-up strategies for lung cancer.

Main Methods:

• Literature search of the PubMed/MEDLINE database.
• Keywords included GGO, alveolar wall shadows, part-solid nodules, and subsolid nodules.
• Analysis of studies on GGN imaging features, biological behavior, and clinical applications.

Main Results:

• GGN imaging characteristics are diverse and linked to pathological types and molecular markers.
• Correlations between imaging features, tumor behavior, and prognosis require further clarification.
• GGNs are valuable for assessing lung cancer risk, guiding treatment, and follow-up.

Conclusions:

• Understanding GGN imaging features is crucial for early lung cancer diagnosis and precise treatment.
• Further research is needed to solidify the link between GGN imaging, biological behavior, and patient outcomes.
• This review supports evidence-based clinical decision-making for lung GGNs.
