Lung Biopsy Alternatives: Imaging & Diagnostic Options

Alternatives to lung biopsy include:

1. Imaging: HRCT (detailed lung images), MRI (mediastinal masses), PET scan (benign vs. malignant, metabolic activity).
2. Sputum cytology: Microscopic exam of coughed mucus; less conclusive but can detect cancer cells.
3. Bronchoscopy with washings/brushings: Collects airway cells via flexible scope.
4. Fine-needle aspiration (FNA) with ultrasound: Targeted sampling of lesions, lower risk.
5. Liquid biopsy: Blood test for circulating tumor cells/DNA; minimally invasive, evolving.
6. Clinical/radiographic follow-up: Monitoring instead of immediate biopsy if findings not alarming or patient unfit.

Choice depends on clinical presentation, suspected condition, patient preference, and resources. A pulmonologist or thoracic surgeon can guide the best approach.
