Guiding biopsies involves using imaging techniques to accurately locate the tissue area that needs to be sampled. Common methods include:
1. Ultrasound-Guided Biopsy: Uses sound waves to visualize tissues and guide the needle. 2. CT-Guided Biopsy: Utilizes computer tomography for precise needle placement. 3. MRI-Guided Biopsy: Magnetic resonance imaging helps in targeting specific areas within the body.
