Ultrasound-guided biopsy is sometimes used to diagnose possible pathology in suspect lesions/changes. Fine-needle biopsy is always used initially. The cell smear is immediately stained and assessed by a cytologist. In most cases, a histological pistol biopsy is also performed (Tru-Cut®). It is often necessary to wait 2-6 days for the result before starting treatment.
- Ambiguous lesions detected with radiological testing.
- Confirm or rule out malignant histology of suspect lesions.
