What is Guided FNAC Ultrasound Scan?

How Ultrasound-Guided Fine Needle Aspiration Works

1. A high-resolution ultrasound probe locates the lesion.
2. Local anaesthetic numbs the skin.
3. A 23–25 G fine needle is guided in real time to the exact spot.
4. Cells are gently suctioned and sent for cytology.

Equipment Used

• 7–15 MHz linear ultrasound probe
• Sterile, single-use fine needle (23–25 G)
• Local anaesthetic (1% lignocaine)

Duration & Anaesthesia

• 15–30 minutes total
• Local anaesthesia only; no sedation required

Types of Guided FNAC Ultrasound Scan

• Thyroid FNAC – for cold or hot nodules
• Lymph-node FNAC – cervical, axillary, inguinal nodes
• Breast FNAC – solid lumps or complex cysts
• Superficial soft-tissue FNAC – lipomas, ganglia, skin nodules

• Lesion size & echogenicity
• Vascularity on colour Doppler
• Needle approach path avoiding vessels
• Sample adequacy confirmed by on-site cytotechnologist

• Confirm benign vs malignant nature
• Avoid unnecessary surgery for harmless cysts
• Guide treatment plan—surgery, chemotherapy, or observation

• Thyroid nodules discovered on routine ultrasound
• Lymph-node swelling persisting >2 weeks
• Breast or soft-tissue lumps felt on self-exam
• Follow-up of cancer patients checking for recurrence

Benefits of Taking the Guided FNAC Ultrasound Scan

• Minimally invasive—no stitches
• Real-time imaging accuracy—hits the bull’s-eye
• Cost-effective diagnosis—fraction of open-biopsy cost
• Same-day return to activities—resume work immediately

Illnesses Diagnosed with Guided FNAC Ultrasound Scan

• Thyroid cancer (papillary, medullary)
• Lymphoma
• Metastatic carcinoma from unknown primary
• Benign cysts or adenomas

• Fasting not required
• Continue regular medications unless advised to stop anticoagulants
• Wear loose clothing; jewellery around neck/breast area to be removed

Pre-requisites Guided FNAC Ultrasound Scan

• Valid doctor prescription
• Recent ultrasound or CT images, if available
• Coagulation profile (PT/INR) if on blood thinners

Best Time to Take the Guided FNAC Ultrasound Scan

• Menstrual cycle timing: days 5–10 for breast lesions minimizes cystic changes
• Morning slots: shorter fasting and quicker recovery
• Book within 1–2 weeks of initial lump detection for prompt answers

Eligibility

Procedure for Taking a Guided FNAC Ultrasound Scan

1. Check-in & consent – ID verification, explanation of risks
2. Positioning – lying flat or slight neck extension
3. Local anaesthesia – tiny sting, then numbness
4. Ultrasound guidance & needle insertion – 1–3 passes
5. Sample collection & pressure dressing – 5 minutes of firm pressure, adhesive bandage

Caution Before Taking the Test

• Discontinue anticoagulants only if your doctor and our radiologist agree
• Inform of allergy to local anaesthetic
• Bring an escort if you feel anxious or are coming from out of town
