CT GUIDED FNAC 3.0

What is CT Guided FNAC?

CT Guided FNAC stands for Computed Tomography Guided Fine Needle Aspiration Cytology. In this procedure, a CT scanner provides real-time imaging to guide a thin needle precisely into a suspicious lesion, ensuring accurate sample collection for cytological examination.

Because of its precision, this technique is especially useful when:

• The lesion size is around 3.0 cm

• The lesion is located deep inside the body

• Surrounding vital organs or blood vessels must be avoided

Why CT Guided FNAC is Ideal for 3.0 cm Lesions?

A 3.0 cm lesion is large enough to yield a good cellular sample but may still be difficult to access safely without imaging guidance. Therefore, CT guidance plays a crucial role.
As a result, it ensures:

• Accurate localization of the lesion

• Proper needle placement

• Minimal damage to surrounding tissues

• High diagnostic yield

Common Sites for CT Guided FNAC (3.0 cm)

CT Guided FNAC is commonly performed for lesions in:

• Lung (pulmonary nodules or masses)

• Liver

• Pancreas

• Kidney

• Adrenal gland

• Retroperitoneal space

• Mediastinum

• Deep-seated lymph nodes

When is CT Guided FNAC Recommended?

Doctors usually advise CT Guided FNAC (3.0 cm) in the following situations:

• Suspicious lesion detected on CT or MRI

• To confirm or rule out cancer

• For staging of malignancy

• To diagnose infections like tuberculosis or abscess

• When ultrasound-guided FNAC is not feasible

Therefore, CT Guided FNAC helps clinicians plan the most appropriate treatment at an early stage.

Procedure of CT Guided FNAC

The procedure is performed under strict aseptic precautions in a CT scan room.

Step-by-step process:

1. Patient positioning according to lesion location

2. Initial CT scan to localize the 3.0 cm lesion

3. Cleaning of the skin and local anesthesia

4. Fine needle insertion under CT guidance

5. Aspiration of cellular material

6. Sample transfer to pathology laboratory

⏱️ Duration: Usually 20–30 minutes
✔ Mostly done as a day-care procedure

Safety and Patient Comfort

CT Guided FNAC is generally safe and well tolerated. Most patients feel only mild discomfort.

Possible but rare complications include:

• Minor bleeding

• Infection

• Pneumothorax (especially in lung lesions)

However, when performed by experienced radiologists, complications are uncommon.

Laboratory Processing & Reporting

The collected samples are:

• Prepared as cytology smears

• Stained using PAP, MGG, or special stains

• Examined by experienced cytopathologists

If required, additional tests like:

• Cell block preparation

• Immunocytochemistry (IHC)

• Molecular studies

⏱️ Report availability: Usually within 24–72 hours

Interpretation of CT Guided FNAC Report

• Benign – Non-cancerous condition

• Malignant – Cancerous cells detected

• Suspicious / Atypical – Further biopsy advised

• Inadequate – Repeat FNAC may be needed

Advantages of CT Guided FNAC (3.0 cm)

✔ High diagnostic accuracy
✔ Minimally invasive
✔ Avoids open surgical biopsy
✔ Faster diagnosis
✔ Cost-effective
✔ Helps in early treatment planning
