CT GUIDED FNAC 3.5

CT Guided Fine Needle Aspiration Cytology – English + Bengali SEO Content

CT Guided FNAC (3.5 cm lesion) is an advanced, minimally invasive diagnostic procedure used to obtain cellular samples from deep-seated lesions measuring approximately 3.5 cm.

সহজ ভাষায় বলা যায়, CT Scan-এর সাহায্যে শরীরের গভীরে থাকা প্রায় ৩.৫ সেমি আকারের গাঁট বা লেশন থেকে সূক্ষ্ম সুই দিয়ে কোষ সংগ্রহ করার পরীক্ষাকেই CT Guided FNAC বলা হয়।

What is CT Guided FNAC?

Because CT provides excellent anatomical detail, it allows accurate targeting of 3.5 cm lesions, even when they are located close to vital organs.

Importance of CT Guided FNAC for 3.5 cm Lesions

A 3.5 cm lesion is clinically significant and often requires early diagnosis.

এই পরীক্ষার মাধ্যমে—

• সঠিক জায়গা থেকে কোষ সংগ্রহ করা যায়

• ভুল রিপোর্টের সম্ভাবনা কমে

• আশেপাশের অঙ্গ-প্রত্যঙ্গ নিরাপদ থাকে

Hence, CT Guided FNAC ensures high diagnostic accuracy with maximum patient safety.

Common Indications for CT Guided FNAC (3.5 cm)

Doctors commonly recommend this test when:

• A suspicious mass is detected on CT or MRI

• Malignancy needs confirmation or exclusion

• Infection, abscess, or tuberculosis is suspected

• Cancer staging or treatment planning is required

Common Sites for CT Guided FNAC

CT Guided FNAC (3.5 cm) is frequently performed for lesions in:

• Lung

• Liver

• Pancreas

• Kidney

• Adrenal gland

• Retroperitoneum

• Mediastinum

• Deep lymph nodes

Step-by-Step Procedure

The procedure is done under strict sterile conditions in a CT scan room.

Procedure steps include:

1. Patient positioning according to lesion location

2. CT scan to localize the 3.5 cm lesion

3. Skin sterilization and local anesthesia

4. Needle insertion under CT guidance

5. Aspiration of cellular material

6. Sample sent to pathology laboratory

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

Safety and Comfort

CT Guided FNAC is a safe procedure when performed by trained specialists.

Possible but rare complications include:

• Mild pain or discomfort

• Minor bleeding

• Infection

• Pneumothorax (mainly in lung lesions)

Laboratory Analysis and Reporting

Collected samples are:

• Prepared on glass slides

• Stained using PAP, MGG, or special stains

• Examined by expert cytopathologists

If required, additional tests such as:

• Cell block

• Immunocytochemistry (IHC)

• Molecular studies

⏱️ Report delivery: Usually within 24–72 hours

Interpretation of Results

CT Guided FNAC reports may show:

• Benign lesion

• Malignant cells detected

• Suspicious / Atypical cells

• Inadequate sample (repeat FNAC advised)

Advantages of CT Guided FNAC (3.5 cm)

✔ Minimally invasive
✔ Highly accurate
✔ Avoids surgical biopsy
✔ Faster diagnosis
✔ Cost-effective
✔ Helps early treatment planning
