CT GUIDED INTERVENTION FNAC (Code 1658)

Advanced CT Scan Guided Fine Needle Aspiration Cytology

CT Guided Intervention FNAC (Code 1658) is an advanced, image-guided diagnostic procedure used to collect cellular samples from deep-seated, non-palpable, or complex lesions inside the body with the help of Computed Tomography (CT) scan guidance. This test plays a vital role in the early detection of cancer, infections, inflammatory diseases, and other pathological conditions.

What is CT Guided Intervention FNAC?

CT Guided FNAC stands for Computed Tomography Guided Fine Needle Aspiration Cytology. In this procedure, a very thin needle is precisely guided into the lesion under continuous CT imaging.

• Accurate needle placement

• Maximum tissue yield

• Minimal damage to surrounding organs

Why CT Guided Intervention FNAC (Code 1658) is Important

Many lesions inside the body cannot be accessed safely through routine FNAC or ultrasound guidance.

• Deep-seated lesion থেকে নির্ভুলভাবে sample নেওয়া যায়

• Surgery ছাড়াই রোগ নির্ণয় সম্ভব

• Early cancer detection-এ সাহায্য করে

• Treatment planning সহজ হয়

Indications for CT Guided Intervention FNAC

A suspicious mass is seen on CT / MRI

• Malignancy (cancer) needs confirmation

• Tuberculosis or chronic infection is suspected

• Abscess or inflammatory lesion evaluation is required

• Tumor recurrence needs assessment

Common Sites Where CT Guided FNAC is Performed

CT Guided Intervention FNAC is commonly done for lesions located in:

• Lung

• Liver

• Pancreas

• Kidney

• Adrenal gland

• Mediastinum

• Retroperitoneal space

• Deep lymph nodes

• Pelvic masses

Procedure of CT Guided Intervention FNAC (Code 1658)

The procedure is usually performed in a CT scan suite under strict aseptic conditions.

Step-by-step process:

1. Patient positioning based on lesion location

2. Initial CT scan to localize the lesion

3. Skin cleaning and local anesthesia

4. Needle insertion under CT guidance

5. Aspiration of cellular material

6. Sample preservation and laboratory processing

Safety and Possible Complications

Rare complications may include:

• Mild pain or discomfort

• Minor bleeding

• Infection

• Pneumothorax (in lung FNAC cases)

তবে সঠিক গাইডেন্স ও অভিজ্ঞতার কারণে জটিলতার ঝুঁকি খুবই কম।

Laboratory Analysis & Reporting

Collected samples are:

• Prepared on slides

• Stained using PAP / MGG / special stains

• Evaluated by trained cytopathologists

Cell block

• Immunocytochemistry (IHC)

• Molecular studies
