CT-Guided Aspiration, Biopsy & Drainage

What is CT-Guided Aspiration, Biopsy & Drainage?

CT-guided procedures are minimally invasive techniques performed using CT (Computed Tomography) imaging to precisely target abnormal tissues, fluid collections, or masses.
This advanced technology allows the doctor to reach deep areas of the body safely and accurately for diagnosis and treatment—without major surgery.

These procedures help:
✔ Diagnose diseases
✔ Remove infected or unwanted fluid
✔ Obtain tissue samples for laboratory testing
✔ Treat abscesses & fluid collections
✔ Avoid open surgical interventions

Benefits of CT-Guided Procedures

  • High accuracy due to real-time CT image guidance

  • Minimally invasive with tiny skin puncture

  • Short recovery time

  • Less pain and discomfort

  • Reduced risk of complications

  • Day-care / short hospital stay

1️⃣ CT-Guided Aspiration

Aspiration involves removing fluid from cysts, abscesses, or collections using a fine needle under CT scan guidance.

Common Reasons for Aspiration:

  • Lung or liver abscess

  • Pancreatic fluid collections

  • Kidney or abdominal cysts

  • Pleural or peritoneal effusion

  • Infection-related collections

Why It is Done:

  • Diagnosis of infection or malignancy

  • Reducing pain, fever, swelling

  • Therapeutic fluid removal

2️⃣ CT-Guided Biopsy

A biopsy is performed to take a small tissue sample for microscopic examination.

Conditions Requiring Biopsy:

  • Suspicious tumors

  • Lung nodules

  • Liver lesions

  • Kidney masses

  • Bone or soft tissue lesions

  • Lymph nodes

Advantages:

  • Accurate diagnosis of cancer or benign disease

  • Early detection

  • Helps plan the best treatment (surgery / chemo / radiation)

3️⃣ CT-Guided Drainage

This procedure involves placing a catheter to continuously drain infected fluid, pus, or collections.

Ideal For Treating:

  • Deep abscesses (abdominal, pelvic, lung)

  • Post-surgical collections

  • Pancreatic fluid / pseudocyst

  • Pleural empyema

Benefits:

  • Avoids major surgery

  • Immediate relief from symptoms

  • Helps control infection and sepsis

How the Procedure is Performed

1️⃣ Local anesthesia is given (general anesthesia rarely needed)
2️⃣ A small skin incision is made
3️⃣ Needle or catheter is guided using CT imaging
4️⃣ Fluid/tissue is aspirated or catheter placed
5️⃣ Sample is sent to laboratory
6️⃣ Dressing applied

Duration: 20–45 minutes in most cases
Hospital stay: Same day or one night

Before the Procedure

You may be advised:

  • Routine blood tests

  • Stop blood thinners temporarily

  • Fast for a few hours

  • Bring imaging (MRI / ultrasound / CT) if available

After the Procedure

  • Mild soreness expected

  • Results shared within a few days (biopsy)

  • Drain removed once fluid clears (for drainage)

  • You can resume routine activities soon

Risks & Safety

CT-guided procedures are very safe.
Rare risks may include:

  • Minor bleeding

  • Infection

  • Pain or discomfort

  • Pneumothorax (lung biopsy cases)

Your interventional radiologist ensures maximum safety using modern techniques and imaging.

Why Choose a Consultant Interventional Radiologist?

  • Specialized expertise

  • Precision targeting under CT guidance

  • Minimally invasive approach

  • Better outcomes & faster recovery

Who Needs These Procedures?

Patients with:

  • Suspicious masses

  • Unexplained swelling

  • Fluid collections

  • Fever with abscess

  • Organ lesions

  • Cancer diagnosis confirmation
