    What Is Ct-Guided Biopsy?

    A minimally invasive image-guided procedure in which CT imaging is used to accurately place a needle into a lesion to obtain tissue for histopathology or cytology.

    Indications

    Lung Mass

    • Suspected primary lung malignancy
    • Metastatic lesion
    • Solitary pulmonary nodule
    • Infection (e.g. TB, fungal) when sputum negative

    Mediastinal Tumors

    • Anterior/middle mediastinal masses
    • Lymphoma
    • Thymoma/germ cell tumor evaluation
    • Metastatic lymphadenopathy

    Retroperitoneal Nodes

    • Para-aortic/paracaval lymphadenopathy
    • Lymphoma staging
    • Unknown primary malignancy workup
    • Infective nodes (e.g. TB)

    Procedure Technique: Step By Step

    CT-GB

    01.Pre-procedure Planning

    1

    Review clinical details, previous imaging. Choose safest and shortest needle path. Check coagulation profile & consent.

    Jan

    02.Patient Positioning

    2

    Position patient (prone/supine/lateral) depending on lesion location.

    Jan

    03.Sterile Preparation & Local Anaesthesia

    3

    Aseptic cleaning and draping. Local anaesthesia to skin and deeper tissues.

    Jan

    04.Needle Insertion under CT Guidance

    4

    Stepwise needle advancement with intermittent CT scans. Coaxial technique commonly used.

    Jan

    05.Tissue Sampling

    5

    Obtain FNAC and/or core tissue using biopsy needle or automated biopsy gun.

    Jan

    06.Post-procedure Scan

    6

    Immediate CT scan to check for complications (pneumothorax, bleeding, etc.).

    Jan

    07. Observation

    7

    Observe patient for 2-4 hours (longer for lung biopsy). Monitor vitals and symptoms.

    Jan

    Contraindications

    • Uncorrected coagulopathy (INR >1.5)
    • Severe thrombocytopenia (Platelets <50,000/µL)
    • Uncooperative or non-compliant patient
    • Vascular lesion or pseudoaneurysm suspected
    • Severe respiratory compromise (relative for lung biopsy)
    • Inaccessible lesion / unsafe needle trajectory
    • Active infection at puncture site

    ADVANTAGES

    Minimally invasive

    High diagnostic accuracy

    Real-time precise targeting

    Avoids open surgical biopsy

    Wide range of accessible lesions

    Short hospital stay / day care procedure

    Cost-effective with good safety profile

    Potential Complications

    Lung Biopsy

    • Pneumothorax (most common)
    • Hemoptysis
    • Pulmonary hemorrhage

    Mediastinal Biopsy

    • Bleeding/hematoma
    • Injury to vessels, trachea, esophagus
    • Pneumothorax (rare)

    Retroperitoneal Biopsy

    • Bleeding/retroperitoneal hematoma
    • Injury to bowel, kidney, major vessels
    • Infection (rare)

    Key Points

    • Use the shortest and safest needle path
    • Coaxial needle system reduces multiple pleural punctures
    • Avoid vessels and vital structures (use contrast CT if needed)
    • Adequate post-procedure monitoring is essential
    • Send adequate tissue for histopathology, IHC, microbiology as needed

    Examples Of Lesions

    Lung Mass
    Mediastinal Tumor
    Retroperitoneal Node

    Important Advice

    • CT-guided biopsy is a safe and effective procedure when performed by experienced operators with proper patient selection and technique.
