What is CT-Guided Percutaneous Biopsy?

CT-guided percutaneous biopsy is a procedure in which a needle is placed under computed tomography guidance to obtain tissue samples from deep organ and tissue lesions for histopathological examination. Two techniques are used: fine needle aspiration biopsy (FNAB) and tru-cut (core) biopsy.

It is performed for diagnostic purposes in lung, liver, kidney, retroperitoneal, bone and soft tissue lesions. The technique is planned according to the lesion size, location and patient cooperation.

The procedure is done under local anesthesia on an outpatient or day-case basis. The complication rate is low; in lung biopsy, pneumothorax (10-25%) is the most common complication.

Symptoms

Histopathological diagnosis of lung nodules/masses
Characterization of liver masses
Renal mass biopsy
Diagnosis of retroperitoneal lymphadenopathy
Bone lesion biopsy

Risk Factors

Bleeding diathesis (INR >1.5, platelets <50,000)
Anticoagulant/antiplatelet therapy
Pneumothorax (in lung biopsy)
Emphysema (increases pneumothorax risk)
Inability to cooperate

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

  • When a deep organ lesion cannot be diagnosed by imaging
  • For histopathological diagnosis of suspicious malignant masses
  • When investigating the primary focus in metastatic disease
  • When tissue diagnosis is needed for treatment planning

Treatment Methods

01
Pre-procedure coagulation tests and medication review
02
CT-guided needle placement under local anesthesia
03
Fine needle aspiration or tru-cut (core) biopsy
04
Post-procedure control CT (complication screening)
05
2-4 hours observation and chest X-ray after lung biopsy
