CT Guided Lung Biopsy

Overview

6procs_ct-biospy.webp

A CT-guided lung biopsy is a minimally invasive procedure used to obtain a small sample of lung tissue for examination under a microscope. It is typically performed when a lung abnormality, such as a mass or nodule, is detected through imaging tests. The procedure uses computed tomography (CT) imaging to guide a needle precisely into the lung abnormality to collect the sample.

Step-by-Step Process

  • Patient Positioning: The patient lies on the CT table in a position that provides the best access to the lung lesion.
  • Initial CT Scan: A preliminary CT scan is performed to locate the lesion.
  • Skin Sterilization & Anesthesia: The skin is cleaned, and a local anesthetic is injected to numb the area.
  • Needle Insertion: A small incision is made, and a thin biopsy needle is inserted into the lung under CT guidance.
  • Tissue Sampling: The doctor extracts small tissue samples.
  • Needle Removal & Bandaging: The needle is withdrawn, and a small bandage is applied.
  • Post-Biopsy CT Scan: A final CT scan is done to check for complications.
  • Monitoring & Discharge: The patient is monitored for a few hours before being discharged.

How is CT Guided Lung Biopsy Done?

Before undergoing a CT-guided lung biopsy, patients should follow these preparatory steps:
  • Medical History & Physical Examination: The doctor will review the patient’s medical history and perform a physical exam.
  • Blood Tests: These help assess clotting function to minimize the risk of bleeding.
  • Fasting: Patients may need to fast for a few hours before the procedure.
  • Medication Adjustments: Certain blood thinners, such as aspirin or warfarin, may need to be stopped temporarily.
  • Informed Consent: The procedure risks and benefits will be explained, and the patient must sign a consent form.

  • Type of Anesthesia: The procedure is typically performed under local anesthesia.
  • Duration: The biopsy usually takes 30 to 60 minutes, with additional time for observation.
  • Imaging: A CT scan is taken before the biopsy to locate the exact position of the abnormality.
  • Needle Insertion: A thin biopsy needle is inserted into the lung lesion under CT guidance.
  • Sample Collection: Multiple tissue samples may be collected to improve diagnostic accuracy.
  • Post-Procedure Monitoring: The patient is observed for a few hours to check for complications, such as pneumothorax (collapsed lung).

While CT-guided lung biopsy is generally safe, potential complications include:
  • Pneumothorax (Collapsed Lung): Air may leak into the pleural space, causing lung collapse.
  • Bleeding (Hemoptysis): Some patients may cough up blood, though it’s usually minor.
  • Infection: Rare but possible.
  • Breathing Difficulties: Temporary shortness of breath may occur.
What are the Benefits of CT Guided Lung Biopsy ?
  • Minimally Invasive: No need for open surgery.
  • Accurate Diagnosis: Helps in diagnosing lung conditions, including cancer and infections.
  • Quick Recovery: Most patients return to normal activities within a day.

Infrastructure Facilities

  • Advanced CT Scanner for real-time imaging.
  • Sterile Biopsy Room equipped with necessary instruments.
  • Emergency Equipment to manage complications.
  • Pathology Lab for tissue sample analysis.
  • Post-Procedure Observation Area for patient monitoring.

FAQs

Mild discomfort is common, but local anesthesia minimizes pain.

Most patients can resume normal activities within 24 hours.

You may need to fast for a few hours before the biopsy.

Avoid strenuous activities and heavy lifting for 24–48 hours.

Typically within 3 to 7 days, depending on the pathology lab.
