Computed Tomography

9.4K
Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Area of Science:

  • Medical Imaging
  • Pulmonology
  • Interventional Radiology

Background:

  • Transthoracic fine needle aspiration biopsy (T-FNAB) is a key diagnostic tool for lung lesions.
  • Optimizing CT-guided T-FNAB technique is crucial for diagnostic yield and patient safety.

Purpose of the Study:

  • To evaluate the technique, sensitivity, and complication rate of CT-guided T-FNAB.
  • To analyze outcomes in patients undergoing T-FNAB for lung lesion diagnosis.

Main Methods:

  • Retrospective review of 32 patients undergoing CT-guided T-FNAB.
  • Biopsies performed using spinal or Chiba needles.
  • Data collected on procedure technique, diagnostic sensitivity, and complications.

Main Results:

  • Pneumothorax occurred in 7 patients (21.9%).
  • Transient postbiopsy haemoptysis occurred in 2 patients (6.3%).
  • No pneumothorax or haemoptysis cases required treatment.

Conclusions:

  • CT-guided T-FNAB is an effective and safe procedure for diagnosing lung lesions.
  • The complication rate is low, and complications are generally manageable without intervention.
  • This technique offers a valuable diagnostic option with minimal adverse events.
