Area of Science:

Radiology
Interventional Radiology
Oncology

Background:

Accurate tissue diagnosis is crucial for managing mass lesions.
Image-guided biopsy techniques are essential for precise sampling.

Purpose of the Study:

To evaluate the utility of contrast-enhanced computed tomographic (CT) scans in guiding Fine Needle Aspiration Cytology (FNAC) and Tru-cut biopsies.
To assess CT's role in ensuring optimal needle placement and sample adequacy for mass lesions.

Main Methods:

Twenty-five patients with mass lesions underwent contrast-enhanced CT scans.
CT-guided FNAC or Tru-cut biopsies were performed for tissue sampling.
Post-procedure CT scans were utilized to assess for complications.

Main Results:

CT scans proved highly valuable for precise needle placement within target lesions.
CT guidance facilitated avoidance of necrotic tissue, enhancing sample quality.
Post-procedure scans effectively identified any complications.

Conclusions:

CT-guided biopsy is an effective method for diagnosing mass lesions in the chest, abdomen, pelvis, and paraspinal regions.
CT enhances procedural safety and diagnostic yield by optimizing needle trajectory and sample acquisition.
