CT Scan Guided Procedure
A CT Scan–Guided Procedure is a minimally invasive technique where real-time CT imaging is used to accurately guide needles, catheters, or medical instruments to a specific target inside the body. This advanced method allows doctors to reach deep or small structures with high precision, reducing risks and improving diagnostic accuracy.
Why CT Guidance is Used
CT imaging provides detailed cross-sectional images, helping doctors:
Locate the exact position of abnormal tissue
Avoid vital organs and blood vessels
Ensure precise needle placement
Monitor the procedure in real time
This improves safety and accuracy compared to blind or conventional methods.
Common CT-Guided Procedures
Biopsies (lungs, liver, abdomen, lymph nodes, spine, etc.)
Abscess drainage and removal of fluid collections
Nerve blocks and pain management injections
Radiofrequency ablation and other targeted treatments
Needle aspiration of deep lesions
Localization of tumors before surgery
Procedure Overview
The patient is positioned on the CT table.
The area is cleaned and local anesthesia is applied.
CT images are taken to identify the exact entry point.
The doctor inserts the needle/instrument while monitoring CT images.
Once the target is reached, the biopsy, drainage, or treatment is performed.
A final CT scan confirms successful placement and completion.
