CT-guided procedure, also known as CT-guided intervention or CT-guided intervention, is a minimally invasive medical procedure that uses computed tomography (CT) imaging to guide the placement of instruments or devices to perform various medical interventions or treatments. CT is a type of imaging technique that uses X-rays and a computer to create detailed cross-sectional images of the body, allowing physicians to visualize internal structures and guide their interventions with precision.

CT-guided procedures are commonly used in various medical specialties, including radiology, interventional radiology, pain management, oncology, and cardiology. Some examples of CT-guided procedures include:

1. Biopsy: CT-guided biopsies are performed to obtain tissue samples from suspicious masses or lesions for further diagnostic evaluation. The CT images help guide the placement of a needle or other instruments to precisely target the area of interest for sampling.

2. Drainage procedures: CT-guided drainage procedures are used to remove fluid collections or abscesses from the body, such as in the chest, abdomen, or pelvis. CT imaging helps to accurately locate the fluid collection and guide the placement of a catheter or drain to drain the fluid.

3. Pain management procedures: CT-guided nerve blocks or injections are used to relieve pain in various parts of the body, such as the spine, joints, or nerves. CT imaging helps to accurately target the specific area for the injection to provide pain relief.

4. Tumor ablation: CT-guided tumor ablation is a minimally invasive treatment for tumors, such as liver tumors or lung tumors. It involves using a needle or probe guided by CT imaging to deliver energy, such as heat or cold, to destroy the tumor tissue.

5. Vascular interventions: CT-guided vascular interventions, such as angiography or angioplasty, are used to diagnose and treat conditions affecting the blood vessels, such as blockages or narrowing. CT imaging helps visualize the blood vessels and guide the placement of catheters, stents, or other devices for treatment.

CT-guided procedures are generally considered safe and effective, with minimal risks and complications. However, as with any medical procedure, there may be some risks, such as bleeding, infection, or damage to surrounding structures. The specific risks and benefits of a CT-guided procedure depend on the type of procedure, the location of the intervention, and the patient’s overall health condition. It is important to discuss the risks and benefits with a qualified healthcare provider before undergoing any medical procedure.
