What is a CT Guided Injection?
A CT-guided injection is a medical procedure in which imaging from a computed tomography (CT) scanner is used to guide the precise placement of a needle to deliver medication or perform diagnostic tests. This procedure is often used to treat or diagnose pain, inflammation, or other conditions in hard-to-reach areas.
What conditions are treated with CT guided injections?
These are commonly used to treat pain related to conditions such as arthritis, herniated discs, and inflammation of joints, tendons, or bursae. They can also be used for diagnostic purposes such as pinpointing the source of pain or to deliver chemotherapy directly to tumors.
How should I prepare for a CT guided injection?
Preparation typically involves fasting for a few hours before the procedure if sedation is to be used. Patients should inform their doctor about all medications they are taking and any allergies, especially to contrast material. Wearing comfortable, loose-fitting clothing is recommended.
Are CT guided injections painful?
Patients usually feel a pinch or sting when the local anesthetic is injected, but this injection itself is generally not painful. Some discomfort might be felt when the medication is injected, depending on the area being treated.
What are the risks of CT guided injections?
The risks are relatively low but can include bleeding, infection at the injection site, allergic reaction to the contrast dye, and injury to nearby nerves or structures. However, the use of CT guidance significantly reduces these risks.
How long does the procedure take?
The entire procedure usually takes about 30 minutes. The actual injection takes only a few minutes, but preparation and positioning may take additional time.
What is the recovery time after a CT guided injection?
Most patients can leave our clinic shortly after the procedure. Recovery typically involves limited activity for a day or so, and patients are advised to have someone drive them home. The full effects of the medication may take a few days to become apparent.
