A CT guided biopsy is a procedure performed by a radiologist to obtain a small tissue sample using a needle. But, why is a CT guided biopsy done? The primary purpose is to obtain a tissue sample for diagnostic purposes, which then informs the planning of future medical management. A CT (Computed Tomography) scan is employed to guide the needle precisely into the lesion in the safest way possible. This technique represents a minimally invasive alternative to traditional open surgical biopsies.
CT guidance typically leads to fewer complications, a quicker recovery period, and the avoidance of general anesthesia, making it a preferred option in many scenarios. This method is especially useful when the area of interest is deep within the body or difficult to access through other means.
Patient Preparation for a CT Guided Biopsy
Proper preparation is crucial for a successful CT guided biopsy. Inform the clinic immediately at (352) 265-0875 or (352) 265-0116 if you are currently taking blood-thinning medications, such as Coumadin, or anti-diabetic medications like Glucophage (Metformin). These medications can affect bleeding and need to be managed carefully before the procedure.
Additionally, it’s essential to report any known contrast allergies to the same contact numbers. Patients are usually advised to have their last meal before midnight on the day of the procedure. If you take blood pressure medication, continue to take it as scheduled, but with only a small sip of water.
What to Expect During the Procedure
Upon arrival, you’ll be prepared in a holding area where you’ll change into a hospital gown, and an intravenous (IV) line will be inserted. Through the IV, you may receive sedation and pain medications to ensure you remain relaxed and comfortable throughout the procedure.
During the CT scan, the needle is carefully inserted into the lesion, and multiple biopsy samples are collected. The duration of a CT-guided biopsy averages between 45 minutes to an hour, but this can vary depending on the lesion’s location. Keep in mind that this time does not include preparation and recovery time in the holding area. The entire process might take several hours, so arranging for someone to drive you home is recommended.
Potential Complications
While CT guided biopsies are generally safe, understanding the potential complications is important. These risks include bleeding, nerve injury, infection, and allergic reactions to the contrast dye or medications used during the procedure. Healthcare professionals take every precaution to minimize these risks.
Aftercare Instructions
Pain following the procedure typically subsides within a few days. You can usually resume normal activities the day after the biopsy.
The tissue samples require processing to determine the diagnosis, and results are usually available from your primary physician within several days. Follow-up appointments and discussions about the results will help in planning your future medical care.
Consent Forms
Before undergoing a CT guided biopsy, patients are required to provide informed consent. Reviewing and signing the consent forms ensures you understand the procedure, its risks, and benefits. Your physician will review the entire process with you during your appointment, addressing any questions or concerns you may have.
Understanding why a CT guided biopsy is done, how to prepare for it, and what to expect can alleviate anxiety and ensure you are an active participant in your healthcare journey.
