CT Guided Biopsy
Cat Scan guided biopsy provides the ability to offer image guided biopsies into certain nodules or cysts.
Using a sterile technique with CAT Scan guidance, a nodule can be further evaluated. A sample (s) of the nodule will be obtained when the nodule is solid or, in the case of a fluid filled cyst, fluid will be extracted from the nodule.
The area will be anesthetized and a needle will be inserted through the skin into the area of concern. Multiple samples of the nodule will be taken and sent to a laboratory for analysis. If the nodule is fluid filled, the fluid will be drained and a sample will be sent to a laboratory for analysis.
Image guided biopsy offers the opportunity for a less invasive procedure from surgery with diagnostic results
How to prepare for a CT Biopsy
- You will be asked to change into a gown for the procedure.
- You will be asked to stop eating or drinking four hours prior to the exam except for medications unless told otherwise.
- Before a CT biopsy, DRA Imaging's surgical nurse will contact you and review the procedure with you, as well as verify your medical history and any medications you are currently taking. If you are on any blood thinners such as coumadin or heparin, ibuprofen, or aspirin therapy, you will be asked to stop taking the regimen five days prior to the exam.
- Inform your doctor about any recent illness or other medical condition.
- You may want to have a friend accompany you to drive you home afterward.
What Happens during a CT Guided Biopsy
- You'll be placed on a CT examination table, usually lying flat on your back or sometimes on your side. Because movement can interfere with obtaining a clear image, straps and pillows are sometimes used to help you maintain the correct position and remain still.
- During the scanning itself, the table will move to its starting position and then move through the opening in the machine for the CT scanning.
The CT will show the exact location where a radiologist or physician's assistant will insert a needle to obtain a sample.
Once the area has been localized and anesthetized, multiple samples of the nodule will be taken and sent to a laboratory for analysis. If the nodule is fluid filled, the fluid will be drained and a sample will be sent to a laboratory for analysis. This procedure can last approximately 2 hours. The actual exam is usually about 30 minutes in length.
Pregnancy Policy:
All patients of childbearing age (10 - 54) will be required to sign that there is No Chance of Pregnancy prior to an imaging exam being performed (Exception: - Ultrasound). If there is a chance of pregnancy, STAT blood work will be ordered prior to the procedure being performed to establish that there is no chance of pregnancy.
In the event, you are pregnant and the exam is deemed necessary by your physician, you will be shielded and monitored with a radiation badge.
