CT Guided Lung Biopsy Procedure: Step-by-Step Approach
A CT guided lung biopsy is a detailed procedure for diagnosing lung issues. It involves a careful, step-by-step method to get accurate tissue samples. This is key for finding out what’s wrong and how to treat it.
Initial CT Scan for Lesion Localization
The first step is to do a CT scan to find the lung lesion. This scan shows where, how big, and how deep the lesion is. This info is vital for planning the biopsy.
Key considerations during the initial CT scan include:
- Patient positioning to optimize access to the lesion
- Adjusting CT scanner settings for optimal image quality
- Identifying any anatomical structures that may interfere with the biopsy needle trajectory
Entry Site Selection and Marking
After finding the lesion, the next step is to pick and mark the entry site on the skin. This involves:
- Using the CT scan images to determine the optimal entry point
- Marking the skin with a suitable marker or dye
- Ensuring the entry site is clean and prepared for the procedure
Local Anesthesia Administration
To make the patient more comfortable, local anesthesia is given at the entry site. The type of anesthetic and how it’s given can change based on the patient and the doctor’s choice.
| Anesthetic Type | Administration Technique | Effectiveness |
| Lidocaine | Subcutaneous injection | High |
| Procaine | Infiltration anesthesia | Moderate |
Needle Insertion Technique
The last step is to put the biopsy needle into the lung lesion under CT guidance. This needs precision and careful handling to avoid problems.
Critical aspects of the needle insertion technique include:
- Using real-time CT imaging to guide the needle
- Adjusting the needle trajectory as needed
- Monitoring for possible complications, such as pneumothorax
By following these steps, doctors can make sure the CT guided lung biopsy is safe and works well.
Tissue Sampling Techniques
Tissue sampling techniques are key in finding out what’s wrong during CT guided lung biopsies. The method used can greatly affect how accurate the results are.
Fine Needle Aspiration (FNA)
Fine Needle Aspiration (FNA) is a common method used in CT guided lung biopsies. It uses a thin needle to take cells from lung lesions. FNA is great for getting samples from hard-to-reach or sensitive areas. The National Cancer Institute says FNA is very good at diagnosing lung issues.
“FNA is a valuable tool in the diagnosis of lung lesions, providing a minimally invasive approach with high diagnostic yield.”
National Cancer Institute
Core Needle Biopsy
Core Needle Biopsy is another technique used in CT guided lung biopsies. It uses a bigger needle to get a chunk of tissue from the lesion. Core Needle Biopsy gives a bigger sample than FNA, which helps in diagnosing some lung issues. Whether to use FNA or Core Needle Biopsy depends on the lesion’s size, location, and the patient’s health.
Multiple Sampling Strategies
In some cases, using more than one sampling method is needed to get accurate results. This might mean using both FNA and Core Needle Biopsy. Using multiple methods can help get a clearer picture of the lung issue.
- FNA for cytological examination
- Core Needle Biopsy for histological examination
Specimen Handling and Preservation
It’s very important to handle and preserve the samples correctly to get accurate results. Specimens from CT guided lung biopsies need to be handled carefully to avoid damage. They should be kept in the right fixative and sent to the lab quickly.
