Biopsy
Interventional radiology is a minimally invasive field that uses medical imaging techniques for the diagnosis and treatment of diseases. Interventional radiological biopsy is a procedure used to obtain tissue samples for disease diagnosis. Using methods such as ultrasound, computed tomography (CT), or magnetic resonance imaging (MRI), a small needle is inserted into the targeted area to collect samples, eliminating the need for surgical intervention.
Treatment Process with Biopsy and Interventional Radiology
A biopsy is a procedure in which a sample is taken from any tissue, organ, or lesion in the body to examine its cellular structure. This procedure plays a crucial role in diagnosing conditions such as cancer, infections, inflammations, and other abnormalities. Interventional radiology is a field that performs biopsies using minimally invasive methods, prioritizing patient safety and comfort without the need for surgical intervention.
What is a Biopsy and Why is it Done?
A biopsy is a procedure performed to determine the diagnosis and treatment process of abnormal structures in the body. A small tissue sample is taken for pathological examination. Biopsy is typically performed in the following situations:
Suspicion of Cancer: Tumors, nodules, or lesions found in the body are examined with a biopsy to determine if they are cancerous.
Infections and Inflammations: If there are significant inflammatory conditions or infections in the body, a biopsy helps identify the type and spread of the infection.
Monitoring Diseases: Biopsy can be repeated to track the progression of diseases and the response to treatment.
Hormonal Imbalances: Abnormal growths or tissue changes in the body may indicate hormonal imbalances.
Abnormalities in Internal Organs (such as the liver, kidneys, or lungs): Tissue samples are taken to investigate potential diseases in these organs.
Biopsy Methods with Interventional Radiology
Interventional radiology performs biopsy procedures under imaging guidance, which increases the accuracy of the procedure and reduces risks for patients. Some of the biopsy methods used in interventional radiology include:
Ultrasound-Guided Biopsy:
-
How it’s done: An ultrasound device is used to guide a needle to the targeted area, and a tissue sample is collected.
-
Advantages: The accuracy of the procedure is high due to precise targeting. It is commonly used for areas such as the liver, kidneys, and thyroid.
Computed Tomography (CT)-Guided Biopsy:
-
How it’s done: During a CT scan, images are used to guide a needle into the lesion. After confirming the needle's position with control images, the sample is taken.
-
Advantages: This method ensures high accuracy in targeting the area. It allows biopsies to be performed in deep or hard-to-reach areas, such as the lungs or pancreas.
How is a Biopsy Performed?
-
Preparation:
-
Local anesthesia is applied to the area where the biopsy will be performed, ensuring no pain during the procedure.
-
Procedure:
-
The interventional radiologist uses the appropriate imaging technique to locate the target area and takes a tissue sample with a biopsy needle.
-
The procedure typically lasts between 10 to 30 minutes, and most patients do not require hospitalization.
-
After the Procedure:
-
Patients are monitored briefly after the procedure. Pain is usually minimal, and most patients can be discharged on the same day.
-
The collected tissue sample is sent to the laboratory for pathological examination. Results are typically available within a few days.
Advantages of Biopsy
-
Minimal Invasiveness:
-
Tissue samples are obtained with a small needle, without the need for large surgical incisions.
-
Quick Recovery:
-
The recovery time is short, and pain levels are generally low after the procedure.
-
High Accuracy:
-
The use of imaging techniques ensures that the biopsy is performed accurately and safely.
-
Rapid Diagnosis:
-
It's a crucial step for the early detection of cancer and other diseases, enabling timely treatment.
Things to Consider After Biopsy
-
Post-Procedure Care:
-
Generally, no special care is required after the procedure.
-
Pain Management:
-
Mild pain or tenderness is normal. Pain relievers recommended by your doctor can be used to manage discomfort.
-
Bleeding and Infection Risk:
-
If you notice signs of bleeding or infection (e.g., redness, swelling), contact your doctor immediately.
-
Follow-Up Appointments:
-
It's important to follow up with your doctor for evaluation of results and ongoing monitoring.
