Soft Tissue Deep Biopsy (Computed Tomography-Guided)
This procedure involves removing a small sample of tissue from deeper layers of your body using a needle guided by a CT scan to help diagnose conditions like tumors, infections, or inflammatory diseases.

Why This Test Is Done
Your doctor may recommend this test if they suspect a condition such as a tumor, infection, or chronic inflammation in deep soft tissues (e.g., muscles, fat, or connective tissue). Common reasons include unexplained lumps, persistent pain, or abnormal findings on imaging studies like MRI or ultrasound.
How the Procedure Works
You’ll lie on your side or back while a CT scanner takes real-time images of the targeted area. A radiologist guides a needle through your skin and into the tissue using the CT scan for precision. A small sample of tissue is collected, which is then sent to a lab for analysis.
Preparation
You may be asked to fast for a few hours before the procedure, depending on your doctor’s instructions. Wear comfortable clothing and remove any jewelry or devices that could interfere with imaging. Inform your doctor about any medications you’re taking, especially blood thinners.
During the Procedure
You’ll receive local anesthesia to numb the area, so you may feel pressure but minimal pain. The procedure typically takes 30–60 minutes. You’ll be monitored closely for any reactions to anesthesia or complications.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
This biopsy provides critical information for diagnosing conditions like malignant tumors (cancer), benign growths, infections (e.g., abscesses), or autoimmune-related tissue changes. Results help guide treatment plans, such as surgery, further imaging, or targeted therapies.
