Interventional Biopsy
Last Updated: August 2026
A biopsy procedure involves removing a small sample of tissue or fluid from the body so it can be examined to help detect, stage, or monitor disease. In interventional radiology, imaging-guided interventional biopsy refers to using ultrasound, CT, or fluoroscopy to precisely guide a needle to the area of concern to obtain a sample safely and accurately. These techniques are commonly used to investigate abnormalities, confirm or refine a diagnosis, plan treatment, and track response to therapy. Because most biopsy procedures are performed with a needle through the skin, they usually involve lower risk, quicker recovery, and less discomfort than open surgical methods.
During an ultrasound guided biopsy–or with guidance from CT or MRI–a specially trained physician uses real-time imaging to direct a thin needle precisely to the area of concern to obtain tissue or fluid. Depending on what is needed, the doctor may perform a fine needle aspiration biopsy to collect cells, use a core needle biopsy to remove a small cylinder of tissue, or employ a vacuum-assisted device to gather larger or multiple samples through a single insertion. In select cases, image guidance is used to direct an endoscopic or laparoscopic tool for sampling when percutaneous access is not suitable.
The collected specimens are analyzed by a pathologist to determine whether the abnormality represents inflammation, infection, benign change, precancerous change, or cancer, and to identify specific features such as tumor type, grade, and molecular markers that can guide therapy. Multiple samples may be obtained to ensure accuracy and to perform additional tests such as cultures for infection or genetic and receptor profiling.
Interventional biopsy services are used across many organ systems, including breast, lung, liver, kidney, lymph nodes, thyroid, bone and soft tissue, prostate, and abdominal or pelvic masses. They are also used to sample fluid collections (such as cysts or abscesses), evaluate transplant organs, and confirm recurrence or response after treatment. In some cases, the same session can include therapeutic steps–such as draining fluid, placing a catheter, or delivering targeted therapy–based on the biopsy findings. The expanding capabilities of image-guided techniques help your care team make timely, precise decisions tailored to your condition.
Biopsy Recovery
After the procedure, a small bandage is placed over the site, and you’ll be monitored briefly before going home. Minor soreness or bruising at the entry point is common and usually improves within 24-72 hours. Keep the area clean and dry for the first day, avoid heavy lifting or vigorous exercise for 24-48 hours (longer for lung, kidney, or bone biopsies), and follow any site-specific instructions your team provides. Call your provider if you experience increasing pain, fever, redness, drainage, shortness of breath, or bleeding that does not stop with gentle pressure.
