What Is a Biopsy, How Is It Performed?
A biopsy is the procedure most commonly performed in interventional radiology, carried out to determine whether a lesion is tumor, inflammatory or normal tissue.
A biopsy is generally one of the routine procedures of interventional radiology, although it may sometimes also be used in surgical applications. A biopsy is a technique used to take small tissue samples and send them to the laboratory for analysis.
It can be used to determine the type or condition of a tumor, to diagnose whether a tumor is benign or malignant, to determine how well a tumor will respond to treatment, or to evaluate the spread of a tumor. A biopsy may also be used in the diagnosis and treatment of inflammatory diseases or in the evaluation of normal tissues.
The procedure takes an average of 20 minutes. After liver and lung biopsies, patients are kept under observation for one hour and then discharged after clinical follow-up. Biopsy results are finalized within 2 business days at the latest (unless immunostaining or special procedures are required).
The day after the procedure, all daily activities can be resumed without restriction.
What Is a Fine Needle Biopsy, How Is It Performed?
Fine needle biopsy (FNB) is a sampling method used as a radiological technique to examine samples taken with a small needle. FNB is a technique used to detect small pathological changes, abnormal tissue or tumors in the body.
Beforehand, all data regarding the relevant anatomical area and disease are evaluated by the interventional radiologist, who decides which imaging device (ultrasound, computed tomography, magnetic resonance imaging, fluoroscopy, angiography) will be used.
The skin over the projected area of the biopsy site is cleaned with antiseptic solution, and local anesthesia is administered with a very fine needle. Subsequently, under imaging guidance, the needle is inserted into the lesion and cells are collected. The material is spread on a slide and sent to the pathology laboratory.
What Is a Core Needle Biopsy?
To diagnose certain diseases and perform tests, it may be necessary to take a tissue sample. The procedure begins in the same way as fine needle biopsy, and then, using special needles, a thin piece of tissue is taken from the lesion and sent to the pathology laboratory.
