Needle biopsy is one of the most frequently performed procedures in daily interventional radiology practice. It is a diagnostic procedure. Almost all biopsies today, except for some special biopsies (brain, prostate, etc.) needle biopsy taken with. Needle biopsy involves taking a piece of the relevant tissue with a very thin needle, approximately 1 mm thick, accompanied by imaging. Here, ultrasound or tomography imaging is used. A biopsy is basically done to reveal whether an unusual mass observed in the body is cancer. Needle biopsy is used when taking parts from many different parts of our body such as thyroid, liver, kidney, breast, lung, head and neck. In addition, in cases with suspected bone tumor, biopsy can be taken from the mass in the bone with this method.

Thyroid nodules, salivary gland masses, lymph nodes, subcutaneous nodules, lung nodules, cirrhosis of the liver, cirrhosis onset, fatty liver, liver tumors, renal masses, breast tumors, bone tumors.
How is Needle Biopsy Performed?
An average of 4 hours of fasting is required before the procedure. Local anesthesia is applied to the area to be sampled. In other words, general anesthesia is not given to the patient. Sometimes the patient may also be given intravenous pain relievers. However, if our patient is a child, general anesthesia is preferred. The patient does not feel any pain during the biopsy. The procedure is performed in the interventional radiology unit, not in the operating room, and the patient does not need to be hospitalized. It is a daily operation. It can be applied to patients of all ages, children and pregnant women. Needle biopsy involves taking a piece of tissue by reaching the relevant tissue with imaging. First, the area to be entered is sterilized. A thin needle, approximately 1 mm in diameter, is then inserted into the tissue. The interventional radiologist performs the procedure by following it step-by-step on the monitor. As such, it is a very safe procedure. Finally, biopsy samples are taken from the relevant tissue and the needle is removed. It is checked whether there is any bleeding in the operation area. The process is terminated. The procedure is usually completed in 15 to 30 minutes, depending on factors such as the biopsy area, the mass from which the biopsy was taken, and the experience of the physician. After the procedure, we follow our patients in the daily hospitalization unit for about 3 hours. If all is well, we plan their discharge. Biopsy taken from the patient is studied in the laboratory. The definitive diagnosis of the disease is made in the light of the results. The treatment of the patient is planned.
