The ultrasound is a very common test in the medical field in recent years. FNA, which means fine needle aspiration biopsy, is a minimally invasive procedure. FNA is a minimally invasive procedure that allows you to obtain samples such as tissue cells from the human body for cytological examination outside the body in order to confirm whether or not the tissue is abnormal.
The FNA technique in ultrasound is mainly used to biopsy abnormal tissues such as tumors. During the examination, the doctor will keep the patient in a relatively stable position. After finding the location to be examined, the doctor will use an appropriate fine needle to puncture and take a sample. Typically, the sample size for FNA sampling is relatively small, but a relatively representative sample of tissue can be taken.
Although the sample size of FNA technology is relatively small, the examination can determine the condition of a tumor or other disease in order to provide a reference for the patient to carry out the subsequent treatment plan. In addition, FNA sampling can also save patients' time and cost. Although FNA has its limitations and risks in ultrasound, it is still one of the safest and most effective ways to detect tumors.
