Accuracy Of Soft Tissue Puncture Biopsy Needle

The accuracy rate of puncture biopsy needle is about 90%. Puncture biopsy needle is mostly carried out by fine needle puncture under the guidance of ultrasound, and a small amount of tissue in the biopsy tissue is extracted for pathological observation. There are many influencing factors, including the possibility of false (+) and false (-). First of all, it is related to the technique of the piercer. The amount of tissue extracted from the puncture is usually relatively small. In the process of pathological pictures and pathological examination, the tissue may be too few to reach an accurate pathological conclusion.
