How effective is percutaneous needle biopsy?
Percutaneous biopsy is a very effective procedure with high diagnostic yield. Low false-positive and false-negative results are achieved in most organs. The success of IPNB is affected by multiple variables, including the number of samples obtained, the size and location of the target lesion, the type of needle used, the availability of an on-site cytologist, and the experience of the performing physician and the pathology staff. The reported overall success rate of IPNB ranges between 70% and 96% among all organs.
