New techniques in image-guided percutaneous biopsy

Image-guided percutaneous biopsy is a well-established and safe technique for obtaining tissue specimens from various regions of the body and plays a crucial role in patient management. Improvements in needle designs, development of new biopsy techniques, and continual advances in image-guidance technology have improved the safety and efficacy of the procedure. Lesions previously considered relatively inaccessible can now be safely biopsied. This review looks at the recent technologic developments in image guidance for percutaneous biopsy procedures. Improvements in needle design and other innovations intended to enhance the diagnostic yield of biopsy specimens are briefly discussed. Also described are some new techniques and unconventional approaches that help provide safe access to difficult-to-reach lesions.
