Use of CT-guided percutaneous bone biopsy in staging of genitourinary tumors

CT-guided needle aspiration biopsy has been used for staging of genitourinary tumors. The display of structures provided by CT is particularly suited for complex anatomic sites such as spine, pelvis, thorax, permitting selection of the shortest and safest route for the needle, away from the aorta, vena cava, and pleural surface. Another advantage of CT is its ability to detect soft tissue components of the tumors and the presence of central necrosis therefore targetting the biopsy toward the part of the lesion with the greatest diagnostic yield.
