Bone biopsies are used to diagnose cancer that may have spread to the bone or is already in the bone. For accurate cancer diagnoses, interventional radiology (IR) bone biopsies are best done under the guidance of computed tomography (CT) imaging. The equipment required for CT during this procedure includes a gantry, table, and operator console. IR supplies all the needles, sterile drapes, and CT Localization grid. Bone biopsies require the use of a variety of needles to plan the procedure and collect a cell sample for analysis. The benefits of this procedure include a brief recovery, a less invasive procedure, and only requires the use of a local anesthetic. The risk of infection associated with CT-guided bone biopsies occurs less than one in a thousand. Compared to blind bone biopsies, CT-guided biopsies provide an accurate diagnosis about ninety percent of the time. Blind bone biopsies are unable to account for anatomical differences between patients. Studies found that CT-guided biopsies are better for inserting the needle in the correct spot because CT allows for visualization of the field.
