A useful technique for computerized tomography directed needle biopsy.
This technique uses a simple, inexpensive device to facilitate a previously proved method of obtaining cytologic specimens with a Chiba needle under CT guidance. The plastic sheath could be scored with metric markings and would further facilitate its use as a depth gauge. This method obviates the need for multiple scans required to place the needle at the appropriate depth, thereby decreasing the length of the procedure and unnecessary radiation to the patient.
