摘要

Frame-based stereotactic systems have provided the gold-standard method of needle guidance for tumor biopsy, aspiration of fluid masses and catheter placement. To overcome some of the disadvantages of conventional stereotaxy, frameless stereotactic systems are being used with increasing frequency for performing stereotactic needle guided procedures. In this paper Authors report a personal series of 115 needle guided procedures, 65 performed with conventional stereotactic frame and 50 accomplished with frameless image-guided system (IGS), in order to compare the clinical accuracy and evaluate advantages and limits of both technologies. This comparison study demonstrates that frameless stereotaxy brings with it tangible advantages while maintaining the same accuracy of standard frame-based method.
