C-arm cone beam computed tomography needle path overlay for image-guided procedures of the spine and pelvis.

Introduction: The aim of this study is to report our early clinical experience using C-arm cone beam computed tomography with fluoroscopic overlay for image guidance during percutaneous needle procedures of the spine and pelvis.

Methods: Twelve consecutive patients (four female and eight male patients; mean age, 64 years; range, 47-74 years; SD ± 7.6 years) who underwent percutaneous biopsy of the spine and pelvis for suspected metastasis (n = 12), spondylodiscitis (n = 6), abscess (n = 5) or bone tumour (n = 1) were prospectively included between March 2009 and November 2010.
