title: Computed tomography-guided percutaneous biopsy: a combined approach to the retroperitoneum.
abstract: When computed tomography (CT) is used to evaluate the lumbar spine in patients with low back pain, it is important to look at the adjacent retroperitoneum. CT is ideally suited to visualize the retroperitoneum and provide access for percutaneous needle biopsy.
