“…4 Similarly, in a nontrauma setting, especially oncology patients and patients with pyrexia of unknown origin, spinal reconstructions are routinely performed to assist in the detection of bone, paravertebral, and disc pathologies. 20 Image noise levels were significantly higher for reconstructed lumbar spine images from CTAP compared with L-spine CT, when both were reconstructed using SIR. As a result, the interfaces between bone, disc, CSF, and soft tissues were less well defined in the reconstructed spinal images from CTAP ( Figure 2) due to increased image noise, making detection of subtle fractures and disc pathology more difficult.…”

Objective: We sought to compare the image quality of iterative model reconstruction (IMR) with statistical iterative reconstruction (SIR) in lumbar spine (L-spine) images reconstructed from computed tomography (CT) image data from examinations of the abdomen and pelvis compared with routine L-spine CT images reconstructed with SIR. Methods: We conducted a retrospective study to compare image noise in L-spine reconstructions using SIR and IMR techniques in consecutive CT abdomen and pelvis (CTAP) examinations, with L-spine CT images reconstructed using SIR. Hounsfield units and their standard deviations in areas of image noise were measured in bone, cerebrospinal fluid (CSF), and lumbar discs. The results of SIR and IMR were compared using paired t tests. The results of CTAP and CT L-spine were compared using the Mann-Whitney U test. A p value <0.05 was considered significant. Qualitative assessment of the bone/CSF, disc/CSF, and disc/bone interface was performed by two readers. Results: IMR generated less image noise than SIR with CTAP and L-spine CT with SIR, particularly on bone windows. There was also significant improvement in the clarity of interfaces between vertebral bodies, discs, epidural fat, and CSF with IMR. The mean radiation dose was much higher for L-spine CT compared with CTAP. Conclusion: IMR is superior to SIR for the image quality of reconstructed lumbar spine images from CTAP. The IMR lumbar spine image from CTAP image data acquired with a lower radiation dose was also shown to be clearer when compared with routine SIR L-spine CT images.

“…The organism spreads hematogenously to the spine, lodging in end vessels usually anteriorly in the vertebral body, beneath the endplate (6). Chest X-rays can be the first imaging tip-off to spinal infection, when the thoracic spine is involved.…”

“…These infections are typically due to bacterial organisms, and significant risk factors include diabetes, autoimmune diseases, malignancy, immunosuppression, and intravenous drug use (75). Early multidetector CT findings include paravertebral fat infiltration and intervertebral disk hypoattenuation, whereas osseous erosion, disk space narrowing, and sequestrum formation may be present in later stages (75) (Fig 20). In the setting of immunodeficiency, particularly human immunodeficiency virus (HIV) infection, tuberculous involvement of the spine should be considered.…”
