The incidence of skeletal TB is increasing. A better understanding of the MRI features of proven TB spondylitis in our setting is needed.Materials and methods. Histologically proven cases of TB spondylitis, with MR imaging performed at Universitas Hospital on a 1.5T scanner, were reviewed.Results. Typical findings of vertebral column involvement were seen in all patients, namely multiple levels affected and paravertebral abscesses.The thoracic spine was involved more than the lumbar spine. In nearly all cases intervertebral disc involvement was noted. Posterior longitudinal ligaments were intact in all but 1 patient, even though there was some elevation in a number of patients. Abscess walls were also found to be thick instead of thin as expected.

An increasing number of patients with metal implants are being referred for magnetic resonance imaging (MRI) investigations. Implants and devices may be divided into two groups, namely active and passive. This article will focus on passive devices. A device is MR-safe when it is used in the MR environment, but presents no additional risk to the patient or other individuals, although the quality of diagnostic information may be affected. MR procedures may be contraindicated due to various interactions between the MR environment and medical devices, which include torque, translational force, heating, induced electrical currents, magnetic field interactions, artefacts, and misrepresentation. Therefore, before deciding whether any object is MRsafe/ compatible, the intended use and the possible retaining mechanisms must be considered.
