Recommendations for acquisition and interpretation of MRI of the spine and sacroiliac joints in the diagnosis of axial spondyloarthritis in the UK.

Objectives: To develop evidence-based recommendations on the use of MRI in the diagnosis of axial SpA (axSpA).

Methods: A working group comprising nine rheumatologists and nine musculoskeletal radiologists with an interest in axSpA was established, with support from the British Society of Spondyloarthritis (BRITSpA). Two meetings were held.

Test-retest reliability of automated whole body and compartmental muscle volume measurements on a wide bore 3T MR system.

Purpose: To measure the test-retest reproducibility of an automated system for quantifying whole body and compartmental muscle volumes using wide bore 3 T MRI.

Materials And Methods: Thirty volunteers stratified by body mass index underwent whole body 3 T MRI, two-point Dixon sequences, on two separate occasions. Water-fat separation was performed, with automated segmentation of whole body, torso, upper and lower leg volumes, and manually segmented lower leg muscle volumes.

Imaging appearances and clinical outcome following sacrectomy and ilio-lumbar reconstruction for sacral neoplasia.

Objective: Sacrectomy and ilio-lumbar reconstruction is an uncommonly performed complex surgical procedure for the treatment of sacral neoplasia. There are many challenges in the post-operative period including the potential for tumor recurrence, infection, and construct failure. We present our experience of this patient cohort and describe the complications and imaging appearances that can be encountered during the follow-up period.

Imaging Metal-on-Metal Hip Replacements: the Norwich Experience.

Background: Adverse reaction to metal debris is a relatively recently described and often a silent complication of metal-on-metal (MOM) total hip replacements (THR). The Norfolk & Norwich University Hospital has been performing metal artefact reduction (MARS) MRI for 8 years in a variety of different types of MOM THR.

Questions/purposes: The aims of this review are to describe the experience of using MARS MRI in Norwich and to compare our experience with that published by other groups.

Detention and the evolving threat of tuberculosis: evidence, ethics, and law.

The issue of detention as a public health control measure has attracted attention recently. This is because the threat of strains of tuberculosis that are resistant to a wider range of drugs has been identified, and there is renewed concern that public health is threatened. This paper considers whether involuntary detention is justified where voluntary measures have failed or where a patient poses a danger, albeit uncertain, to the public.
