Background: Woakes' disease is the eponymous name for severe chronic rhinosinusitis with nasal polyposis (CRSwNP) leading to thinning and expansion of the nasal pyramid. The endoscopic treatment of the sinus disease, while extensive, is standard practice for the rhinologist. Management of their external nasal deformities, for many, is not.

Department of Surgery, St Joseph's Hospital, Roth-McFarlane Hand and Upper Limb Center, St Joseph's Hospital London, Ontario, Canada. Electronic address:

Purpose: Total elbow arthroplasty (TEA) is increasingly used for the management of comminuted distal humeral fractures in elderly patients. There are limited data on the outcome of modern elbow arthroplasty designs in larger patient cohorts. The aim of the current study was to review the outcomes and complications using a cemented convertible TEA system in a linked configuration in patients with distal humeral fractures.

Technical Note: Evaluation of a 160-mm/256-row CT scanner for whole-heart quantitative myocardial perfusion imaging.

Imaging Program, Lawson Health Research Institute, London, Ontario N6A 4V2, Canada and Imaging Research Laboratories, Robarts Research Institute, London, Ontario N6A 5K8, Canada.

Purpose: The authors investigated the performance of a recently introduced 160-mm/256-row CT system for low dose quantitative myocardial perfusion (MP) imaging of the whole heart. This platform is equipped with a gantry capable of rotating at 280 ms per full cycle, a second generation of adaptive statistical iterative reconstruction (ASiR-V) to correct for image noise arising from low tube voltage potential/tube current dynamic scanning, and image reconstruction algorithms to tackle beam-hardening, cone-beam, and partial-scan effects.

Methods: Phantom studies were performed to investigate the effectiveness of image noise and artifact reduction with a GE Healthcare Revolution CT system for three acquisition protocols used in quantitative CT MP imaging: 100, 120, and 140 kVp/25 mAs.

Mechanical low back pain is a common indication for Nuclear Medicine imaging. Whole-body bone scan is a very sensitive but poorly specific study for the detection of metabolic bone abnormalities. The accurate localisation of metabolically active bone disease is often difficult in 2D imaging but single photon emission computed tomography/computed tomography (SPECT/CT) allows accurate diagnosis and anatomic localisation of osteoblastic and osteolytic lesions in 3D imaging.
