Update on MR Imaging of Hip Arthroplasty.

MR imaging of hip arthroplasty can be technically challenging due to artifacts associated with metallic implant components; however, utilization of specific parameter modifications and advanced metal reduction sequences allows acquisition of high-quality diagnostic images in patients with metallic implants. Given the increasing prevalence of hip arthroplasties within the population, familiarity with appropriate imaging techniques and expected pathology within this patient population is important knowledge for radiologists who encounter patients with hip arthroplasty in clinical practice.

Breathing techniques to reduce symptoms in people with serious respiratory illness: a systematic review.

Background: In adults with serious respiratory illness, breathlessness is prevalent and associated with reduced health-related quality of life. The aim of this review was to assess the impact of breathing techniques on breathlessness in adults with serious respiratory illness.

Methods: Electronic databases were searched to identify randomised controlled trials testing breathing techniques (techniques that aim to alter the respiratory pattern, excluding respiratory muscle training) in people with serious respiratory illness.

Utility of Zero Echo Time MRI for the Diagnosis and Characterization of Ankle Fractures.

Zero echo time (ZTE) imaging is a relatively new magnetic resonance (MR) pulse sequence that provides bone-soft tissue contrast similar to that of computed tomography (CT). We sought to (1) determine the accuracy of ZTE MRI for the diagnosis of common ankle fractures and (2) investigate whether ZTE imaging sequences are equivalent to the gold standard of CT for the characterization of fracture fragments. We conducted a prospective case series of 54 patients with acute ankle trauma, in whom ZTE MRI was performed, followed by surgical reduction.
