Imaging of total hip arthroplasty: part II – imaging of component dislocation, loosening, infection, and soft tissue injury
Despite the remarkable success of total hip arthroplasty as treatment of arthritis of the hip, complications can still occur, and imaging plays a crucial role for both diagnosis and guiding management. Component dislocation in total hip arthroplasty is usually diagnosed on radiographs, but cross-sectional imaging is necessary to quantitatively assess component orientation which may have predisposed to the dislocation. The definitive sign of component loosening on radiography is progressive motion of the component, but CT will provide more osseous detail and recent studies have shown the role of MRI in assessing component l...

Brain MRI and clinical exam findings in women with multiple gadolinium-based contrast agent (GBCA) exposures due to screening breast MRIs
Multiple exposures to gadolinium-based contrast agents (GBCAs) is known to be associated with gadolinium deposition in the brain in certain patients. Such deposition has been correlated with specific brain MRI findings, although most available data is in patients with underlying neurologic disorders. We aim to prospectively evaluate brain MRI signal changes as well as neurologic and neuropsychologic testing results in women undergoing screening breast MRI. (Source: Clinical Imaging)

Inter-transducer variability of ultrasound image quality in obese adults: Qualitative and quantitative comparisons
Acquiring high-quality ultrasound images of deep abdominal organs and vasculatures in obese adults (BMI>30  kg/cm2) is considered challenging. The aim of the study was to assess the inter-transducer variability in B-mode and color Doppler image quality from four commercial ultrasound transducers through qualitative and quantitative analyses.

Imaging characteristics of Sj ögren's syndrome
The current workup of Sj ögren's syndrome is based on diagnostic criteria involving a combination of histology, immunology, ophthalmology, and salivary flow. Several modern imaging techniques provide complementary and additional information to diagnosis, staging, and surveillance. In this review article, we discuss the cha racteristic salivary imaging findings seen with the most commonly utilized imaging modalities. We also discuss imaging findings of the central nervous system disorders associated with Sjögren's syndrome, including the neuromyelitis optica spectrum disorder, and provide a differential diagnosis of a lte...
