The objective of this study was to use MR imaging to detect macrophage infiltration of the kidney after injection of ultrasmall superparamagnetic iron oxide (USPIO) particles in a rat model of experimental nephropathy. Ninety micromol of USPIO were injected intravenously in 10 rats with nephropathy secondary to intravenous injection of 5 mg of puromycin(More)
INTRODUCTION It has become well recognised that sagittal balance of the spine is the result of an interaction between the spine and the pelvis. Knee flexion is considered to be the last compensatory mechanism in case of sagittal imbalance, but only few studies have insisted on the relationship between spino-pelvic parameters and lower extremity parameters.(More)
PURPOSE The aim of this study is to compare the accuracy and reliability of spinal curvatures and vertebral rotation data based on patient-specific 3D models created by 3D imaging system or by bi-planar imaging coupled with Moiré-Fringe projections. METHODS AND MATERIALS Sixty-two consecutive patients from a single institution were prospectively included.(More)
BACKGROUND Ultrasound (US) is a good first-line alternative for the diagnosis of bone fractures in adults as well as children. Our study shows that, compared to X-ray, in a resource-constrained environment, on-site US has a high sensitivity (98%) and specificity (96%) in the diagnosis of bone fractures. PURPOSE To compare the accuracy of on-the-spot US(More)
Discography test associated with the scanner (discoscanner) is an exam that has been a renewed interest in recent few years. Thanks to the emergence of new interventions such as disc prosthesis, the procedures require confirmation of the disc level to deal with and the origin of discogenic symptoms. The aim of this paper is to describe the techniques,(More)
Transfacet screws may be useful for stabilizing segments reconstructed with bone graft or cages, the role of supplementary posterior fixation, particularly minimally invasive techniques such as transfacetar percutaneous screws is relevant. To benefit from a mechanical fixation after anterior arthrodesis without the inconveniences of the open classical(More)
OBJECTIVES The goals of this study is to evaluate and compare the irradiation received by the practitioner when performing percutaneous vertebroplasty or kyphoplasty guided by CT and fluoroscopy, for precise anatomical sites. METHODS For each intervention, radiothermoluminescent dosimeters were carefully positioned on both orbitals, both hands, and both(More)
