PURPOSE In this imaging study, the radial displacement of meniscal allograft transplants (MATs), inserted with 2 different techniques, namely open soft-tissue fixation and arthroscopic bone tunnel fixation, was compared 1 year postoperatively. METHODS In this study, 37 patients received MATs: 16 MATs (10 lateral and 6 medial) were inserted by an open(More)
Long-term data on the clinical outcome and the fate of the meniscus allograft after transplantation are scarce. In this study we present the clinical, radiological and MRI outcome of the meniscus graft and the articular cartilage after 42 meniscus allograft transplantations in 41 patients with a minimum follow-up of 10 years. A total of 27 medial and 15(More)
PURPOSE To determine the prevalence of clinically relevant non-inflammatory disease on MRI of the sacroiliac (SI) joints in patients suspected of sacroiliitis. To assess the added value of axial imaging of the pelvis in these patients. METHODS In a retrospective study of 691 patients undergoing MRI of the SI joints from January 2006 to December 2012 for(More)
The purpose of this article is to review the basic principles and clinical applications of dynamic contrast-enhanced MRI in the musculoskeletal system. This method of physiologic imaging provides clinically useful information by depicting tissue vascularization and perfusion, capillary permeability, and composition of the interstitial space.

PURPOSE To evaluate the significance of dynamic contrast enhanced MRI (DCE-MRI) and whole body MRI (WB-MRI) in the diagnosis, prognosis and assessment of therapy for patients with monoclonal gammopathy of undetermined significance (MGUS) and multiple myeloma (MM). MATERIALS AND METHODS The retrospective study includes 219 patients providing 463 WB-MRI and(More)
PURPOSE To evaluate the value of the combined evaluation of SE MRI, dynamic contrast enhanced MRI (DCE-MRI) and diffusion weighted imaging (DWI) in multiple myeloma (MM) patients after treatment compared to the international myeloma working group (IMWG) response criteria. MATERIALS AND METHODS The retrospective study includes 27 newly diagnosed patients,(More)
The authors report the case of a 13-year-old patient with neurofibromatosis (NF-I), who suffered blunt trauma to the left tibia in 1993. The diagnosis of subperiosteal hematoma was made. Treatment consisted of temporary rest. There was a recurrence in 1996, and the subperiosteal hematoma was drained. In 1997, a shortening osteotomy of the left tibia was(More)
BACKGROUND Little is known about radial displacement (RD) of polyurethane (PU) scaffolds, intended for partial meniscus defect substitution; no data are available on whether rim thickness influences RD and whether RD correlates with clinical outcome scores. HYPOTHESES The meniscus is not extruded preoperatively, but RD occurs after scaffold implantation.(More)
The aim of this study was to investigate the combined effects of liquid crystal display (LCD) resolution, image magnification and window/level adjustment on the low-contrast performance in soft-copy image interpretation in digital radiography and digital mammography. In addition, the effect of a new LCD noise reduction mechanism on the low-contrast(More)
We modified the Hawkins impingement maneuver in order to develop a quantifiable and reproducible impingement test. The involved anatomic structures were examined with magnetic resonance imaging of 3 cadaveric shoulders. The reproducibility of the clinical sign was assessed with an interobserver and intraobserver reliability test, with calculation of the(More)
