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)
The use of 3T magnetic resonance imaging (MRI) of the clavicle in forensic bone age determination was prospectively examined and compared with plain radiography. Four MRI sequences and three radiographs of 121 healthy subjects between 11 and 30 were studied by two observers. The number of images assessable for bone age determination was lower for plain(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. Different(More)
PURPOSE To prospectively analyze the value of fast, dynamic, subtraction magnetic resonance (MR) imaging in the characterization of musculoskeletal tumors. MATERIALS AND METHODS In 175 consecutive patients with a musculoskeletal mass, dynamic contrast-enhanced subtraction MR imaging was performed after administration of 0.1 mmol per kilogram of body(More)
OBJECTIVE This study analyzed the value of dynamic contrast-enhanced and subtraction MR images in detecting residual viable tumor before surgery, with emphasis on timing of enhancement, in patients with high-grade osteosarcoma and Ewing's sarcoma after neoadjuvant chemotherapy. SUBJECTS AND METHODS Twenty-one patients with proved osteosarcoma or Ewing's(More)
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)
PURPOSE To assess the diagnostic value of parametric magnetic resonance images that display the first pass (FP) of gadopentetate dimeglumine. MATERIALS AND METHODS Dynamic, contrast material-enhanced, fast low-angle shot MR imaging was performed of 100 musculoskeletal lesions in 36 female and 64 male patients (aged 9-81 years [mean, 34 years]). The(More)
The development of the sternal extremity of the clavicle was examined prospectively with magnetic resonance imaging (MRI) for forensic bone age assessment. The objectives were to examine whether these results were comparable with the literature on plain radiography and CT, to provide age prediction intervals that correctly reflect the high variability in(More)
The purposes of this study were to evaluate the reliability and validity of ultrasound (US) for measuring the cross-sectional area (CSA) of the longus colli (LC) as compared with magnetic resonance imaging (MRI), and to determine the change in CSA of the LC during contraction. 27 healthy volunteers participated in the study. In order to assess the validity(More)
Magnetic resonance imaging is an important modality for the imaging evaluation of musculoskeletal tumors. Although there is general agreement on the value of unenhanced MR in detection, diagnosis and staging, intravenous use of gadolinium-contrast media (gd-CM) is indicated in selected cases. The purpose of this article is to review the basic(More)
