MR imaging findings in early osteoarthritis of the knee
(2004)Purpose: To carry out a modern diagnostic survey among patients with a clinical and radiological diagnosis of early osteoarthritis of the knee. Materials and methods:A magnetic resonance imaging survey was performed on 70 ... -
Multifunctional Polymeric Platform of Magnetic Ferrite Colloidal Superparticles for Luminescence, Imaging, and Hyperthermia Applications
(2016)Adequately designed multiresponsive water-soluble graft copolymers were used to serve as a multifunctional polymeric platform for the encapsulation and transfer in aqueous media of hydrophobic magnetic nanoparticles (MNPs). ... -
A numerical model for aggregations formation and magnetic driving of spherical particles based on OpenFOAM®
(2017)Background and objective This work presents a numerical model for the formation of particle aggregations under the influence of a permanent constant magnetic field and their driving process under a gradient magnetic field, ... -
Osteonecrosis of the femoral head: Etiology, imaging and treatment
(2007)Osteonecrosis of the femoral head is a disabling clinical entity affecting young adults that usually leads to destruction of the hip joint. A high index of suspicion is necessary for the diagnosis due to the insidious onset ... -
Prediction of collapse of the osteonecrosis of the hip by determining location and size of the lesion: A 2 to 17 years study
(2010)Osteonecrosis of the femoral head is a disease responsible for a large number of arthroplasties in young and active patients in the western world. Prediction of outcome of the disease remains a difficult task. The purpose ... -
Prognosis of collapse of the osteonecrosis of the femoral head for patients treated with a tantalum rod by determining location and size of the lesion
(2009)The purpose of this study is to predict the osteonecrosis of the femoral head by examining the location and size of the lesion of the femoral head. A triangulation approximation algorithm is used for the computation of the ... -
Proton magnetic resonance spectroscopy at 3T - Evaluation of metabolic profile of human brain lesions
(2009)Brain MR imaging at 3T has been increasingly used in clinical practice since a great deal of effort has been invested in research into high magnetic fields to overcome the difficulties of successively working with stronger ... -
Significance of size and location of the lesion for prognosis of collapse of osteonecrosis of the femoral head for patients treated with tantalum rod
(2010)The purpose of this study is to predict osteonecrosis of the femoral head by examining location and size of the lesion of the femoral head. A triangulation approximation algorithm is used for the computation of the geometric ... -
Spontaneous spondylodiscitis: presentation, risk factors, diagnosis, management, and outcome
(2009)Background: Spontaneous spondylodiscitis is an uncommon disease, which may result in serious complications with potentially high morbidity and mortality. We conducted a prospective case study over a 2-year period in order ... -
A Swedish family with de novo alpha-synuclein A53T mutation: Evidence for early cortical dysfunction
(2009)A de novo alpha-symaclein A53T (p.Ala53 Th; c.209G > A) mutation has been identified in a Swedish family with autosomal dominant Parkinson's disease (PD). Two affected individuals had early-onset (before 31 and 40 years), ... -
Texture analysis of articular cartilage traumatic changes in the knee calculated from morphological 3.0 T MR imaging
(2013)Objectives: In the present work, we aim to identify changes in the cartilage texture of the injured knee in young, physically active, patients by computer analysis of MRI images based on 3.0 T morphological sequences. ... -
Tissue characterization: T1, t2 andt2* techniques
(2015)Noninvasive characterization of tissue has long been the unique domain of magnetic resonance imaging (MRI) when compared to other imaging modalities. Techniques for such typically emphasize one or more MR-based relaxation ... -
A tractography algorithm for MR diffusion tensor imaging based on minimum-cost path
(2016)Diffusion Tensor Imaging (DTI) is a powerful technique for studying tissue connectivity that starts to find routine clinical use in Magnetic Resonance Imaging (MRI), primarily in the brain. The extraction of tracts is an ... -
Using a modified 3D-printer for mapping the magnetic field of RF coils designed for fetal and neonatal imaging
(2016)An experimental setup for characterizing the magnetic field of MRI RF coils was proposed and tested. The setup consisted of a specially configured 3D-printer, a network analyzer and a mid-performance desktop PC. The setup ... -
Validation of a new t2∗ algorithm and its uncertainty value for cardiac and liver iron load determination from MRI magnitude images
(2016)Purpose To validate an automatic algorithm for offline T2∗ measurements, providing robust, vendor-independent T2∗, and uncertainty estimates for iron load quantification in the heart and liver using clinically available ...
