Filter by:Diffusion-weighted (DW) magnetic resonance imaging (MRI) imaging is a well established method for detecting acute injury to the brain and is used on all children undergoing an MRI brain scan at Children's Healthcare of Atlanta. The possibility of using DW MRI to study other areas of the body, such as the spinal cord, has been recognised as having great clinical potential. However, two main problems have hindered the clinical application of the technique; firstly, the extreme motion sensitivity of the technique meant that respiratory motion have hampered clinical studies. Secondly, the close proximity of the spinal cord to the bones in the spinal column complicates the application of the techniques developed for the brain to the spine. Recently, several techniques have been developed which address these problems and these are now available on the MRI scanners used at Children's Healthcare of Atlanta. We now wish to evaluate how well these techniques work on children in a routine clinical setting. For this reason we wish to add a single scan of the spine to the imaging protocol of children receiving a routine scan of the brain or spine. This will permit us to evaluate the image quality in both normal and abnormal spines. We plan on enrolling 60 patients with normal spines and 30 patients with abnormal spines. No additional sedation and/or contrast will be required and the additional imaging time for the diffusion studies will be less than 10 minutes. Parental consent will be a pre-requisite for any patient to be enrolled into the study.
ClarityIQ is a novel X-ray imaging technology, that combines advanced real-time image noise reduction algorithms, with state-of-the-art hardware to reduce patient entrance dose significantly. This is realized by anatomy-specific optimization of the full acquisition chain (grid switch, beam filtering, pulse width, spot size, detector and image processing engine) for every clinical task individually. Furthermore, smaller focal spot sizes and shorter pulses are used, which are known to positively influence image quality . The final effect on the clinical image quality is investigated in this study.
The purpose of this study is to 1) evaluate the effectiveness of the Plastizote abduction brace compared to the Pavlik harness in the treatment of developmental dysplasia of the hip (DDH) and 2) compare parent/caregiver satisfaction between the Plastizote abduction brace and the Pavlik harness. The investigators hope to learn which brace treatment is best for a definable population so the appropriate brace can be chosen initially avoiding the time, expense, and frustration of a failed technique.
The Spine TRACK Spinal Surgery Registry is a prospective multi-center observational data collection initiative, to capture clinical and radiographic outcomes in candidates for spine surgery with degenerative, deformity, and traumatic pathologies. As an observational database, there are no initial driving hypotheses, but rather data will be mined to answer unforeseen questions, but which may include broad topics such as comparative effectiveness between and among various surgical treatment options, and/or outcomes in various subgroups of patients such as defined by demographics, comorbidities, indications and symptoms, treatment variables, and/or outcome variables.
The purpose of this clinical trial is to examine the effect of non-invasive cortical activation by specific patterned auditory stimulation (Mozart K448- Piano Sonata for Two Hands in D Major), in altering or eliminating photoparoxysmal abnormalities. Recent work has indicated that such evoked activity (i.e. by specific music) can result in significant reductions, or even complete termination of epileptiform activity and/or seizures across a broad range of individuals with epilepsy. A hypothesis is generated that specific music activation would beneficially effect photoparoxysmal based epileptiform abnormalities.
This study is an access and distribution protocol for unlicensed cryopreserved cord blood units (CBUs) in pediatric and adult patients with hematologic malignancies and other indications.
This is a retrospective study assessing pre- and postoperative radiographic indices of hip dysplasia in order to identify factors predicting failure following Periacetabular Osteotomy (PAO).
The purpose of this study is to determine the effectiveness of bleomycin, fibrovein and bleomycin and fibrovein in the treatment of venous malformation.
This study is being performed to document the outcomes of subjects using our MaxAn Anterior Cervical Plate and assess them for Adjacent level Disease. All subjects will be followed for 2 years.
STUDY OBJECTIVES: To demonstrate equivalent clinical and radiologic outcomes as "gold standard" (Autologous Bone Graft) in a representative clinical model (hindfoot fusions) STUDY HYPOTHESIS: Augment® Injectable is an equivalent bone grafting substitute to autologous bone graft in applications as shown by superiority analysis for safety and non-inferiority analysis for effectiveness STUDY RATIONALE: To evaluate a fully synthetic bone graft material to facilitate fusion in conditions or injuries requiring bone graft in a representative clinical fusion model and thus the opportunity to provide equivalent union rates as Autologous Bone Graft without necessitating an additional invasive procedure to harvest the graft
