Filter by:The purpose of this pilot study is to compare a standard of care MRI scan to a non-standard of care MR imaging with portable (0.064 Tesla) MRI following the administration of non-SOC contrast called Gadopiclenol on 10 subjects with known brain tumors. Participants will be randomized to receive either standard MRI or portable MRI first following contrast injection
Modern imaging modalities, especially magnetic resonance imaging (MRI) have greatly advanced in recent years. Through technical advances, proton-based magnetic resonance imaging (MRI) has steadily increased in use to assess pulmonary structures in the pediatric population especially in Europe. Such technical developments have advanced by overcoming rapid decaying of transverse relaxation time and cardiac/chest movement synchronization, showing MRI to be feasible with respect to morphological and functional assessment of pulmonary impairment, in chronic lung disease such as cystic fibrosis for disease progression and prediction of exacerbation. However pulmonary imaging with MRI has also been feasible to detect pulmonary nodules in malignancies (allowing for spatial resolution).
The design is a single blinded, dual comparative study of ultrasound versus micro-CT/LASCA in one study group. Up to a total of 140 subjects registered will be recruited. Subjects who are treatment planned for extraction of a hopeless tooth and socket augmentation with bone graft and are planned for a dental implant surgery. The socket will be evaluated before the extraction and multi-time points during healing until an implant is placed with various evaluation tools, including ultrasound.
The purpose of this study is to elucidate the imaging mechanisms of cognitive function changes in patients with coronary heart disease before and after surgery or conservative treatment, and to evaluate and predict the postoperative neurological function recovery and cerebrovascular health level of patients by combining serum markers and patient cardiovascular health evaluation indicators.
The purpose of this study is to explore the relationship between the recovery of cerebrovascular morphology and cognitive function before and after surgical treatment in patients with carotid artery stenosis and their preoperative cardiac health status. And combined with preoperative cognitive status, serum markers, and cardiovascular health evaluation indicators, evaluate and predict the possibility of postoperative neurodegenerative diseases and the level of cerebrovascular health in patients.
Many human diseases are characterized by their ability to alter existing metabolic pathways and interrupt cellular processes. Cancer exploits the Warburg effect and utilizes greater glucose than normal cells and within this process uses anaerobic respiration, leading to increased conversion of pyruvate to lactate. This can be exploited by hyperpolarized imaging. Hyperpolarized 13C MRI imaging is an approach that utilizes a stable isotope of Carbon (13C) linked to pyruvate. MRI spectroscopy is used in conjunction with hyperpolarized 13C pyruvate in order to temporally detect pyruvate and its conversion to lactate in-vivo, in order to visualize downstream metabolic (glycolytic) activity secondary to the Warburg effect, which should be useful in detecting and characterizing tumors of various types. Hyperpolarized 13C pyruvate MR imaging has not been tested in most cancers. In this preliminary survey, we will test the hypothesis that hyperpolarized 13C pyruvate MR imaging can be used to image various cancers.
The purpose of this study is to clarify the changes of neurocognitive function of patients undergoing cardiac valve disease before and after surgical treatment under cardiopulmonary bypass operation, and to predict the neurological prognosis of such patients through combined imaging technology, so as to improve and avoid the occurrence of postoperative neurological dysfunction in such patients.
The aim of this study is to investigate the effect of a competition season on shoulder periarticular structures, muscle strength, muscle endurance, joint range of motion and upper extremity performance in young swimmers.
